We are a software
development company

Our core business is developing complex management systems, web platforms, custom SaaS solutions, browser extensions, mobile applications, high-load solutions through AI-Accelerated Development or as AI-Driven Products

Why clients stay with us for years

What starts as software development often turns into something much bigger. We help clients not only launch products, but improve conversion, remove bottlenecks, test new ideas, and grow revenue over time. For us, the real value is not in simply writing code, but in helping the product perform in the real market.

That is why many clients stay with us for 3, 5, 10, or more years. What starts as one project often grows into long-term cooperation across multiple products and business directions. Over time, we become a reliable extension of the client’s team, often acting as their own dedicated IT department. Most of our new clients are referred to us by existing and long-term clients.

AI-Accelerated Development

We use AI solutions such as Claude, ChatGPT, Gemini, JetBrains AI, NotebookLM, and others across all stages of software design, from PRD to developing and testing. This helps us accelerate delivery by an average of 40% while improving efficiency and reducing routine work without compromising quality.

AI-Driven Product Development

Combined with 20 years of company experience and expertise in more than 30 fields it allows us to create deep PRDs, effective prompts, verify results, testing, deploy and develop new versions. We do not just build AI features. We build AI-powered products that work in the real world.

Today abz.agency turns 21 🎉 Over the years, we’ve been through many crises: 2008, 2014, the pandemic, the full-scale invasion. And after every crisis came growth. Before every period of growth, there were hard decisions and risks. We build custom solutions based on web technologies, as well as for iOS, Android, Windows and macOS: management systems, high-load portals, SaaS projects and complex products tailored to specific business needs. Our mission and goal is to deliver projects on time and with the required quality. Every one or two days, our clients receive a completed functional block according to the PRD. That’s why clients stay with us for 5–10 years. Today AI is changing the market, and not only in IT. Once again, we have to make tough, sometimes unpopular decisions, rethink our approaches and search for our “blue ocean” all over again. More than a year ago, we brought AI into our development process. For clients working with us on the Dedicated Team model, we use the AI Software Factory approach: AI agents write code, do code reviews and run tests. The team oversees the process, steps in when needed and is responsible for security and stable operation. Thank you to our team and our clients for these 21 years. The best is yet to come.

How do we actually use AI in our projects? AI agents have taken over a large part of the routine work in our projects. We call this way of working the AI Software Factory. Clients notice it before the work starts. We can now build a working prototype of the product while we are still discussing the brief, so the client makes early decisions on screens they can click through instead of in a document. Within a Dedicated Team, agents take a task, write the code, run the checks and fix what fails. Models from different vendors review each change, and the agent that wrote the code never reviews its own work. When an agent cannot finish, it stops and says what a person needs to decide. Our developers set the tasks and own the architecture. Changes to payments and core code always get a full human review, and a person approves every merge. With the AI Software Factory the routine work goes faster, and the people who have run our clients projects for years still decide what gets built.

What
clients say

It has been an absolute pleasure to work with the ABZ team on various challenging web technology based development projects. They are true professionals of the highest order and always deliver, as promised, on time and to the highest quality standards. ABZ has an excellent team of incredibly skilled developers, talented designers and effective product delivery managers who are able to take highly complex requirements and turn them into flawless products. Their internal organization is setup in a highly efficient way and our communication with them has been both frictionless and pleasant. It is rare to find a partner that is so trustworthy and reliable as ABZ has been on our projects. I can highly recommend ABZ to anyone who is looking for an excellent development partner and we hope to do many more projects with them in the future.

Working with ABZ agency is a real game changer for our project!

We went from complete chaos to order, we simply love their rules and processes, and we can see that they have spent years perfecting them to make collaboration the best it can be.

Often in projects, miscommunication is what causes a LOT of trouble (trust me, we wasted tens of thousands of euros in rework due to miscommunication, and that’s excluding the missed opportunity costs), and ABZ solves this issues with a few unorthodox approaches :

- No calls : this rule is amazing ! Scary, but amazing! We were anxious that it would be an issue but we haven’t had any problems, on the contrary, all the miscommunication that was happening with previous IT company due to lack of writing things down, is now gone! Everything is written, clarified, and findable again for later reference.

- No coding before requirements are clear : they ask a lot of questions, and when I see how clean their delivrables are, I am thankful for all their questions.

- Frontend starts in Figma : again, a great rule to avoid rework, design needs to be done 100% (for every single change) before frontend devs integrate it, there are no approximations, and the result is pixel perfect integrations!

We look forward to continuing to trust ABZ with the development of our project, and we’re very grateful for the attention and quality of service that they provide us with.

We’ve worked with ABZ on a number of projects - mainly Google Chrome Extensions. The work they’ve done has been exceptional. The projects we have worked on together have been complex and have involved integration with other systems involving APIs. The innovation, communication and quality for work has been excellent overall. Put simply, the guys at ABZ are some of the best developers. I’ve worked with in a 30 year IT career. I have super high standards but ABZ exceed them every single time.
