AboutReqursor Technologies

Built on recursion

Reqursor Technologies is a software company based in Rotterdam, The Netherlands. We build autonomous software: products that take on real engineering work, within limits you can verify.

The name

Why Reqursor?

Reqursor comes from recursion, the favorite computer science concept of our founders, Maurice and Yassine.

A recursive function is defined in terms of itself. It applies one fixed rule, then calls itself again on the result. The rule never changes, but the input does, so every call produces something new, and step by step a simple rule builds something far larger than a single step could.

That was the idea behind Reqursor from the start: a system that builds new systems, using the same system.

It still describes how we work. Reqursor Development began as the tool we built to help develop our own software. Today it is a product in its own right.

recursion.ts
// One rule, applied to its own output.
function recurse(system: System): System {
  if (system.isComplete()) return system;
  return recurse(system.buildNext());
}

recurse(v1) → recurse(v2) → recurse(v3) → … → done

What we do

Agentic AI, held to engineering standards

AI agents can plan and carry out multi-step work instead of answering a single prompt. That makes them useful for real engineering, and it makes verification essential.

So we hold AI agents to strict engineering checks: automatic validation, your own tests, independent review and a clear audit trail. The AI does the work; the checks decide whether it ships.

How we make decisions

Four principles shape every product we build.

  • Predictable where it counts

    AI can be creative. Putting its work into production should be predictable, so we turn AI output into steps that can be checked, repeated and reversed.

  • Evidence over claims

    We don't ask you to take our software's word for it. Every change comes with the evidence behind it.

  • People set the direction

    Our software carries out the work. Your team decides what gets built and what gets approved.

  • Clear about status

    We describe what our products do today and say plainly what is still in development.
