femtasy Image

femtasy

The client was a German startup on a mission to revolutionise audio content market targeted at women in the DACH countries. They wanted to develop a progressive web app with a subscription-based audio streaming service with erotic stories.

In order to recognise the needs of femtasy, we proposed them a session of two workshops: Design

Workshop and Scoping Session.

The first workshop was focused on analysing the target audience through empathy maps and reviewing the client's research findings. We created 2 personas for femtasy's users and defined a high-level customer journey for the application. To finish the session with tangible outputs for the next stages of the project, we conducted a Design Studio. We focused on the most problematic areas from the user's perspective - steps in the journey which could be difficult mostly on an emotional level.

During the second workshop, EL Passion team worked on a detailed customer journey, where all the steps were listed, along with decision trees and prioritisation for future steps. Within a couple of productive hours, we have built the initial product backlog for 3 versions of the application, trying to prioritise the features to provide maximum value for the users.

Both workshops allowed us to leverage the client's knowledge and our expertise to kick-start the project with a solid foundation and a sharp focus in mind. It helped us cut the time spent on establishing the details of the cooperation, user journey and let us start working on first screens straightaway.

32000+ orgasms achieved. Over 140 stories and growing 5 every week.

Benefit Systems Image

Benefit Systems

UX Audit, UI Redesign, recommendations.


Benefit Systems offers a benefits program with many sports facilities for employees. Benefit Systems approached EL Passion and requested a sports facility research tool audit, recommendations from our team and enhancement of their existing solution.

Our UX &

UI experts conducted a UX audit and redesigned the search tool in order to ensure it is a useful and intuitive product that users will love.

During the kick-off we met with the client's team responsible for the search tool creation and received insight into the way the tool should work. Next, we proceeded with the analysis of the current solution in order to draft the scenarios for user testing.

We conducted 5 tests of the proposed solution with active Multisport users to identify the main areas for improvement. Based on the results of these tests our team provided Benefit Systems with recommendations and possible solutions. EL Passion designers prepared the clickable prototype presented to the client. After consultations and introducing some changes, our UX & UI team started working on the Visual Design phase of the project.

As a result of the efficient work of our experts, the client received a detailed audit of their initial version of the search tool as well as recommendations and ready-to-implement solutions to streamline the product. EL Passion Team provided Benefit Systems with enhanced user experience of their search tool and a beautiful user interface.

Docplanner Mobile App Image

Docplanner Mobile App

Design | Android | iOS

They go by many names: Docplanner, Znamy Lekar, Doktor Takvimi, Znany Lekarz. When they all come together, they form DocPlanner: the foremost online healthcare platform which enables patients to find local physicians and book appointments online.

Docplanner is an app available in

25 countries in multiple language versions. But it is not only the language that differs. Depending on the region, Docplanner apps offer different sets of features.

Our goal was to deliver the iOS and Android apps together with the Docplanner mobile team within a really tight timeframe.

To deal with numerous combinations of language settings and features, we built one code base that is configured depending on the country's requirements and so multiple compatible app are constantly monitored by CI (continuous integration) servers.

As fast delivery was crucial for the client, the collaboration process needed to be quick and smooth. Our mobile development team kept in constant contact with the Product Owner (Head of Mobile Development at Docplanner). Thanks to an effective decision process, we delivered high-quality mobile apps in no time.

The Mobility House Web App Image

The Mobility House Web App

The Mobility House is a leading service provider for charging solutions and installation services in Europe.

The team’s biggest challenge was to organize the complex ordering process and turn it into a well-structured system. The methodologies we use on a daily basis (UX, Agile, Lean and XP) were

a game changer in allowing us to fulfill these complex requirements. By combining several of these methodologies, we created a custom system that visualises the whole process and, at the same time, allows to setup and configure from scratch.

‘We were able to deliver our three project releases without a single day of delay. The company's name says it all. We could see, feel and enjoy the passion of this team contributing to our success story.’ - says Andreas Lahr, Head of IT at The Mobility House.

Millward Brown Web App Image

Millward Brown Web App

Millward Brown is a global market research corporation focused on advertising effectiveness, strategic communication, media and brand equity research. Millward Brown provides constant monitoring of the popularity of different parties and presidential candidates. They are routinely quoted in the nationwide news and newspapers.

Two or three months before an election it is Millward Brown that everybody talks about.

The company's default technological stack was .NET and PHP for smaller projects. After consulting with us, the customer agreed to try out Ruby on Rails. In fact, they performed a small experiment - executing the same sprint backlog with 3 different technologies: .NET, PHP and Ruby.

Not only was the Ruby sprint the sole winner when it comes to delivering all planned scope, but it was also the one to deliver extra scope!!

WP Player Image

WP Player

WP Player is a highly configurable video component.

Wirtualna Polska is one of the largest Central European web portals and one of the leaders in offering new services on the market. When WP got a licence from the National Broadcasting it clearly defined its commitment to video production. The lifestyle of their users requires the

materials to be accessible from any mobile device, putting the stability and availability in the first place. The project with which EL Passion was involved in is probably the biggest mobile project of this type in Poland, as well as in Central Europe.

The biggest challenge was to build a highly configurable component capable of working in various conditions, with different types of screens and devices, showing ads with multiple ad networks.

The team utilised the best practices to maximum. We covered the code with extensive test suite (almost 100% code coverage) and built a demo app for user testing. Our Android team prepared a very minimalistic documentation, as tests and example app served as a great reference themselves. Now the component is being used in a wide range of the WP Group applications, resulting in millions of install working seamlessly without one crash since day 1.

Tellius Image

Tellius

Tellius is a B2B Big Data analytics platform enabling businesses to unveil a wide range insights across multiple data sources.

The company approached EL Passion with a need to refresh their visual identity in full scope of UX/UI Design work to better showcase the company's vision. We were also responsible for the full

web development of the Tellius' website to show off the platform's core functionalities. The main challenge of our cooperation was to make Tellius a bulletproof selling tool.

We kicked-off by creating a general communication concept, backed up with mood boards and coloraturas schemes along with the new company logo. All to make up a good foundation for the Tellius' refreshed brand identity.

As the next step, we prepared the website's key visual corresponding to the Tellius' main feature focus. This enabled us to create full information architecture for the website and its final visual layer.

Our Front-end developers turned the mockups into a full-functional website. The application of HTML and CSS enabled us to create easy-to-use templates that the client can conveniently update and rearrange.

Cobo Wallet Image

Cobo Wallet

The Client
Cobo Wallet is the feature-rich and one of the most secure POS wallets, offering first-to-market financial products that empower users to accurate interest and dividends from their crypto holdings.

The Challenge
The previous website design was outdated and incoherent with the mobile app and the company's mission to deliver a clear

and easy to use tool for storing and using cryptocurrencies

EL Passion
EL Passion designers created responsive up-to-date website design corresponding with the company's mission and cryptocurrencies market. Getting right to the point, clear design enabled the customer to easily find all the information needed about Cobo Wallet. The unified design was inspired by the mobile app and the main goal to be in line with the company's transparency.
We used responsive design to make sure all the users can access the website and get the needed information. Clear and simple graphics made it easier to navigate through the page and underlined the trust the company wants to establish with customers.

The Outcome
We created a design for a responsive web app for the company to develop. Over 20 subpages were designed to meet the requirements of the client, current trends and to facilitate the company's mission.

Wunderpass App & Landing Page Design Image

Wunderpass App & Landing Page Design

UX, UI (re-design)

Wunderpass is a global loyalty program for travellers. All Wunderpass's attractions and experience are quality-vetted. Ken Yip, the Founder approached us asking for some additional material for an already existing design, but upon seeing how we work he decided to

redesign the whole concept.

It took the whole process and a lot of work to create an exceptional design. Web design is supposed to provide existing customers with great experience, attract new customers and has to look good on across all screens, no matter the device, resolution or screen density. A landing page created by EL Passion Team was designed to catch the eye of new customers and make them want to try out the product. But the customer's journey does not end there. It is also the flow that a user follows from the first visit, through collecting information, signup process and the very first use, to the exit moment. We've used several methodologies in order to explore all the user's needs. We've detected all the details, such as a signup form, that could have tremendous impact on user acquisition.

Remitsy - web app Image

Remitsy - web app

UX/UI Design | Front-end | Back-end

Remitsy uses Bitcoins to make fast payments to your international suppliers.

Remitsy wanted to quickly start the project with a long list of constraints including security, legal and technical

aspects. Another challenge was to integrate all the legal and security issues into a usable interface. On the other hand the service did not have a direct competitor, so we had a lot of freedom when it comes to the design.

Each time we face a tight timeframe, we thank ourselves for the hard work and engagement we invest in perfecting our processes on a daily basis. Thanks to them, we were able to smoothly go through the design and development phases. Our approach helped to kickstart and deliver the first working version really fast.

Feedback summary: 

The engine has successfully replaced old functionality, enabling campaign tracking and meeting the expectations of the internal team. EL Passion is helpful and responsible, providing suggestions where necessary. The team leverages their experience and expertise to deliver quality results.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

Varner is one of Northern Europas biggest fashion retailers with more than 1400 stores, mainy in Scandinavia. I work as a Product Manager in Varner.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire EL Passion?

ElPassion was hired to build a custom made Price and Campaign engine for Varner - to enable Varner to have one common campaign engine across online and offline channels.

What were your goals for this project?

The goal was to create a smart, AI, based price and campaign engine - to enable Varner to track all price changes, dynamically change the price to optimize sales and margins and be able to create campaigns based on stock status. From a customer perspective, we wanted to be able to give the customer better overview and insight in available campaigns and eventually offer individual prices.

SOLUTION

How did you select this vendor?

ElPassion was selected based on previous experience from other projects within Varner`s former partners.

Describe the project and the services they provided in detail.

Varner decided to build a new retail stack, where Price and Campaign, in the first phase should have full ownership of prices and all changes in prices, together with campaigns. This was integrated with the new e-commerce platform that was build at the same time.

The key features with be, prices and all possible campaigns. In addition to this, we built Markdown, an AI controlled price optimization application for end of season sales.

What was the team composition?

The team was, for most of the time that follows:

  • Backend Developers
  • 2 ElPassion Fullstack Developers
  • 1 ElPassion Frontend Developers
  • 1 Elpassion UX designer
  • 1 Varner
RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

The Price and Campaign engine replaced old functionallity and cannot demonstrate prowen impact at this point. But it enables us to track campaigns and price changes better and are built in a way that we easily can add features in comparison to old 3 party applications. Markdown has proven to additional upsale of old products, in end of season sale, between 65 and 100 MNOK, and have huge impact on Varners long term margins.

How was project management arranged and how effective was it?

Project Management was my responsibility and everything that was ineffective was based on my lack of experience. The ElPassion team was very helpful and great partners to set up a project managment to secure efficiency.

What did you find most impressive about this company?

I would say the most impressive strengths of the team from ElPassion would be their ownership to the product we built. They are knowledgeable and efficiently figure out solutions to roadblocks and problems.

Are there any areas for improvement?

There could be more flexibility to have more on site workdays, but I did not require this and we maintained good communcation even we worked from different countries.

EL Passion has played a core role in driving business improvements. The flexible team is accommodating and easy to work with, agreeably switching between big development tasks and maintenance services as needed. They communicate seamlessly.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I work for entrafin GmbH, a trading platform that does digital trade finance. I’m the head of sales for Cologne, Germany.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with EL Passion?

We wanted to upgrade our app. We don’t have our own technical person, so we need to have good people taking care of our app, as all of our business is on it. We need to be able to get quick answers and help when needed, especially with maintenance.

SOLUTION

What was the scope of their involvement?

EL Passion has helped us develop our app for international business trading. They changed our UI/UX and enabled partial billing. Because we are a digital trading platform, we have to go through a lot of steps to adhere to regulations.

What is the team composition?

We have two developers and one account manager.

How did you come to work with EL Passion?

They were recommended to us by another company who had worked with them before. Communication is easygoing, which is why it is a perfect fit.

How much have you invested in them?

We will have spent $30,000–$40,000 this year.

What is the status of this engagement?

We began working with them in 2016, and the engagement is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Adding the partial billing and international trading capabilities was a huge step in improving our business. EL Passion is able to book new options for our development needs quickly, and they are really flexible. If there is a specific developer we want to work with because we worked with them before, it is easier, because they know the project.

How did EL Passion perform from a project management standpoint?

It has been really easy to book and plan sprints. EL Passion has also easily switched between doing huge development tasks and normal maintenance. We can get help quickly. 

Communication is great, but it might be better to meet up in person before doing a big project instead of doing so via Skype. All other communication has been easy and quick, even if we’re in two different countries.

What did you find most impressive about them?

The team’s skill level and ability to communicate have been impressive. Even if we don’t understand the questions, or if they don’t understand what we mean, it is always smooth to talk to them, and they are easy to work with. We never hesitate to call them and ask questions.

Are there any areas they could improve?

It would be good to have some advice when it comes to what is best for the app, but that is a very small thing.

BACKGROUND

Please describe your company and your position there.

I am the COO of Gignative, which connects clients with high tech suppliers side. We connect mostly US/ UK clients with Polish market due to one of the best competencies in the world in software development.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire EL Passion?

One of our clients was interested in creating a new software for financial services from the scratch. The idea was to check first how it can look like so the business side can do the user experience tests first and check the results. We decided to cooperate with El Passion's UX and UI designers.

What were your goals for this project?

We wanted to check the first reaction of users and check what the biggest benefits so it was very important to have a clickable version of designs

SOLUTION

How did you select this vendor?

We have already seen previously the work done by El Passion's designers so we decided to do the project with them this time without even looking for alternatives. We had a chance to talk first to the UX senior designer to understand their ways of working and what do they pay attention to. After the first meeting we already knew how good the UX designer is.

Describe the project in detail.

We decided to start with a couple hour's session to understand the goal of the project, the industry and the final user's expectations. We draw the whole process of user's journey and we had a brainstorm together to eliminate non added values.

After the session we started to produce and discuss in details the first mockups. Once we were at the point that the first mockups were accepted by all stakeholders, we went further to produce the rest of it.

What was the team composition?

UX designers UI designers Product Owner Frontend developer

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

We were able to deliver the package of mockups (including UI) for the first stage of the project within a month, which was expected by the client and the feedback from end users was great.

How effective was the workflow between your team and theirs?

It was very important the the communication from the designers was so clear. The product owner knew exactly what and when is required from him, the process was set up in an easy way so you could always take an action or check what the status is.

It was super clear and super fast delivery mostly to the fact, that both sides (product owner and the designers) were very responsive and they responded very fast to their awaiting actions

What did you find most impressive about this company?

I was blown away by how detail-oriented they were. They went so much into the details that I have never expected that such case corners can arise that I would have never think of. At the end of the day it saved my time on development

The team at EL Passion exceeded expectations, delivering high-quality design work. All external and internal feedback has been positive. New and old customers are impressed and re-engaging. Their responsiveness and communication style were top-notch. Customers can expect a team open to feedback.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the product manager at an HR tech startup that provides employee engagement and lifecycle survey products to companies of all sizes. I’ve been working there for about a year.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with EL Passion?

Our platform allows users to view data analytics for surveys they’re conducting. In the beginning, the platform was thrown together to get the product out there for customers. As a company, we needed to do a complete refresh of our frequently-used product.

SOLUTION

What was the scope of their involvement?

EL Passion redesigned the UX/UI of our entire analytics platform. The product includes data analytics for three product modules. It also has the ability for customers to manage their company settings and user databases, launch surveys, and poll out to their employees. We looked at their work through InVision, providing feedback and iterating on their designs.

What is the team composition?

We worked with two people.

How did you come to work with EL Passion?

Before I came aboard, our CEO engaged with EL Passion. The reason we met with their team was that our company is distributed internationally. We’re based in the US, but working with a company in another time zone isn’t an issue for us.

We were looking for an agency to complete the redesign without having to invest our resources in bringing on a full-time UX designer. We needed flexible support that fit within our budget. Outsourcing to a company in Europe provides that.

What is the status of this engagement?

We worked with EL Passion from September 2018–April 2019.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Everything was completed earlier this year. I emailed them just today about a different project. The engagement was a resounding success. The work that their team delivered was a vast improvement over what we had before. In terms of customer experience, our product is at the top of the market. Customers and prospects have said it’s one of the best platforms they’ve seen on the market. It offers a better experience for customers.

Internally, the feedback was also excellent. All of our teams are engaging with customers and people looking to reengage with. Everyone was blown away with how much better the product looked. It’s made the difference in securing deals moving forward.

How did EL Passion perform from a project management standpoint?

Our working relationship with EL Passion was great. They’re incredibly responsive and open to our feedback. Their team works in an agile manner, reacting to changes quickly. We’ve worked well together despite being in different time zones. We would meet a couple of times a week, going over updates and providing feedback. We also had an open communication through Slack, where we would send input, and they’d send updated designs.

What did you find most impressive about them?

The communication between our team and their designers was excellent. They were available, even after we started implementing the work. They were engaged, checking down the road whenever we had questions and anticipating when the designs would go live. Their team wanted to see it up-and-running. Their level of enthusiasm was phenomenal.

Are there any areas they could improve?

No. From my perspective, our experience was positive.

BACKGROUND

Please describe your company and your position there.

Booksy is a booking system for people looking to schedule appointments for health & beauty services. Customers can download the app (available for Android & iOS) to find local services. I’m the co-founder and CPO of Booksy.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire EL Passion?

We decided that to provide better value for our clients, both of our apps, Booksy (B2C) and BooksyBIZ directed at B2B customers [partners], needed a redesign and functionality refreshment to better correspond to the ever-changing market situation.

We reached out to EL Passion to help us with both, the design and development of the apps. The B2B-targeted app needed an update for two mobile platforms, iOS and Android, whereas our main app, Booksy (B2C) required UI&UX assistance on the IOS OS.

What were your goals for this project?

The main focus of the B2B app update was the introduction of some key strategic features, i.e new businesses onboarding and the addition of message blasts strongly suggested by our partners in the course of time. We also wanted to refresh the design.

For our B2C app, the crucial element was to adjust it visually to the overall iOS OS look and feel and to make it compatible with various screen sizes. With these tweaks applied, we aimed at increasing our booking number by 50%.

SOLUTION

How did you select this vendor?

We were looking for a partner who could help us in both design and development and do so in a relatively short period of time. We heard about EL Passion from Docplanner, one of EL Passion’s former clients. They were very satisfied with the quality of cooperation as well as the end result and that contributed highly to our final decision to pursue our project with them.

Describe the project in detail.

The project kicked off just after our signing the contract; EL Passion’s designers conducted several in-depth interviews with us regarding our UI and UX expectations to gain a profound understanding of the challenge. The team of assigned developers and designers started the project directly from our office so it was convenient for us to issue any ad-hoc concerns.

After the introductory period the project was continued remotely and, thanks to the tools introduced to us by the EL Passion team, it turned out to be very efficient. The EL Passion team suggested the Scrum methodology for our cooperation and provided us with finished elements of the project by the end of every sprint. The method was effective and allowed us to keep control over the whole process.

EL Passion successfully delivered all requested screens and designs with the refreshed UI & UX as well as developed new desired functionalities for our B2B app.

What was the team composition?

The project was realised in two parts. During the first iteration, a team of 3 iOS developers and 2 Android developers helped us to develop a new version of our B2B app.

Later, 3 iOS developers and 2 UI/UX designers recreated the navigation and information architecture. Our Product Owner was working directly with the developers which was convenient and streamlined the whole process.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Thanks to EL Passion we were able to create apps meeting all of our previously established expectations. The B2C app improved our client conversion bringing a significant increase in the booking numbers.

Since the launch, we received positive feedback from our Partners regarding the changes in the B2B application who noticed the enhancements and appreciated the introduction of new functionalities.

How effective was the workflow between your team and theirs?

Our team remained directly involved in the whole process and thanks to the initial two-team cooperation we were able to establish well-performing communication channels.

The introduction of the necessary tools on the EL Passion’s side alongside their unshaken way of results delivery benefited the pace and quality of the communication. They were always there ready to share their knowledge and expertise.

What did you find most impressive about this company?

We continue to be impressed with EL Passion’s team professionalism and their extensive skill set. Our cooperation remained smooth throughout the whole project, we were regularly updated on the apps’ status and could test and improve elements right away.

The end-result UI designs and animations were stunning, and they are probably the major factor why we would/will [stronger] choose to work with them again.

Are there any areas for improvement?

Initially, we thought that we could add ad-hoc features after the project’s closure. However, we had to go for the maintenance offer to apply any changes. We would appreciate a more flexible solution for that.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I’m the CTO at Humon. We empower people with actionable insights about their body, allowing them to be the best version of themselves. Our first product measures how muscles use oxygen, which is the best metric of physical exertion. With this data, our algorithms prescribe the perfect pace and workout intensities in real-time, provide post-workout analysis about how the body is responding, and suggest future activities based on this information.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire EL Passion?

Our company hired EL Passion to aid our in-house team in developing our backend application and infrastructure.

What were your goals for this project?

Our goals with EL Passion were to take an existing but primitive backend application and get it production-ready. This included adding features, improving reliability, and refactoring code for future scalability and maintainability.

SOLUTION

How did you select this vendor?

EL Passion was introduced to me by another firm with whom I had very successfully worked with. I trusted the party making the introduction and was pleased with the initial interactions I had with the team at EL Passion, so I made the selection to work with them.

Describe the project and the services they provided in detail.

Once we selected EL Passion, their engineers integrated quickly and seamlessly into our in-house team of developers, as well as the other contracting firm which was working on our mobile application. We all shared a single instant messaging channel, where EL Passion immediately became part of our cohesive team. They coordinated with the rest of the team to build changes to the backend to support the work of the mobile team. This required working in concert to roll out new features, fix bugs, and future-proof the backend codebase.

What was the team composition?

The EL Passion team has scaled as necessary to meet our internal needs, but the average composition involved a senior engineer and mid-level engineer.

RESULTS & FEEDBACK

Can you share any information that demonstrates the impact that this project has had on your business?

We met our initial deadline and had a successful launch. Now, we’re continuing to improve the app by fixing bugs, adding features, and enhancing its design. As a young and growing business, we’ve faced many challenges, but our software hasn’t been a bottleneck.

How was project management arranged and how effective was it?

Overall, our workflow has been seamless. EL Passion's engineers are pleasant and professional to work with. Direct and constant communication between our two teams has been critical to operating efficiently. Our successful collaboration wouldn’t be possible without the excellent communication between our team and every member of their team.

What did you find most impressive about this company?

I have been most impressed by the knowledge of the EL Passion team and their ability to integrate so easily into our existing team. Without either of those attributes alone, success would not have been possible. Having strong technical skills and knowledge to discuss and think through problems in real-time together made our collaboration a success.

Are there any areas for improvement?

The benefits of strong communication with the EL Passion team have been clear and described above. This was achieved with each team member throughout our collaboration. The only area to improve was that this process was a bit different for each team member, with their hours and schedule all a bit different. Having a consistent and transparent understanding of the expected process from the start would have helped.

Feedback summary: 

El Passion successfully delivered the first version of the applications, which have received promising initial feedback. Their team’s success has fostered an extended engagement. Professional and adaptive, El Passion is committed to meeting client goals and having a smooth workflow.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I'm the CEO of a health startup.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with El Passion?

Our first attempt at building a platform for health professionals with another development company was not successful, so we engaged El Passion to take over the project.

SOLUTION

What was the scope of their involvement?

We wanted to develop a mobile application for Android and iOS that allowed health professionals to follow up with obese patients while they are at home. Users can enter their personal information and updates into the app and then start a dialogue with their healthcare provider through the platform.

When we engaged El Passion, we had a clear set of specifications because we had already begun working on the app with another partner. We held a kickoff meeting to transfer all of our existing work to El Passion and give them more of an understanding of what we were aiming for. They figured it out quickly and ultimately delivered what we wanted.

What is the team composition?

We work with a technical team of about five people.

How did you come to work with El Passion?

Their CEO contacted me several times in the past, but we were never in the position to hire them. Luckily, she contacted us again while we were searching for a new partner. We discussed our project through a series of calls, and we selected El Passion after also interviewing a few other companies.

El Passion made a really good first impression. They were curious and understood our needs. And they followed-up nicely after the meeting. All of the companies followed-up, but El Passion really stood out.

How much have you invested with them?

We expect to spend about $250,000.

What is the status of this engagement?

Our work with El Passion began in February 2019 and remains ongoing. Our system is up and running in a pilot phase now, and we’ve decided to continue working with El Passion for building our next version.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

Two local students are writing their master’s theses on our project, so they have researched the implementation of our system. Through their interviews and surveys with patients and health professionals, we’ve received a lot of positive feedback. The system is somewhat basic, but users have liked it. We had a few small issues once we first launched it, but El Passion solved them quickly. Since then, the app has been quite stable.

How did El Passion perform from a project management standpoint?

They are quite professional in how they run the project. We have daily standups, and they adapt quickly to our preferred methods or strategies. In that regard, they’ve been straightforward to work with compared to past vendors.

What did you find most impressive about them?

Their flexibility and willingness to pivot when we think is necessary is really appreciated. Their curiosity makes them stand out. They are invested in our project and meeting our goals.

Are there any areas they could improve?

I'm quite happy with them. I have no areas for improvement for them.

Do you have any advice for potential customers?

I'd recommend being on the project every day yourself, as opposed to leaving all the work up to them. You have to be involved in some way.

With carefully written code and a creative design, EL Passion delivered a functional product that is worthy of being introduced to a broader audience. The team had little trouble communicating across time zones, and they were mindful of all requirements.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I am an engineer at a technology development company. We deliver web services through various applications and domains.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with EL Passion?

We hired EL Passion for a rapid build of a new application that we're considering launching.

SOLUTION

What was the scope of their involvement?

Our company designed and built a proof of concept internally for a user behavior analysis tool, which would help website owners track user activity and collect feedback from users. We demoed it to EL Passion and asked them to provide a more professional design and assist in building a prototype. We agreed to a collaborative partnership in that they would develop the frontend using React while our in-house team maintained the backend.

What is the team composition?

We had one full-time designer for the first month or so and then brought on a full-time developer and a part-time junior developer.

How did you come to work with EL Passion?

We had worked with EL Passion on a previous project, so we already had a decent working relationship with them.

How much have you invested with them?

We spent about $45,000 with them.

What is the status of this engagement?

Our engagement spanned February–May 2019.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement? 

They definitely met the requirement of coming up with an intuitive design and helping us bring our idea from an initial prototype to something that we will be proud to present to a broader user base.

How did EL Passion perform from a project management standpoint?

We communicated daily through Slack, and we used Jira for development tasking. EL Passion did a good job of giving us project updates. There were no bottlenecks in terms of communicating.

What did you find most impressive about them?

The designer we worked with was the strongest resource for us. We could tell he took a personal liking to the project. He engaged regularly and had a lot of opinions and ideas, so it was like he was part of our in-house team.

Are there any areas they could improve?

No. EL Passion did everything we asked of them, and they were very accommodating throughout the process.

Do you have any advice for potential customers?

When working with an outsourced team, in general, it’s vital for the internal team to maintain the work that’s being done. We had to find that balance so that we picked the appropriate time for EL Passion to transition the product back to us near the end of the development process.

BACKGROUND

Please describe your company and your position there.

I am a senior digital marketing specialist for a company that offers non-wage benefits to companies in Poland and other European countries. Our main product—MultiSport Program—gives our users access to sports facilities.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire EL Passion?

Through our website, we offer our MultiSport users access to seasonal activities and promotions. Winter activities are among the most popular, and we needed to create new content on our site presenting a new offer in a very short time. We hired EL Passion to design graphics and new subpages.

What were your goals for this project?

We hoped to create a modern and friendly UX design that presented our latest offer.

SOLUTION

How did you select this vendor?

We hired EL Passion because we believeD their offer and dedication were the most suitable for us. At the time of the engagement, we also had an ongoing project with their team, and we were satisfied with the results they had provided.

Describe the project in detail.

EL Passion had only seven days to deliver all of the graphic designs of the website. During our initial briefing, we discussed our expectations and business goals, and we provided them with the required specifications of the project.

Within two days, EL Passion delivered low-resolution mock-ups of three subpages—complete with new illustrations, GIFs, text, and photos. We gave them some feedback, and their designers began work on more high-quality mockups. The designers finished their work on time, but they did not provide a responsive web design (RWD) version. They claimed they did not have enough time to do that. We afforded them one extra day to deliver an RWD version. They fulfilled all of their obligations once we had an RWD version.

What was the team composition?

We had direct contact with two designers and a project manager.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Our website developers were satisfied with the completed designs. We constantly receive positive feedback about the graphic elements of our website.

How effective was the workflow between your team and theirs?

Our teams used Slack to communicate and InVision to upload designs and provide feedback. Overall, it was very easy to work together.

What did you find most impressive about this company?

EL Passion demonstrated professionalism, flexibility, and dedication from start to finish. They delivered results that met our expectations. Our project manager was always supportive and eager to solve any issues.

Are there any areas for improvement?

No, I don't think any other company could deliver better solutions in that tight of a timeframe.
