Interexy

BACKGROUND

Please describe your company and your position there.

Labster is a company dedicated to developing fully interactive advanced lab simulations for school and college/university students. We combine these with gamification elements such as an immersive 3D universe, storytelling and a scoring system which stimulates students’ natural curiosity and highlights the connection between science and the real world.

I am the mobile app Project Lead, and have been working with Interexy developers to create a wonderful product for our audience.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Interexy LLC?

We required the services of an expert company to supply us with their best talent for backend development and quality assurance requirements. The backend development required NodeJS and CMS expertise. The quality assurance required great attention to detail, manual functional and user interface testing.

What were your goals for this project?

To launch the product on time with the best resources working on a high-quality product.

SOLUTION

How did you select Interexy LLC?

We selected them via a third party platform and hired them after a few interviews and portfolio review.

Describe the project in detail.

Labster mobile app required to have an Android interface for fully interactive advanced lab simulations along with multiple other activities like quizzes, leaderboard, etc. The backend was handled by Interexy experts, and they created high-quality APIs with NodeJS as per our product requirements after careful consideration.

What was the team composition?

1 Backend Developer with NodeJs and CMS expertise 1 QA with manual testing skills

RESULTS & FEEDBACK

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

A very high-quality product functioning overall implies hard work done in QA. The product is being developed in a very dynamic and scalable way so that we can easily pivot from our MVP. The backend developer has worked very hard on it.

How effective was the workflow between your team and theirs?

Very smooth communication and workflow management. Daily scrums, Sprint planning, use of proper tools ensured that no one was left out of the loop and that the entire team, even remotely distributed, stayed super focused.

What did you find most impressive about this company?

A dedicated project manager/account manager was allocated to us free of cost, even when we never asked. We were always kept updated about the progress very transparently. Even though there were no hiccups, the account manager was always there to support us.

Are there any areas for improvement?

The onboarding can be made smoother, where we can have more communication about the requirements, expectations, etc. Everything else has been perfect and the quality of work is superb.

BACKGROUND

Please describe your company and your position there.

I am the Co-Founder and CTO of a start-up called Scout (Scout It Now, LLC). Scout partners with employers and employee benefits aggregators as a critical addition to their current wellness and childcare programs, providing employees with a simple way to engage and enrich their kids' lives so they can be more productive at work.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire AMS LLC, and what were your goals?

We wanted to build an app that would make discovering and managing kids activities as simple as it should be, so parents could focus on other more important things. We needed to work with a company that could take our idea and wireframes drawn on napkins and turn it into a real functioning app for iOS and Android.

SOLUTION

How did you select AMS LLC and what were the deciding factors?

We knew we wanted to use Upworks to find the initial development team, and Stan Sakharchuk and his AMS LLC team had very high reviews and great feedback on that site. After interviewing a few different businesses, we knew that AMS LLC would be the best team to work with to help build out our new app.

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

We have worked very closely and collaboratively with AMS LLC right from the start. Our project manager kicked our relationship off with a meeting to meet the team and go over our objectives. We worked with their UX team to come up designs for the app, and once the designs were finalized they began app development for iOS, with the Android app to follow after. I believe that the most successful projects are those where the teams check in regularly, and Stan and his team made that easy. We had regular check-ins over zoom and skype, so I always knew where each project was at any given time.

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

A project manager was the main point of contact. We also interacted with the UX lead to help come up with mobile designs.

RESULTS & FEEDBACK

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

Scout partners with employers and employee benefits aggregators as a critical addition to their current wellness and childcare programs, providing employees with a simple way to engage and enrich their kids' lives so they can be more productive at work. We launched in early July and have started to see a lot of traction in the Boston area. We recently closed deals with two fortune 500 companies with 10s of thousands of employees who have access to the Scout app on both iOS and Android.

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

Project manager is very involved and gives regular updates to keep everyone updated. I would get regular updates via skype or calls, and we were always in constant communication. Even with the time change, I never felt like it was hard to touch base with the project manager.

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

I'm most impressed with how hard working they are. Working in a start-up, things need to move fast. We needed these new apps quickly and AMS LLC delivered on all of that. The quality of their work is great and we have been very happy with everything they have delivered. We currently have an ongoing contract for additional dev work with them and will continue to use them for our development work.

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

Honestly, I can't think of any. Like with any development project, communication is key. Whenever I had a concern, it was immediately addressed. We are extremely happy with them and have already recommended them to other businesses.

BACKGROUND

Please describe your company and your position there.

I am the CEO of a travel-tech startup in London. At the moment we only have a couple of employees.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire AMS LLC?

We wanted to build a Beta of a travel application with which we could approach investors and raise capital to build out a full, more detailed version.

What were your goals for this project?

We wanted a fully functional application that displayed its unique features.

SOLUTION

How did you select this vendor?

We sent out a job description on a freelance website and, following a short hiring process, made the decision to bring their team onboard.

Describe the project in detail.

Once the project began, we had a series of calls to discuss the overall structure of the application. This was followed by months of detailed changes to get the product into a suitable shape.

What was the team composition?

Originally we spoke with a senior member of the team in the introductory stage. We were then assigned a project manager for the duration of the work, with whom we've had constant direct contact.

RESULTS & FEEDBACK

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

The Beta was built in the space of around 5-6 months. It's very impressive, easy to use, and achieves its primary purpose.

How effective was the workflow between your team and theirs?

The project manager has been very easy to contact and has answered all our questions in detail.

What did you find most impressive about this company?

The quality of the product and the speed with which the application was coded were impressive. So was the rapid communication between their team and ours.

Are there any areas for improvement?

None.

BACKGROUND

Please describe your company and your position there.

Crumb is a mobile app that motivates people to be more active. Users gain points for each natural movement like steps or stairs and can use these points to get special offers in our shop. I am the CEO at Crumb and also overseeing technical implementation.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire AMS LLC?

We hired AMS LLC to build both our mobile apps for Android and iOS in native development Java and Swift respectively.

What were your goals for this project?

The goal of the project was to build the first MVP for our company from scratch from the designs that we'd built in a very short time to convince investors for a financial round.

SOLUTION

How did you select this vendor?

We got introduced to AMS through Linkedin and their short time estimation and positive helpful attitude was the reason why we chose AMS.

Describe the project in detail.

The project was to build the mobile app for http://crumbup.com/ which is a mix of a fitness, finance and eCommerce app. It needed to

1. Connect with health data to record user steps and movement.
2. Reward users with a currency for that movement and keep a track of their balance
3. Have a shop where users can buy product offers with that currency.

We had daily meetings with AMS to discuss the best possible solution and in the end the goal was to set up

1. Backend in Firebase
2. Analytics of user behaviour from google analytics and bigQuery
3. Swift and Java for mobile app development

We provided the design in adobe XD and that was all that was required from us to give. The rest was all handled by AMS.

What was the team composition?

We were assigned a project manager, an iOS developer, an android developer and a QA and whenever the deadlines was getting tough to meet AMS even added extra developers to make sure that we reach the deadlines.

RESULTS & FEEDBACK

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

Within 9 weeks of launch we were able to get 8 thousand users and 300 ratings with an average of 4.7 stars. Almost no bugs with the app and the app looking exactly like the designs that we provided. The app is currently available in selected countries but can be found here https://apps.apple.com/de/app/crumb/id1455844646

We ended up with a beautiful product that has a less than 0.5% crash rate and has allowed us to expand in multiple countries. Also due to their experience they were even able to suggest us features that we should add in our app that would make it even better.

How effective was the workflow between your team and theirs?

We used Skype and daily standups to maintain communication. People from AMS were always available and were super quick to respond to any issues that we had. Speak great English and we almost never felt that they were working remote due to them being always available.

What did you find most impressive about this company?

Their experience in mobile app development is truly remarkable. They're super fast at coming out with new features and building stable apps on technology that can scale very fast. They're also very considerate to changing needs and welcome changes in plans.

Are there any areas for improvement?

We've been overall extremely happy with AMS but more automated testing could have helped us catch bugs even faster.

BACKGROUND

Please describe your company and your position there.

We are a digital agency focused on conversion rate optimization based in Japan but we service clients globally. I'm the co-founder.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire AMS LLC?

We were looking for a reliable & experienced team of mobile developers to assist in the huge project for one of our UK-based clients. We were doubting about hiring even a nearshore partner for this job due to bad experiences in the past, but after speaking with the AMS Team, we were confident that they could deliver.

What were your goals for this project?

Develop high-quality development solutions for our client since it was the first project of that size with them. It was crucially important to perform everything to an high level of standard to establish relationships & more referral business in the future.

SOLUTION

How did you select this vendor?

From our network. They had clients in the UK that they had worked with in the past & they were referred to us as being professional developers. We started hiring process speaking with different suppliers in the region, but AMS turned out to be the best since they are highly specialized in mobile development whereas other agencies offer a whole range of various services.

Describe the project and the services they provided in detail.

They developed UI/UX & native iOS and Android versions for the app. They started with SRS for the mobile part of the project, outlining functions, designs & user stories. Then, using Scrum approach with weekly sprints, they started working on the project providing us with weekly updates of the software & were in constant communication with us by providing better approaches to develop new functions - to be honest, we were really excited by their proficiency in mobile development & the quality of the solutions they provided.

What was the team composition?

They had a project manager, native iOS Developer, native Android Developer, UI/UX designer & QA person working with us. We also had the feeling that it wasn't the first time they worked together since they were solving complex issues smoothly & we felt that the mobile part of the project was in good hands at all times.

RESULTS & FEEDBACK

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

Well, it was awesome. Together we’ve delivered a full-stack solution on time, our client was very happy and now we are negotiating on 3 new deals of that size since we’ve proved we can deliver complex products at a high level of quality & meeting deadlines. Our business is growing and we're looking forward to future projects with them. 

How was project management arranged and how effective was it?

It was impressive. After building SRS we saw a clear sprints structure for weeks to come, tasks that needed to be finished, possible blockers, estimations, etc. At each moment, we clearly knew what the guys are working on and what we would get at the end of next sprint. It was awesome, especially comparing to other agencies we’ve worked with.

What did you find most impressive about this company?

Processes & mobile expertise. We really felt like we are working with professionals & don’t even need to do things from our side - no micromanagement, meeting deadlines, clean & clear development process. Mobile expertise, UI/UX & consulting skills are also on a high level - it might be hard for web developers to dive into these things, but when you have someone so experienced onboard you can really build awesome products.

Are there any areas for improvement?

There is always something to improve in any activity. Communication from the web part might be the one when working with these guys, but there were certain issues with providing an accurate API guide from our side too, so I can’t really blame anyone for that. The problem solving is definitely decent here.

What was the team composition?

It was a project manager from their side working on the project, handling communication & accountability part (we had Jira as a project management tool), iOS developer & UI/UX designer.

From the start we had a strong feeling that they were working in the team, not the first time, processes were in place and it was a pleasure to communicate & work with the guys.

RESULTS & FEEDBACK

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

The impact of this project is tremendous. The client of ours is a multiple business owner in the US and with this application done perfectly we are currently negotiating second web-based deal with 7 developers, QA person, project manager & business analyst - we are very happy we were able to build this relationship & grateful for AMS for helping us!

How effective was the workflow between your team and theirs?

Project management was handled via Jira, with an experienced project manager with a technical background controlling the whole process. At each given moment during the whole development, we knew what is the task developer is working on, what kind of blockers he has & the current milestone completion.

What did you find most impressive about this company?

High professionalism & expertise in native mobile development & designing, these guys really know what are they talking about and sincerely love phones & applications, we were smashed with the amount of value we got on a first consultation call with them.

Are there any areas for improvement?

We had a couple of blockers during product development, but their team was able to solve them on time with a professional problem-solving attitude. I can’t think of anything they should improve currently, our experience was flawless.

How many teammates from Interexy were assigned to this project?

2-5 Employees

Describe the scope of work in detail. Please include a summary of key deliverables.

We’ve been working with this team on the build of a fairly complex platform in the health and care space, involving multi-sided workflows, compliance considerations, and a high degree of operational nuance. From the outset, they demonstrated a strong ability to understand not just what we were asking for, but why , which is rare. 

They’ve consistently translated high-level concepts into well-structured, scalable technical solutions without overcomplicating the delivery. What’s stood out most is their ability to operate at both a strategic and execution level. They’ve contributed to shaping core product decisions, challenged assumptions where needed, and brought forward better ways of structuring workflows and architecture. 

At the same time, they’ve maintained solid delivery momentum and kept things moving. Communication has been clear and consistent throughout. We’ve had good visibility over progress, risks, and trade-offs, which is critical given the pace we’re operating at. They’re also pragmatic. In a startup environment where priorities shift and not everything is perfectly defined, they’ve adapted quickly without losing sight of the overall system integrity. 

Overall, they feel less like an outsourced development team and more like an extension of our internal product function. What did the vendor do well? Strong product thinking, clear communication, and the ability to handle complex, real-world workflows without unnecessary friction. 

They bring structure to ambiguity and maintain momentum. What could be improved? Like any fast-moving build, there are always areas where timelines can tighten under shifting priorities. That said, they’ve been responsive and proactive in managing this when it arises. Overall rating: 9/10

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

The project has delivered clear, tangible progress across both product development and operational readiness. • We successfully moved from early concept to a fully functional, production-ready platform, covering the full case lifecycle from referral through to reporting and billing. 

• Core workflows that were previously manual or fragmented are now structured and systemised, significantly improving consistency and reducing operational overhead. 

• We’ve established a scalable architecture that supports multi-stakeholder use (case managers, providers, and funders), positioning us to onboard new users without reworking the core system. 

• Development velocity has been strong, with regular feature releases and iterative improvements based on live testing and feedback. 

• We’ve reduced reliance on multiple third-party tools by consolidating functionality into a single operating platform, improving visibility and control. 

• The platform is now in a position to support commercial rollout, with key modules (case management, reviews, reporting, and financial tracking) fully operational. 

Beyond the technical delivery, one of the most important outcomes has been clarity. We now have a structured, end-to-end system that reflects how the service actually needs to operate in the real world, which is critical for scaling.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Their project management has been structured, transparent, and well-suited to a fast-moving product environment. They’ve worked in an iterative, sprint-based approach, which has allowed us to maintain momentum while continuously refining the product. We’ve had clear visibility over what’s being worked on, what’s coming next, and where any risks or dependencies sit. In terms of delivery, timelines have generally been met, particularly given the complexity of the platform and the evolving nature of requirements. Where priorities have shifted or new requirements have emerged, they’ve been pragmatic and responsive, adjusting plans without losing overall progress. Communication has been a strong point. They’ve been proactive in flagging blockers, proposing solutions, and keeping us updated throughout. There’s been a consistent feedback loop, which has made collaboration straightforward and reduced friction. They’ve also responded well to our needs as a client. In a startup context where things aren’t always fully defined, they’ve shown flexibility and a willingness to adapt quickly, while still maintaining structure and discipline in delivery. Overall, they strike a good balance between being organised and being adaptable, which is exactly what’s needed for this type of build.

What was your primary form of communication with Interexy?

Virtual Meeting

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

What stood out most was their ability to genuinely think at a product level, not just execute tasks. A lot of development teams will build exactly what you ask for, even when it’s flawed. This team consistently engaged with the underlying problem, challenged assumptions, and helped shape better solutions. That level of ownership is rare. They also have a strong grasp of real-world operational complexity. This wasn’t a simple build, it involved multi-stakeholder workflows, compliance considerations, and edge cases that don’t show up in clean specs. They were able to absorb that complexity quickly and translate it into a system that actually works in practice. Another differentiator is how they balance speed with structure. They move quickly, but not in a way that creates technical debt or short-term thinking. There’s a clear focus on building something scalable and maintainable from the outset. Overall, they don’t operate like a typical outsourced dev team. They think and behave more like an embedded product and engineering function, which has made a significant difference to the quality of the end result.

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