Feedback summary: 

JatApp’s quality work continues to exceed expectations. Their QA experts rapidly resolve any bugs, while efficient project management and transparency through every project stage builds confidence. Their accurate and prompt delivery is also impressive.

BACKGROUND

Introduce your business and what you do there.

I’m the COO of a startup with six employees that got funding to develop a cryptocurrency application.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We decided to outsource because we didn’t have enough in-house expertise. We ended up hiring two blockchain developers through JatApp.

SOLUTION

What was the scope of their involvement?

They’ve used Python to write some parts of the backend code. They also have responsibility for some of the backend models and provide team members for the mobile side as well.

We discuss the scope, priorities, and specifications with the project manager who then translates tasks to their developers. Our work process is built on that communication and interaction.

What is the team composition?

There are two developers who we don’t have contact with directly. Some of our in-house developers collaborate with JatApp.

How did you come to work with JatApp?

We met at an event in Finland. We considered other companies in Ukraine and Eastern Europe. JatApp had good expertise and their proposal was detailed and straightforward.

How much have you invested with them?

We’ve spent $100,000.

What is the status of this engagement?

We started working together in November 2017. The project is ongoing.

RESULTS & FEEDBACK

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

We’re happy with how they work and their deliverables. They’ve delivered 95%–98% of what they promised. The quality exceeds our expectations. Their QA experts have been able to quickly fix any bugs. They have a good grasp of what they’re doing. We’re happy working with them.

How did JatApp perform from a project management standpoint?

There’s transparency around every stage of development. They have a backlog that we discuss with them and through which we manage all priorities. The developers discuss things directly with the project manager who then provides us with an estimation. They’re good at estimating and managing all of our expectations.

We use Slack and have weekly or bi-weekly calls via Skype to discuss the project’s status. We work in an iterative process. We normally get additional functionality every three weeks. They deliver on time.

What did you find most impressive about them?

They've been strong in delivering what they promised to initially. They are committed to the final result.

Are there any areas they could improve?

Everything has gone smoothly. They require no major improvements.

Do you have any advice for potential customers?

Try to share all of your technically-focused ideas and business problems with them. They might challenge you a bit. Communicate and share as much as you can. They’ll definitely give an initial structure of the future development process.

Feedback summary: 

JatApp succeeded in delivering an efficiently functioning MVP, enabling product demonstrations to future partners. They manage the project with autonomy and accountability, meeting all deadlines. Their high-quality services make them an integral part of the app’s future.

BACKGROUND

Introduce your business and what you do there.

I am the CTO of a medical startup developing a mobile app for iOS and Android. Patients and doctors can use the app for managing appointments and initial consultations without leaving their homes. After requesting a consultation, a patient can receive instant, personalized messages from their doctor. We are promoting our business locally, and we anticipate signing our first contract soon. Later on, we plan to expand internationally.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We were looking for a development team to continue the work on our MVP. We had built a backend using a previous supplier, but it didn’t work well. The main challenge was developing the product within the deadline and making sure that it would work.

SOLUTION

What was the scope of their involvement?

JatApp provided backend development for our native iOS and Android apps. They took some parts of the existing backend but wrote the mobile app from scratch. The Android app was written in Java and the iOS app was done using Swift.

The key feature of the app is booking remote appointments. Another feature is that patients can chat in real time with their doctors and doctors can provide instructions via the app. For an additional fee, we also provide a video-calling feature. Finally, the app also enables patients to order medications using the app.

They’re currently supporting our MVP version, and there are features we are planning to launch in 2018.

What is the team composition?

They assigned a project manager, a backend developer, two Android developers, and two iOS developers. The PM was responsible for making reports and keeping us informed.

How did you come to work with JatApp?

We met their team at the Web Summit and discussed our startup. Later, we visited their office and met the team.

How much have you invested with them?

The cost has been around $70,000.

What is the status of this engagement?

We started working with JatApp in November 2017 and have an ongoing relationship.

RESULTS & FEEDBACK

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

We currently have an MVP that we can present to future partners. We have received positive feedback from clinics, which is the main indicator of JatApp’s quality of work.

How did JatApp perform from a project management standpoint?

The project was divided into milestones, each with a specific deadline. The work was delivered on time. We’ve worked with a responsible project manager; he was in charge of the process on JatApp’s side keeping our involvement minimal.

We have weekly Slack meetings for updates and planning for upcoming releases. They’ve always been happy to hear our opinions.

What did you find most impressive about them?

Working with them is a professional yet friendly experience.

Are there any areas they could improve?

We have been satisfied with their work so far.

Do you have any advice for future clients of theirs?

I would definitely recommend them to anyone looking for good mobile development services. They are a good fit for someone who wants to have minimal responsibility on the project management side.

Feedback summary: 

The app that JatApp built was well-received, with some users using premium, paid features. The team corrected bugs quickly (including those not of their own making) and responded equally as promptly to other concerns. They also offered useful tactical advice that was implemented subsequently.

BACKGROUND

Introduce your business and what you do there.

I am the remote COO of a U.S. company that focuses on creating and providing a networking app. It allows users to find and be found by others around them using the GPS on a smartphone. The app was created for conferences and other events where people can meet investors, business partners, or new friends.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

Our main idea was to create a simple and business-oriented app with the goal of extending business networks. The challenge was finding a company that could help us with the app.

SOLUTION

What was the scope of their involvement?

We asked JatApp to develop a native smartphone app. We sketched out the time and budget estimation. Based on this, we decided to start development on a light version for which users could order extra features for a fee. We gave their team the branding book and design guidelines. 

When first opening the app, users are prompted to create an account with a username and password. Photos can be uploaded to the account. Then, they decide if they want to allow others to see their profiles in full or in part and allow others to find them. There is also a messaging function, but it’s something we want to improve.

We recently updated the latest build to fix bugs and make other improvements. We continue to work with them from time to time on the app’s frontend. We plan to develop some new features in the next three or four months. We want to create a white-label solution based on the app.

What is the team composition?

Their CTO took part in our first call, but after that, we worked primarily with two mobile developers, a QA person, a project manager, and a sales manager. Their CTO took part in our first call.

How did you come to work with JatApp?

We found them on LinkedIn. We sent a message to JatApp’s sales manager and scheduled a call for the next day.

How much have you invested with them?

We spent $60,000.

What is the status of this engagement?

Our first call with JatApp was in January 2015, and the project started in February. We finished the work in July of that year.

RESULTS & FEEDBACK

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

Everything went smoothly. Since the first release, we’ve had more than 500 downloads. Users like the app, and several use the paid features.

We had bugs caused by third-party integrations. The first iOS build was better than the Android one, but they fixed the issues.

How did JatApp perform from a project management standpoint?

They provided responsive communications and good management via Skype, Slack, Google Hangouts.

What did you find most impressive about them?

They provided important feedback about our ideas, then we understood that some of those wouldn’t enhance the work well for the app’s user experience. This feedback was valuable to us and we decided to take JatApp’s advice.

Are there any areas they could improve?

We had problems with the pricing, but we negotiated and they agreed on a discount. We don’t have any complaints currently.

Do you have any advice for future clients of theirs?

It’s important to gather feedback from previous customers and ask for their impressions about working with the development company. Clients should also check the provider’s design portfolio and download their apps in order to look at features and bugs.

The Review
Feedback summary: 

User engagement was highly positive throughout testing, due to the applications' fluid UX and dependable performance. JatApp's developers had a strong grasp of Agile methodology and solid communication practices, which enabled them to deliver on time and meet high quality standards. 

BACKGROUND

Introduce your business and what you do there.

We came up with the idea for an alternative travel application that allows users to easily share destinations, experiences, education, and health habits. I was a project manager for the company and was in charge of a six-person team at the time.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We needed to find a partner who could develop a reliable iOS and Android application based on our idea.

SOLUTION

What was the scope of their involvement?

JatApp dedicated a team to native Android and iOS development, using native technologies with modern networking database frameworks for both operating systems. They also used support services like Firebase, Crashlytics, and Fabric. The backend and server elements were completed by our team.

They gave us a proposal, which included the various technology stacks to be used, and we discussed the project with their developers.

The app’s key purpose was to give users the ability to mark interesting places, travel routes, and experiences. While someone is visiting a country, they can log in to our application, log their experiences through different routes, and share them with others.

What is the team composition?

They assigned two dedicated iOS and Android developers. We had a designer and project manager on our side.

How did you come to work with JatApp?

We reviewed multiple companies, trying to find the most suitable technology stack and pricing. We met one of JatApp’s business representatives at the Web Summit in Portugal and decided to hire two iOS and Android developers from their team on an outsourced basis. After our initial meeting, we had some Skype interviews with their development team and fell in love with their approach.

How much have you invested with them?

The total cost of their services has been around $80,000.

What is the status of this engagement?

We started working with JatApp in the early part of 2017. The technical phase has been completed, and we’re currently planning a software release and working on the commercial aspects of the project. JatApp was only responsible for the software development component, so our collaboration has ended.

RESULTS & FEEDBACK

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

We are fully satisfied with the application’s user experience and stability, and user engagement was satisfactory during alpha and beta testing. Since we are still commercializing the app, we will have more detailed statistics in the future.

Our technical specialists have assessed their approach and code quality as excellent. JatApp gave us a very good development team.

How did JatApp perform from a project management standpoint?

Since project management responsibilities fall to us, JatApp has only worked on outsourcing the development team. We used an Agile methodology, with separate sprints and clear communication channels. There were some changes from our side, but every build was delivered on time.

What did you find most impressive about them?

The main point I can highlight is product quality.

Are there any areas they could improve?

We are fully satisfied with everything, but their prices are a bit too high.

Do you have any advice for future clients of theirs?

Clear communication channels and team dedication are important for controlling the development process.

Feedback summary: 

After receiving disappointing results from a previous vendor, JatApp’s involvement is refreshing. The new system is live, working well, and evolving, as well as garnering some distinguished end clients. Regular communication and exemplary customer service continue to impress.

BACKGROUND

Introduce your business and what you do there.

Our company’s platform makes shoppable ads that enable web users to buy products without having to go to an e-commerce website. I’m the project manager.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We had another team of backend developers in the U.S. who were working on the first version of our platform, but it was a mess. The challenge was to find good, English-speaking, experienced senior developers in a short period of time.

SOLUTION

What was the scope of their involvement?

They deal with all the tasks that our CTO gives them which are strictly concerning the backend software. They started with factoring and partly redeveloping the backend that our previous team developed. They’re also working on some additional work for other clients. We have a contract right now with a prominent manufacturing company who wanted to use our platform for marketing purposes.

Our platform will eventually act as a white label solution. We needed all those integrations between the manufacturing company and the ERP [enterprise resource planning] system. Many of the initial months were spent on the introduction of this key contract that we have this year.  

It’s a platform that allows users to make purchases by clicking a link on an ad, eliminating the need to interact with an e-commerce website. Products automatically go to a basket and the system sees it as a purchase.

What is the team composition?

I was initially in touch with their HR department head as they sent me the CVs. There are four full-time senior developers working with the mobile team who are also located in Ukraine. There is a project manager in charge of scheduling interviews and making sure we have the right equipment for communicating with our developers in the future.

How did you come to work with JatApp?

A friend who often travels to Ukraine from the U.S. had previous experience working with JatApp and said it might be worth contacting them.

They didn't have the internal expertise we needed initially, so we allowed their HR team to look for developers who we then interviewed. It took us a while to go through this process and shortlist developers who matched our requirements. We then had to wait for JatApp’s HR to make contract offers to the developers. We found four senior developers within one month due to their help.

How much have you invested with them?

We’ve spent $100,000.

What is the status of this engagement?

We started working together in January 2016, and the relationship is ongoing. We will continue working with them for at least this year because there’s a lot more work to do.

RESULTS & FEEDBACK

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

We managed to refactor the work that the previous developers did, which we didn’t think was possible. We took the risk of redeveloping the entire system from scratch. We wasted one year of investment with the previous developer and received poor results.

However, the experience with JatApp has given us great results. The system itself is working really well now. We have more clients who are wanting to become our partners. The prominent manufacturing company is just one of many huge clients. We have great opportunities opening up due to our collaboration with JatApp. The best metric is that the system is live, working, and growing.

How did JatApp perform from a project management standpoint?

We try to manage everything on our side. They communicate directly with our CTO and CEO. We have weekly standups with them as well. We’ve never met in person, but we do chat a lot and have video calls at least once a week. We usually communicate via Slack.

What did you find most impressive about them?

Their HR services are the most impressive thing about them. When we were looking for developers, we realized it might take two weeks to find the right people. JatApp suggested that their HR work for us during that time for free. They didn’t charge for interviews, the time their managers spent looking for people, or the time we spent with their project manager.

Are there any areas they could improve?

No, everything is going well. 

Do you have any advice for potential customers?

People looking for backend developers should still consider companies that may not have the appropriate resources right away. Wait for the company to find and hire those resources. Take at least 20–30 interviews to find a couple developers you want to work with.

BACKGROUND

Introduce your business and what you do there.

I’m a project manager at a property loan company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We wanted to reduce the amount of time people had to spend to receive answers to whether they receive a loan or not. We wanted to reduce the number of people working in some of our departments to save the company money. We decided to have an app developed.

SOLUTION

What was the scope of their involvement?

They developed our mobile app. Our app helps people go through the loan process more easily. They just have to answer some questions. The app is for both the applicants and for our admins who are the decision makers. There’s a special admin panel that allows admins to see the users’ answers, and they make decisions based on that data.

The app is for iOS. They used Objective C. The backend was based on PHP. After we released the app, they did some improvements and added more features.

What is the team composition?

I communicate with Anna [Business Development Manager, JatApp]. She communicated with the technical team.

How did you come to work with JatApp?

They found us. We received an email from them offering development services. It was great timing because we were thinking about starting a project.

How much have you invested with them?

We’ve spent $58,000.

What is the status of this engagement?

We worked together from March 2017 until September 2017.

RESULTS & FEEDBACK

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

A lot of people used the app. We have a lot of requests. It’s quite popular.

How did JatApp perform from a project management standpoint?

We had discussions about deadlines because we wanted to make it faster. They explained that some things need more time. We always knew when it would be finished. They were quite responsive. My colleague talked with them. I only handled the business side.

What did you find most impressive about them?

I like that our requests were answered within 15 minutes. They were fast with communication. I like that they didn’t charge us for bugs that were found. They were quite transparent and we always knew what was going on.

Are there any areas they could improve?

Everything was quite good. There weren’t any problems.

Feedback summary: 

The completed iOS application was well-built with the team offering high-quality deliverables. They were happy to make changes as required and completed these quickly and reliably. The team maintained friendly and professional communication and offered ideas for improvements.

BACKGROUND

Introduce your business and what you do there.

We provide a social media app for the organization of private events. It’s an idea we’ve worked on for a couple of years.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

It was a challenge to find a good software house to build our app. Every group we approached told us it would be too difficult. JatApp offered to build our app, which excited us, since we thought that making our idea into reality would be challenging.

SOLUTION

What was the scope of their involvement?

We brought them our idea along with a mockup of the app. It was difficult to explain the idea, so it was important for us to bring screenshots that illustrated what different buttons would do. They studied our concept over a month-long period and asked us clarifying questions. After this, they worked on a general build that served as the basis for our iOS app, and which can be ported to Android in the future.

The first screen is a map showing different parties created by users. After a host creates a party, it will be displayed within a two-mile radius of its real position. Once a participation request from another user is accepted, that person will be able to see the real location of the party, along with other details.

Another important functionality was around people: someone can choose a location, and see where the nearby people are going to party. There is also a feedback functionality similar to that of Uber. After finishing an event, a user needs to leave some feedback, before being able to use the app again. It involves giving a heart; nothing more complicated like text feedback.

What is the team composition? 

They assigned four or five people to the app development, including a couple of engineers.

How did you come to work with JatApp?

We had a couple of meetings with different software houses and understood that we needed to find a reliable partner. We sent emails to five or six companies, out of which JatApp seemed to be the best option. They liked our idea from the beginning and gave us a professional impression.

How much have you invested with them?

The cost of their work has been $50,000.

What is the status of this engagement?

We first contacted JatApp 13 months ago, around November 2016. The app was launched in August 2017, but we’ve unpublished it due to some internal changes in our company. After solving our internal issues, we are planning to build an Android version using JatApp.

RESULTS & FEEDBACK

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

JatApp was professional from the beginning, assigning two people just to understand how the app would work.

The overall results were good. There were some aspects that we wanted to change—sometimes based on mistakes from our side—but they were quick to make those changes.

How did JatApp perform from a project management standpoint?

We had a lot of friendly communication, and whenever there was a problem, we could Skype in order to understand it. Beyond just doing what we asked for, they also made suggestions, which we sometimes went for. The best thing someone building an app can ask for is to find a team that helps improve that app, rather than just create it.

We made some changes to the general build, which extended the iOS development to two or three months. They completely respected our timelines. We tracked bugs through a file. After fixing those bugs, JatApp would send us a new build.

What did you find most impressive about them?

Their willingness to study our idea and ask questions was what made the difference to us between JatApp and other software houses we approached. Others simply asked for the project, without asking anything.

The communication was very good; they were friendly and full of ideas. We continue our collaboration and are in contact almost every day.

Are there any areas they could improve?

Based on our experience, we have nothing to complain about.

Do you have any advice for future clients of theirs?

Finding a good and functional model is a matter of luck. Our budget was big, but not huge, yet we found an amazing way to build our product. This can be different for other people, depending on the company, the ability to spend money, and finding a good partner.

The Review
Feedback summary: 

They successfully completed the app, which is still being used. They fixed development bugs quickly, offered timely progress reports, and worked well overall. There were never discrepancies over cost, and they kept a detailed script of discussions and decisions throughout the collaboration.

BACKGROUND

Introduce your business and what you do there.

I'm the COO of a company that utilizes an iOS app to help users find and connect with local businesses and services in a fast, easy way.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We needed help designing and developing our app.

SOLUTION

What was the scope of their involvement?

Before beginning app development, they assisted us with app design using a landing page concept we had created. They created the app's design concept for us. After a couple months of trading design ideas and having discussions about the app, we moved on to the development phase of the project.  

First, they created and wrote the backend from scratch. Next, they developed the iOS application itself and the admin panel for small businesses. With this function, when businesses created their company profile, it would automatically appear in the app. They implemented a geolocation feature using Google maps to indicate business locations so that users can see all the new businesses and services within a 10-mile radius around them. Users filter and search the types of services they are looking for to see which businesses best match their requirements, which are the closest, and which have the highest rating. The app also navigates the closest route to their desired location.

We try to involve as many new businesses as possible. This is partly to encourage student involvement and participation. The app is currently free to use since seed investment covered our development and some marketing. We would eventually like to redevelop our app into a white label solution and sell it to different governing entities to promote new businesses in their area. We do not work with JatApp anymore since we launched our iOS app, but instead, our own team handles development. They left us with the source code and a finished, well-done landing page. They also offered us support for around a month after launch.

What is the team composition?

One of their designers helped us with our preliminary task. When development started we worked with two of their developers. Throughout our collaboration, we also worked with a project manager from their team.

How did you come to work with JatApp?

I conducted an online search and posted our project description. At first, I was looking for freelancers. However, I ended up hiring a team, which worked out for the best because, unlike freelancers, they already knew each other and had worked together. I collected bids from various companies, and JatApp was among those who applied for our project. They offered us an estimation and showed us their previous work. We had already done the wireframes, so we decided to move forward with a trial run by using them for design. They successfully completed design work for us, so we decided to hire them for development as well.

How much have you invested with them?

We’ve spent around $50,000.

What is the status of this engagement?

We started working together in March 2017, and we finished collaborating June 2017.

RESULTS & FEEDBACK

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

The app still has users testing it out despite a period of stagnation where we almost had no users or interest. We tripled the number of users over the past six months without heavily promoting the app. I thought we would have to spend more on marketing, but news of the app spread by word of mouth. We spent some time working on another project, but now we are getting ready to implement our white labeling strategy for the app. It’s hard to measure their work’s impact through the number of users, but it may be more accurate to measure its success in changing our entire company philosophy in order to make the app a totally different product this year.

How did JatApp perform from a project management standpoint?

They were great. We communicated mostly through Skype because that was our preference. We never had any trouble during development, which we left completely in their hands. I didn't any suggestions or requests during the development process because I’m not an expert in that area. Our strategy was to let them completely develop the app and determine which technologies to apply and what it should look like, then offer feedback based on user experience. We mostly agreed on everything throughout our collaboration. They worked well, and we are still using the version of the app they developed. Any bugs the app had were all fixed during the first month.

They made me feel confident about the project, and I didn’t worry about their process. I received timely reports, so I knew how much time they worked and how much I would have to pay them. We never had issues regarding payment because they made their reporting transparent and friendly, so always knew where the money we spent was going.

What did you find most impressive about them?

They develop software well. We didn’t require complicated development work; we expected a good iOS app with solid backend work, which is what they delivered. I’m not sure if our collaboration or their work would have run differently for a more complicated process, but in our case, they did their job extremely well.

One added benefit in working with their team was that they wrote down each and every word that we discussed throughout our collaboration. Whenever they had a question, or a contradiction came up, there was always a script of our discussion to refer to.  At certain points, they even helped us identify and keep track of our own business ideas. I’ve already recommended them to other, and I have a friend who is now working with them.

Are there any areas they could improve?

No, everything was okay.

Do you have any advice for potential customers?

Make sure that you have all of your requirements in place. If you have your project written down and have a pretty clear idea of your desired end product, then they’ll help you bring your idea to life. If you have more questions than answers, don’t expect a miracle to happen. In the end, you have to be well prepared in order to have a good development team.

After a successful conference presentation, the app has active users who continue to grow in number. JetApp brought the desired level of quality for development, thanks to effective project management, time savviness, and a friendly team.

BACKGROUND

Introduce your business and what you do there.

Our service allows people to upload photos of themselves and analyze which one looks best. I'm the chief operating officer of the company.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We were looking for a vendor that could create a great design and develop our app without any delays or problems. We had strict deadlines and wanted to show it to investors.

SOLUTION

What was the scope of their involvement?

We shared feedback on our original idea, and they compared our app with others in the market. We discussed both set tasks and general items.

They developed our native application for iOS and Android, building the main prototypes and designs based on sketches we provided. Their project manager wrote the technical specs.

What is the team composition?

We worked with one project manager, one developer for each platform, and one backend developer. We also had one UI and one UX designer, as well as a salesperson.

How did you come to work with JatApp?

We researched and sent requests to different companies. We scheduled a call with JatApp, asked for an estimate, and went through several sessions. They were one of the best candidates, and we decided to proceed.

How much have you invested with them?

The project cost was around $51,500.

What is the status of this engagement?

I believe that JatApp started working with my company around November 2015. I joined the company in January 2016, after the project had started. By the end of April, we had finished the working app.

RESULTS & FEEDBACK

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

We presented the app at a conference. People liked it and we’ve gained active users. Everything's been good. Currently, our users are in the hundreds, not thousands, but we're working on this.

How did JatApp perform from a project management standpoint?

They sent us files listing our milestones, spent hours, and budget. We discussed upcoming milestones and had access to an internal documentation system. We used Trello, Slack, and Skype for communication.

What did you find most impressive about them?

They were always ready for a discussion and brought their own opinions. I also liked their design, and everything was delivered according to our timelines. The technical and sales teams were made up of pleasant people to work with.

We've referred JatApp to partners for their startup.

Are there any areas they could improve?

I liked their approach and have no additional comments.

The Review
Feedback summary: 

A flexible code architecture and a versatile approach to development will ultimately yield a more accommodating end product in regards to future iterations. JatApp continues to provide responsive project management, progress transparency, and consistent on-time delivery.

BACKGROUND

Introduce your business and what you do there.

I’m the CTO of a small startup in Slovakia. We currently have three employees, including myself.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with JatApp?

We needed developers to deliver our product.

SOLUTION

What was the scope of their involvement?

They are fully responsible for developing an iOS and Android application, including the backend.

What is the team composition?

I communicate with their project manager who manages the team.

How did you come to work with JatApp?

We did an internet search and had a pool of candidates. We decided to go with JatApp because of our initial meetings and due to their expertise. They prepared a detailed plan for us with key milestones, a video of the whole process, how much it would cost, and what the successions and risks were. They were well prepared.

How much have you invested with them?

We’ve spent $60,000.

What is the status of this engagement?

We started working together in November 2017, and the engagement is ongoing.

RESULTS & FEEDBACK

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

I’m happy with their developers. We use GitHub where I’m able to see the iOS and Android code architecture. They’ve also applied for key architecture patents, so if we need to make changes to the code, it’ll be easy to implement. The code is flexible. They follow key engineering principles.

How did JatApp perform from a project management standpoint?

We use three-week iterations in our approach after which we use incremental functionality. We decided to go with a modified version of Scrum.

In regards to communication, we have one person who contacts us and provides status updates for each iteration. They also inform us if there are any problems or if they have questions. We use Slack with dedicated channels.

We can normally reach the project manager within a few minutes. Sometimes, we generate new ideas when we receive new product builds. These ideas may even come during the middle of an iteration. We discuss all of this on Slack and receive quick responses from their team. We also have occasional Skype meetings. We don’t use a project management tool on our side, but they use Redmine as a task and bug tracker on their side.

What did you find most impressive about them?

The most important things are code and engineering quality, and both are pretty good. They fulfill the estimations they make. There are no major dropouts. Sometimes, developers create an estimation and fail to fulfill it, but JatApp delivers good code and is transparent about timing. If they can’t deliver something within the expected timeframe, they communicate it with us.

Are there any areas they could improve?

I’m happy with them.

Do you have any advice for potential customers?

They’re a flexible team who can work on different projects. We’re a startup, but their approach is versatile and allows them to adjust to different challenges, especially in the mobile domain. Future clients need to share their problems and expectations. The JatApp team is quite proactive. They will ask questions if they need clarification on anything. They might say “no” to some things, but they have a good approach.
