Atomic AI is a South San Francisco biotechnology company fusing machine learning with structural biology to unlock RNA drug discovery. Its platform pairs in-house wet-lab chemical-mapping data with deep learning models - including ATOM-1, a foundation model for RNA structure, and PARSE, its RNA structure exploration platform - to find structured, ligandable RNA motifs and design selective small molecules and RNA-based medicines for targets long considered undruggable.

Yoneda Labs is building the foundation model for chemical manufacturing - think of it as the AI brain that tells chemists exactly which conditions to use to make a reaction work, before they spend months running dead-end experiments. Founded by three Cambridge graduates and backed by Khosla Ventures and Y Combinator, the company's software suite (Predict, Optimize, Analyze) compresses reaction optimization timelines from months to days. Their first named partnership with Symeres pushed cross-coupling reaction yields from ~30% to over 90%. The goal: become the universal AI layer for the $5 trillion chemical industry.
