Vertical AI
Wet lab infrastructure that turns AI experiments into training data.
Real biology requires a wet lab, and building one takes years and a team most AI companies don't have. Petrichor runs their experiments at scale and sends back the dense, clean data their models need to learn from. The company was founded by Wilhelm Hedenskog; Jesper Johansson; Elias Reinfeldt.
It is part of YC Fall 2026. It is based in San Francisco, CA, USA.
