Joachim Holwech

Hi, I'm Joachim Holwech!

Founder and indie hacker with background as a software developer, data scientist and product manager. Experienced in commodity trading, energy markets and cost estimation for renewable energy projects.

As the sole developer, I co-founded and built the POWELY hydrogen cost estimation tool and electrolyzer marketplace from scratch to a product that helped us raise pre-seed funding in under 9 months.

On April 11th, 2023, I decided to all-in as a solo founder and indie hacker. I'm following the "build in public" philosophy and sharing my progress on the way. I strive to be as transparent as possible, sharing my metrics, goals and failures.

Follow me on my journey to build a profitable business from scratch on my blog.
