BACKGROUND

Introduce your business and what you do there.

I am the CEO of a startup. We develop a mobile application that enables users to invest in alternative assets.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Corner Case Technologies?

We had our initial concept, but it was important for us to develop an MVP so we could test and validate our assumptions with real users.

SOLUTION

What was the scope of their involvement?

We had a concept in mind, but Corner Case Technologies helped us build the application from scratch. They used React Native to develop the frontend and Django to develop the backend in an SQL database. They’ve delivered the app, which is compatible with iOS and Android.

Since delivering the MVP, we’ve moved from a fixed price contract to a time and material contract. Corner Case Technologies has allocated a team that we work with on continued developments to improve the app. The team also helps us with maintenance, tracking, reporting, and issue management.  

What is the team composition?

We work with five team members, including two frontend developers, two backend developers, and a UX developer.

How did you come to work with Corner Case Technologies? 

We conducted market research and interviewed different agencies around Europe; we decided to partner with Corner Case Technologies to build the MVP. 

How much have you invested with them?

We invested roughly €50,000 (approximately $52,000 USD) for the initial MVP. Since then, we’ve invested an additional €80,000–€90,000 (approximately $82,000–$93,000 USD) in time and material costs. 

Our total investment has been about €140,000 (approximately $144,000 USD). 

What is the status of this engagement?

We began working with Corner Case Technologies in April 2021, they finalized the MVP in July 2021, and the partnership is ongoing.

RESULTS & FEEDBACK

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

Our main metrics for the MVP were the delivery time and the quality of features, both of which Corner Case Technologies met.

How did Corner Case Technologies perform from a project management standpoint?

Corner Case Technologies consistently met deadlines for deliverables and charged us the agreed-upon cost for the project. We use Jira to manage tasks and communicate via Slack. 

What did you find most impressive about them?

We’ve been most impressed with the expertise Corner Case Technologies brings to the table. They challenge our assumptions and strive to understand our needs rather than just accepting them.

Corner Case Technologies tries to solve user problems in the most logical way possible. They present us with alternative features that provide equal value but fewer development complexities. Their desire to provide effective, efficient solutions sets them apart from their competitors.

Are there any areas they could improve?

Corner Case Technologies could improve their methods when managing teams independently of the client. We worked with their product owner and project manager early in the project, but the process wasn’t flowing, so we hired our own staff to fill those roles. Our staff coordinates the project and manages the remote team, which has worked well. 

Do you have any advice for potential customers?

I recommend starting the project with a fixed price contract for a clearly defined deliverable so that you can avoid any cost discrepancies. Then, if you’re happy with the work, evolve the relationship to incorporate a time and material contract for continued development efforts.

BACKGROUND

Introduce your business and what you do there.

I’m the founder of PropertyMatch, a site that serves as a marketplace connecting property owners and seekers. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Corner Case Technologies?

I needed a firm to take my vision and transform it into a functional website. 

SOLUTION

What was the scope of their involvement?

Corner Case Technologies has designed and developed my website from scratch using Python. I’ve provided their team with my idea for the site, and Corner Case Technologies has taken it from there. Their team has put together the site’s color scheme and developed the mockups and wireframes. 

What is the team composition?

I’ve worked with several teammates from Corner Case Technologies throughout the project, including a designer, back- and frontend developers, and an account manager. 

How did you come to work with Corner Case Technologies?

I contacted several companies, but ended up hiring Corner Case Technologies because of their professionalism and price. They could match my budget, although we did scale down the project. 

What is the status of this engagement?

Our engagement began in August 2021, and it’s ongoing. 

RESULTS & FEEDBACK

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

The website launched in early January 2022, and although there have been a few bugs, everything is running well. I’m using Hotjar to monitor user navigation, and from what I see, everything is going well. The site is very easy to navigate. 

How did Corner Case Technologies perform from a project management standpoint?

Occasionally, I need to remind Corner Case Technologies’ team about project pieces, but they always meet my deadlines. We communicate through email and Google Meet. 

What did you find most impressive about them?

I’m really impressed with Corner Case Technologies’ quality of work — the end product they’ve delivered works really well and is a positive force for my business. 

Are there any areas they could improve?

I think Corner Case Technologies could improve their communication; sometimes, I was left in the dark about project aspects. Corner Case Technologies should implement a bug and progress tracking system that their customers can access. 

Do you have any advice for potential customers?

I’d advise customers to communicate clearly with Corner Case Technologies. For example, I send them bulleted lists of what I want them to do so it is easy to comprehend. 

BACKGROUND

Please describe your company and your position there.

We are a digital cashflow management platform

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Corner Case Technologies, and what were your goals?

We wanted to build in few months an MVP to get our first customers, validate product-market fit and iterate on user experience to make the product something that delivers value and can be monetized.

SOLUTION

How did you select this vendor and what were the deciding factors?

Referral from our venture investors.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

CCT helped us in setting up proper development practices, robust ci/cd and infrastructure. Also, it helped us with improving features already existing and extending the scope of our product building new features. They use modern JS stack (React.js, Node.js), mostly for front-end, while for backend, they're very strong and experienced Python developers (Flask/Django). They're very much at ease with AWS.

How many people from the vendor's team worked with you, and what were their positions?

3-4 people, 1 frontender, 2-3 backenders.

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

After we started working together, we started shipping a product that delivers 80% WAU/MAU and 35% DAU/WAU. Product has great engagement and retention.

Describe their project management style, including communication tools and timeliness.

They're very professional, clean, strong in both technology and work ethic. They adapted to our stack, so we use Google, Slack, Jira for project management and communication.

What did you find most impressive or unique about this company?

Strong work ethic, pragmatic, no frills. They're great professionals with a robust background and who are always happy to help.

Are there any areas for improvement or something they could have done differently?

Honestly, given the pace of our development and rollout, no glitches. We are very very happy to work with them.

BACKGROUND

Introduce your business and what you do there.

Headlight is a startup that offers personal coaching services. We were established three years ago with around 10 full-time employees. I am in charge of overseeing our product and I look after anything technical regarding the application that we and our customers use.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Corner Case Technologies?

Shortly after I joined the company as the head of product, the freelance software developer that they had hired decided to move on to other projects. I was looking to hire an internal software developer who could help us build on the then-current version of our MVP. I decided to outsource that role to Corner Case.

SOLUTION

What was the scope of their involvement?

Corner Case provides us with full-stack developers who could do mobile app development using React Native and handle all of the backend services powering that iOS and Android applications. We are delivering online coaching services for business professionals, and their team supports the calendar functions in the backend of our app. 

Corner Case also handles the web portals and web services that our coaches need to access to provide the service. We have internal CRM systems, participant management systems, and analytics tools that are powered by APIs and all deployed on AWS, and their team helps us with all of those as well. 

We’re also using Corner Case on an ad-hoc basis. When we need to do some UI design, they work with our internal graphic designer on some of the visual elements of the application. I knew, before hiring them, that we would be exploring new avenues and adding new features to the app, so it was important for me that Corner Case offered some design services as well. 

Apart from those, Corner Case also conducts QA testing on all of the codes that they deliver to us. They do manual testing to look into not just the code quality but also the experience quality. However, we recently decided to take on this process ourselves as we need to involve the coaches in the QA. In this regard, we are using not using their QA services in-depth. 

What is the team composition?

We currently have one full-time employee who is in charge of all mobile app development. Depending on the load, we also have a senior backend specialist. I believe they are involving a team of frontend experts as well, but that is invisible to us. In total, there may be around four people working on this project, but we’re only paying for the services of the members with whom we’re in constant communication. 

How did you come to work with Corner Case Technologies?

We’re part of a studio that helps startups like us grow. When I was looking for external companies that could help with software development, the CTO of the startup studio recommended Corner Case. He had worked with the agency before and was very impressed with their services.

I’ve worked with other offshore companies in the past, so it was easy for me to make a comparison. We liked that Corner Case had the experience of working with a startup like ours where there won’t be enough people to manage the partnership. Their experience just aligned with our way of working, so we decided to go with them.

How much have you invested with them?

At this point, we’re a bit above the €60,000 (approximately $67,000 USD) mark. We pay between €10,000–€15,000 (approximately $11,000–$17,000 USD) a month. 

What is the status of this engagement?

We kicked off the project in August 2021, and it is ongoing. 

RESULTS & FEEDBACK

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

Corner Case has been able to work much more quickly than the last freelancer we were engaged with. What would’ve taken almost a month and progressed very slowly has only taken Corner Case two weeks to accomplish. The quality of their output is much higher, as well. I feel confident that what they produce is something that I could put in the hands of our clients. Compared to before, we’ve had a three-fold increase in our work velocity. 

How did Corner Case Technologies perform from a project management standpoint?

Corner Case is very flexible. All of our discussions are open and transparent. We have a lot of well-established day-to-day processes, and we work in an agile manner. However, we’re still in the process of refining our partnership. As we grow larger, we might move towards a more standardized sprint or scrum schedule. 

Their team is very self-sufficient. We simply agree on priorities, and they would take it from there. Their seniority and expertise give me the confidence to let them take over the development. I don’t need to go into too much detail about every requirement; they can figure it out themselves.

We communicate over a shared Slack channel and use Jira to coordinate our different activities and priorities. 

What did you find most impressive about them?

Compared to other offshoring companies, the ratio of their price to the quality of their work is very much at the top. They deliver with excellent speed and are highly innovative, which is helpful for a company of our size. 

Are there any areas they could improve?

No, they’ve been great since day one. There has been only one instance when we needed to double-check something because of the quality, but that was more on us and not them. 

Do you have any advice for potential customers?

Corner Case is very well versed in working in an agile manner, so if you’re looking to do frequent iterations and establish constant feedback loops, they’re the company for you. I’m not sure how they will fare with being onboarded into a large company’s established internal processes, but it will do you good to listen to their ideas and perspectives because they have the ability to come up with their own ideas.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Corner Case Technologies?

Corner Case Technologies were hired to develop the MVP of the product.

What were your goals for this project?

Project goal was to have working MVP of the app with couple external data integrations, data visualizations, user registration and onboarding process. It was important to setup the framework for the frontend and backend for later development process.

We wanted to engage beta-testers as soon as possible also to apply to Y Combinator Summer 2021 program. Time period was just two weeks.

SOLUTION

How did you select Corner Case Technologies?

We know Corner Case Technologies from the personal network. They have very strong recommendations. We talked with other companies, but CCT demonstrated solid competence and desire to execute in very short time.

Describe the project in detail.

Project scope was to have an app with two external data integrations over APIs, data visualizations, and users onboarding process. We prepared basic wireframes and guidelines. CCT created all dev-op processes and cloud setups.

iOS app was developed with React Native, backend with Django framework. We worked very closely with their team and project was executed very effectively.

What was the team composition?

We worked with one frontend and one backend developer. Also CTO of Corner Case Technologies helped us strongly on finding tech solutions and with project management.

RESULTS & FEEDBACK

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

Just in week After MVP launch we had 120 members on waiting list. First testers gave positive feedbacks.

How effective was the workflow between your team and theirs?

We worked very closely. We had daily standup meetings. All questions and problems was solved very fast and effectively.

What did you find most impressive about this company?

Their knowledges and experiences are impressive. Also they're willing to go the extra mile to make the customer happy.

Are there any areas for improvement?

I think, we could work together even faster if the project would take longer period of time. Development speed was growing with each day.

GlobeTrott travel is a travel start-up. Our vision is to make exploring new destinations easier, by curating personalized audio tours and a platform from trip planning. I am the Founder and the CEO of GlobeTrott Travel.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Corner Case Technologies, and what were your goals?

Corner Case Technologies were hired to develop the MVP and V1 of the product. The initial conversation took place when the product was at the idea stage, so the team not only developed the product but have also provided guidance and consultancy along the way we were identifying the needed features, UX, UI and the overall user journey.

SOLUTION

How did you select Corner Case Technologies and what were the deciding factors?

The development of the product was discussed with 3 different companies, all of whom came with strong recommendations. Key criteria for choosing the development partner were:

• Approach from the supplier
• are they going to deliver exactly what is asked or will they share feedback and recommendations from their experience
• Experience in building mobile apps
• Price and time (how long will it take to develop)
• Does the team believe in the product It was clear that Corner Case Technology is the preferred partner after the first few meetings.

They have asked many questions and sent me back to do additional research, so that the product that will be developed would really meet the market needs. The team was interested not only to win the project, but to ensure that they really deliver value and create a strong MVP.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

I have met Corner Case Technologies at the time when the business idea was still being validated to understand how much the initial development costs would be. During the meeting, I have received a list of information that I need to provide, so that they could start the development.

A rough estimate on how much it would cost to develop the prototype based on initial wireframes was provided, though I was strongly encouraged to work with UX & UI designers first and get the project requoted once the scope has been very clearly clarified. Once a clear user journey within the mobile app and the wireframes have been agreed upon, a quote has been provided.

After signing the agreement the kick-off meeting was with the project manager. Discussed all of the information that they already had (scope, market research), next steps of information that were needed, who is the team, how we will be communicating, etc.

Each meeting with the team members very well structures, followed by the next steps - that have always been delivered on time. Throughout the product development, the PM has been forthcoming with questions, which meant they were resolved quickly and no assumptions were made.

During the duration of the project, the team have provided consultancy services at the initial set-up stages and development once the scope has been confirmed.

How many people from the vendor's team worked with you, and what were their positions?

9 people Project Manager UI Designer CTO CPO COO Developers

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

The product was delivered on time and working with Corner Case Team has been a real pleasure. I was able to share updated wire frames with target customer thought the process to conduct the needed research. The product has not been launch to the market yet, as the content side (Corner Case are not responsible for this deliverable) is not complete.

Describe their project management style, including communication tools and timelines.

We had a weekly meeting that was lead by PM. Project updates were shared and any questions were answered. Clear meeting minutes, next steps and timelines were communicated after every meeting.

During the kick-off meeting clear communications and responsibilities were allocated, so right away everyone knew their responsibilities and scope for decision making. Used a mix of Slack and E-mail for communications.

What did you find most impressive or unique about this company?

Their willingness to go the extra mile and asking questions. For me it was very clear that they want to build good product and not only write some code based on clients requirements. The communication was always very clear and everything was delivered within the agreed timelines.

Are there any areas for improvement or something they could have done differently?

Very happy with the experience and I highly recommend them! Initially some meetings were quite lengthy, as the team have not only asked questions, but also shared opinions on how the problem could be solved in several different ways.

I would have liked the meetings to have been shorter, though the insights that have been shared were invaluable, so it was really good that the team was so willing to share their expertise.
