OpenWealthLab

Real money. Real data. No bullshit.

OpenWealthLab is a public, data-driven wealth-tech lab. This site documents real portfolio actions, dividends, build progress, and experiments.

The Idea

I'm heinzer. 42. From Hamburg. I've been doing AI, data, and investing for 15+ years.

This lab is built on a simple idea: treat my portfolio like a machine learning problem. Not opinions. Not narratives. Just data, probabilities, and systems.

All posts here are generated from my actual transactions, dividends, and notes — structured data turned into narratives.
