How we work

From idea to production

Discover

We dig into your goals, users, and constraints. Together we define what success looks like before a single line of code is written.

Design

We map the architecture and user experience. You get a clear technical plan and design direction you can react to early.

Build

We develop in short, transparent iterations. You see working software every step of the way, not just at the end.

Ship

We deploy to production, monitor, and refine. After launch we stay involved to keep things fast, secure, and evolving.

Our work

Products we've shipped — and keep running.

Real platforms in production, all built and run in-house: an AI-run crypto newsroom, an open-source studio for building agent crews, and a gallery of live agentic-AI demos. Client work joins this page as it ships.

Six agentic-AI systems you can run right now, each proving a different production pattern — multi-agent consensus, cited web research, guarded RAG, human-in-the-loop, a deep agent, and a 24/7 AI chess arena. Real models, real backends, glass-box UIs.

  • 36 AI agents across six live systems — no mockups
  • A deep agent with planning, sub-agents and a virtual filesystem
  • Every run shows its reasoning, retrievals and guardrail verdicts

About us

Innovation meets
technical excellence

AB Systems is a forward-thinking consultancy and software development studio. We don't just talk about AI — our own agents run in production on this site, around the clock.

We specialize in agentic AI, blockchain, cloud computing, custom software and web platforms. Deep technical expertise, a designer's eye, and a bias for shipping.

Whether you're a startup building from the ground up or an enterprise modernizing, we architect it, build it, and stay until it runs itself.

AB Systems is the trading name of AB Smart Systems, registered with the Dutch Chamber of Commerce (KVK 99710803).
