About

I co-founded a software agency and helped grow it to 40+ people. Then I left.

Afterwards I built a SaaS on my own. It didn't work: 0 paying customers for 10 weeks. I'll write about why.

Now I'm running a 90-day challenge. I publish what I do, with the real numbers. Failures included.

What you'll find here

• Decisions and the numbers behind them
• Mistakes, and what I learned from them
• Tools I use, and where they fall short

What I'm doing

For the first 60 days I'm not building a product. I log every time a tool doesn't do what I want. On day 60 I read the list. Whatever hurts most becomes the next product.

I'm based in Germany. Find me on X, or subscribe to the newsletter below.
