It all started with a beer with the amazing creative people from AB4. We were talking about how to improve the engagement we have with our community. Fast forward a couple of months... and the VRTW apps make it really easy for our listeners to get in touch with our music in-between events.

I’ve worked with AB4 Systems for 6 years on a number of projects and they have always delivered impeccably and on time. They are great professionals and a pleasure to work with.

As an owner of a group medical practice, I have had the opportunity to work with many businesses, not only in my area, but throughout the world. My experience with many of them have strictly been about Money, Contracts, Legal matters, and basically just ‘Business’. I recently had the opportunity to work on Nutrient IQ with AB4 Systems and my experience with this team has been Spectacular to say the least. What separates AB4 from the rest is that their primary focus from day One was always on THE RELATIONSHIP with their clients. From our initial meeting until completion of the project I was treated like family, was delivered on their promises, and most importantly when the unexpected occurred (on my end) they went above & beyond to find a creative solution. It’s the little things that makes this group stand out from many others I’ve worked with in the past.

We made a great team with AB4 working at SkinVision. They understood the research requirement and complications and helped us integrate our work in the SkinVision mobile apps with ease. I highly recommend them, they are a team of doers and creators.

Great team, great vision. Fully involved in the process of developing and publishing a mobile product.

We have an amazing collaboration with AB4 Systems. They took the software product responsibility in their own hands and made sure they deliver a great experience to our users. VRTW community members are in love with the apps and listen our music all day long through the mobile apps/voice assistants/smart speakers. We highly recommend anyone to start working with AB4 Systems asap! They are the best!

We contacted AB4 Systems in order to build an invoicing app for freelancers, we did something ourselves, but we blocked and tried to find somebody with experience in building apps, like this we've arrived at AB4, and I don't regret it, they have an awesome team and helps us to launch the app in just a couple of months. I will recommend them anytime, aside from our contract they came with advising.

We worked with AB4 Systems to develop an IT solution within a pilot project for case management, real-time monitoring, and data processing and reporting to be used by community professionals and county level specialists working in the public sector, starting from the needs identified in the field and evidence generated by studies and research. The IT solution has two main components: i) a mobile application that is used by community workers in their field work and contains an interview guide for collecting data on all the members of a household, generates a diagnostic of the household children’s and women’s vulnerabilities, and suggests a list of basic services, while providing users with a powerful case management tool; ii) a web-based platform, which provides data aggregation at local, county and national levels and generates reports for activity monitoring and evaluation purposes or in support of interventions, projects, policies etc. AB4 Systems provided adequate support in ensuring system integration and, based on the needs of the project, in integration with a Business Analytics platform. The process of integration with the BA platform was a major milestone in the development and testing of the product, allowing data analysis and generating data visualization. The AB4 Systems team is great, with highly professional, passionate and motivated software engineers. They always tried to achieve high results. Our collaboration was smooth and easy as the team always works to anticipate the needs and to pro-actively respond. There were situations with a huge load of work, in a very short period of time, and they were responsive and delivered in a timely manner, doing the extra mile effort that needed to be done. Working in the social sector, with a pilot project approach, the costs were always a key aspect, as we needed to develop an IT solution while using the most efficient and effective solutions. AB4 Systems’s team has always recommended open-source frameworks, whenever available and otherwise presented us with options presenting the pros and cons for various solutions. During our collaboration, the team was very responsive and our communication was always smooth and easy. They do their best to adapt to the needs of the client, while always having an eye on the end-user. Working with AB4 Systems was a very good experience for development of quality software, ensuring all stages of software development process including definition, design, coding, code control and reviews, testing, release management and product integration.

We turned to AB4 Systems for a project concerning one of our large retail clients who is in need of a discount management platform. The request was to build an initial PoC based on some specifics, which the guys from AB4 Systems delivered after only two sessions with them, one of which focused on UI/UX. Needles to say that based on my experience, I definitely recommend working with them, for both their friendly approach and efficient communication, as well as for their world-class experience and outstanding technical skills. Also, they serve one mean coffee at their HQ.

I can think of no better team to work with when it comes to product development. The support AB4 gave us through the last year was game changing for Medicai. They are not contractors, they are part of our team. We rely on their judgement for our most complicated decisions with regard to the product.
