Christoph Hartmann

I am the founder of the AI productivity startup DoneThat. I worked for a while in AI, including a PhD, a stint at BCG, and as a CTO for a scale-up. On the side, I am writing about elements of a good life at Euzoia. I have pledged to donate 10% of my income and 50% of my exit proceed to charities.
