Two Graphics Cards in the Basement

August 19, 2026

There is a machine in my basement with two graphics cards. AI models work on it day and night. Nobody can rate-limit them, nobody can raise the price, nobody reads along.

One of the two graphics cards: an NVIDIA GeForce RTX 5090 Founders Edition, fresh out of the box.

It started as an after-hours project. Some hardware, a few open models, a lot of trial and error. It is now one of the reasons I left my job.

From 1 October 2026 I am self-employed

After many years leading software and product development, most recently as Head of Development, I will be advising companies on private and agentic AI: which hardware, which models, which architecture. So that AI actually becomes productive and the data stays inside the company.

Why now?

Because a side project turned into a conviction: the road to AI does not have to run through a US cloud provider.

A lot of what is billed per user per month today runs locally. Fast enough, cheap enough, and auditable. Not everything, for some tasks the large frontier models are still the right tool. But the share of work that runs well on your own hardware has grown considerably over the past year, and for many mid-sized companies the maths now works out.

Closer to the metal

I will be working far more hands-on again. What makes that possible is the technology itself: AI agents take over the legwork in the background. That frees up time for the part that matters most now — working with people.

I am starting solo, with a clear plan to grow together with a partner.

From October I have capacity

For projects, sparring, and partnerships. And if someone came to mind while you were reading this, someone facing exactly these questions: I would be glad for an introduction.
