b12 Labs

Startup

b-12 (YC S25) is building Reasoning Agents for Chemistry. Founded by EPFL experts Andres (ChemCrow author) and Zlatko (ex-Chemspeed), we are transforming how labs autonopmous labs are working. Our agents directly translate literature procedures into executable code for automation platforms like Chemspeed and Unchained Labs. By applying deep chemical reasoning to retrosynthsis and HTE plate creation, we help labs achieve full conversion on challenging reactions on the first shot. We are proud to be already working with top pharma, biotech and CROs around the globe.
