b12 labs

AI-powered chemical synthesis platform for pharmaceutical and biotech research, specializing in complex molecules, multi-step targets, and novel scaffolds.

About b12 labs

b12 makes high-value molecules that are otherwise hard to make. We help pharma companies plan and make new drugs, accelerating early-stage drug discovery from years to months.

Andres built the first AI agent that can autonomously think and make molecules in a robotic lab, published in Nature Machine Intelligence (1000+ citations), and won the best paper award at the NeurIPS AI for Science conference. Zlatko is a 3x National Chemistry Olympiad champion, competed at IChO level, and medicinal chemist who has worked at Roche and leading lab robotics companies.

Combined, we have an extensive network of hundreds of chemists, automation scientists, and AI 4 Science researchers.

We run paid pilots with big pharma companies, demonstrating that our platform planned a set of experiments that achieved full conversion in a single attempt, eliminating the iteration cycle.
