We appreciate the proactivity and flexibility shown by Atta Systems
suffering from digestive health problems. Patients have access to personalized care pathways
that cover every need from diagnostic to chronic or acute management.
Together with Atta, we set out to develop the whole technical infrastructure, including:
the backend built on top of AWS cloud services and infrastructure
the patient web app
the patient mobile app (for iOS and Android)
the clinician web app
the administration management interface
Atta managed the whole process of development, kept us informed and in the loop.
What makes Atta stand out is a great mix of incredibly knowledgeable engineers and domain
expertise (healthcare) that allows them to understand the audience of their products.
Working with Atta was really easy, we recommend working with them.

One truly visionary tech company - highly recommend
One of our client contracted us to develop a mobile app that connects your phone to your car computer and gathers some specific information in order to predict recurrent behaviour of each driver. After a selection of 3 software companies, we decided to hire AB4 Systems for the technical and development part of the app. AB4 Systems has a lot of expertise in the AI software programming and their approach mixed with our design thinking process was the perfect team for the project.
What we can underline is the flowless communication and building together on each idea that came up during the development. Their project manager had very good communication skills and understood all the challenges of the app.
Very proactive and innovative team.

patients suffering from IBS. We already had the app live when we engaged with
Atta.
Our app needed quite a bit of performance improvements as well as
improvements on the user flows available within the app. We needed React
Native experts that could takle our challenges.
Atta has amazing tehnical expertise. Then, they also have extensive domain
expertise (healthcare).
After we started working together, we also learned that they have a really high
level of empathy for their customers. They try to understand our struggles, our
problems and always adapt. They are also great communicators, they
encourage their whole team to communicate with us to make the feedback loop
shorted during the development cycle.
They are fast, they deliver amazing quality. Highly recommend.

Atta Systems Executive Interview

My role in the company is to facilitate growth. We grow on several dimensions - we grow professionally as a team, grow our customer base, and grow our team. We are inspired by great companies like Google, Facebook, Spotify that managed to grow while maintaining amazing service delivery standards.
Our team consists of hand-picked thoughtful professionals. We have product managers, product designers, software engineers, Q&A engineers, and product marketing specialists. We put a lot of effort into recruiting the smartest and brightest people out there. We look for interesting personalities that would complement well with us.
This impacts the way we communicate internally, how we do project management, and how we formulate each and every task. It creates an enormous amount of value for our clients.
Most of our customers stay with us after we start working together. UNICEF has been working with us for five years now, Medicai has been working with us for the last three years, and we have other examples too. Right now, we have 60% repetitive customers and 40% new customers. We have been focusing on growing our customer base in the last year.
We start the analysis from the target market and the problem that the app wants to solve. We then create a list of functionalities, and from there, we estimate what is needed technically to achieve it.
We have very productive frontend technologies like React Native and Flutter now for the frontends and really fast to deploy and easy-to-use Backend-as-a-Service technologies like Firebase or Parse Server that make it really easy to develop small to medium-sized apps.
The Hybrid approach is amazing, especially for utility apps; it offers amazing advantages like a single codebase for both operating systems, smaller maintenance costs, faster development.
Native, on the other hand, offers you the opportunity to make the UI of your mobile apps really shine and take full advantage of the hardware platforms. It works really well for games, immersive experiences. It is also a good idea to go for Native if you hope to be showcased by Apple or Google on their app stores.
The first discussion is Hybrid (React Native or Flutter would be my go-to choices now) vs. Native (iOS and Android). I would choose a Hybrid approach for utility apps. You gain so much by going Hybrid- smaller codebase, fewer bugs, better maintainability. I would go for Native if marketing on App Store/Google Play is a must, and the end-user experience needs to be amazing, needs to stand out. Types of apps would be games, immersive experiences, experiences that need to interact well with the hardware or the low-level SDK’s of the operating systems.
- Size of the technical problem: users that the app addresses, other data that impacts the dimension of the problem
- The complexity of the user flows
- Integration with other systems
2019: Smallest projects were $10,000. The largest project was $200,000.
It seems that the subscription model really caught up in the last couple of years. If done right and if it makes sense, it is really powerful from a business perspective.
