About

I'm Jorrit. I help businesses put AI to work — and I build it myself.

Jorrit Keijzer

I'm a software engineer from the Netherlands. I spent my career at early-stage startups, where there's no one to hand work off to: you design it, build it and keep it running yourself.

That's still how I work. When a business asks me about AI, it doesn't end with a slide deck. I find where it actually saves time or money, build the solution, and make sure your team can carry on with it.

I work with small businesses and teams that don't have an AI specialist in-house. They don't need a big consultancy — they need someone who understands both the business question and the technology, and who's honest when AI isn't the answer.

Got a process that eats hours, or an idea you're not sure is feasible? Tell me about it. You'll get a straight answer on whether it's worth building.

What you can expect

Three promises, on every project.

Honest advice

If AI isn't the right answer, I'll tell you — even if that means less work for me. A demo that falls over in practice helps no one.

Something real, early

I'd rather put something working in front of your users early than plan for months. Then we improve it based on what actually happens.

You stay in control

Clear choices, no lock-in, and code your team can maintain. When I'm done, your team understands what was built and can keep it running.

Tell me what you're trying to do with AI — or what you suspect you could. I'll tell you honestly whether it's worth building.
