Atta Systems (formerly AB4 Systems)

Great communication with the developer. Great level of flexibility

The agency took over an iOS app which had started to be developed by another agency we were unhappy with. The agency helped us get back on track, fix the issues from the previous developer and have the app approved on the Apple Store

Owner

We value AB4 Systems professionalism and their methodical approach to software development. We are first timers in this industry and their advice has been extremely valuable. Their expertise covers not only the technical and product side, but they are also very knowledgeable with the business, marketing, sales and funding side. We view them as our trusted technology partners.

Managing Director

AB4 Systems was our technology partner and they helped us with product strategy, technology decisions, design and development. They delivered everything what was agreed on in time and I highly value our relationship.

Create a mobile app  for our business idea to setup a platform for users to exchange cash.

Always, but we'll save that for the 2.0 version of the website.

AB4 understood exactly our needs and delivered right on time. It was a no hustle, stress free process in which their solution was the right one.

Owlight is a cool product that needed a really cool website in a short time.

Strategic Partner

Even though we had tough time constraints, the AB4 Systems managed to deliver an amazing app for both platforms. Our users can now buy tickets and see festival information from their own pockets. I highly recommend working with AB4, they are very professional

create an app for a film festival in order to bring more audience to the event

festivla director

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 &amp; beyond to find a creative solution. It’s the little things that make this group stand out from many others I’ve worked with in the past.

Advisor

AB4 Systems developed an animated sticker tool. In addition to building an Android version, the team created an iOS keyboard from scratch that suggests stickers based on the words typed by the user.

Compared to the previous iteration, the product that AB4 Systems created has received much better feedback from external users. Leveraging a collaborative and transparent approach, the team maintained a seamless workflow and provided recommendations as needed.

Product Manager

Magic happens when our creativity blends with the knowledge and experience of AB4 Systems team. We are very excited to see the brand new Animest app come to life.

Creative Director

Good communication. Easy to understand what they recommended

To create a simple and accessible mobile app to display the heritage of our village.

Coordinator voluntary community group

AB4 Systems proved to be a trustworthy partner throughout our collaboration, bringing our initial proposal to life with many enriched ideas and various alternatives to suit a very complex implementation plan. The software delivered worked flawlessly, had an easy to use interface and proved its reliability during time. I have no doubt we will work together in the coming periods.

Financial Accounting and Advisory Manager

I have worked with several offshore vendors over the years to supplement our internal software development team capacity, and AB4 Systems stands out for their technical knowledge and customer service skills.For anyone looking for a reliable technical partner, I strongly recommend AB4 systems.

BI Manager

We worked with AB4 Systems for a mobile app that connects your phone to your car computer and gathers specific information in order to predict recurrent behaviour of each driver. 

Their skills and proactivity made the project run very smooth.
A very successful project within the predicted budget.

Managing Partner

AB4 Systems proved to be a reliable partner throughout our collaboration, improving our initial ideas with their own vision. The software delivered worked flawlessly, had an easy to use interface and proved its reliability during time. For sure, we will work together in the coming periods.

Manager

We are amazed by the level of involvement of AB4 Systems in the product development process. We developed a mobile app together with them and we got amazing advice from AB4 with regards to product strategy, product design, technology stack, development. We will continue working with them.

Managing director

Managing the collaboration with AB4 Systems is really easy. They are proactive, professional and deliver on their work in a timely manner. Throughout my career as a project manager I have worked with a lot of companies and I can say that AB4 Systems is one of the best!

Digital Project Manager

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.

General Manager

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.

Director

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.

Lead Medical Consultant

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.

lead researcher

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.

Child Protection Consultant

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.

Operational Manager

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.
