Atomic AI Raises $35 Million in Series A  

by Kay Aloha Villamor in January 26th, 2023

Atomic AI, a San Francisco, CA-based biotechnology company fusing cutting-edge machine learning with state-of-the-art structural biology to unlock RNA drug discovery, launched with a $35 million Series A funding, bringing its total raised to $42 million.

The round was led by Playground Global, with participation from 8VC, Factory HQ, Greylock, NotBoring, AME Cloud Ventures, and renowned angel investors including GitHub ex-CEO Nat Friedman, Doug Mohr, Curai CEO Neal Khosla, and UC Berkeley professor and Arc Institute Co-founder Patrick Hsu.

“To create effective and safer small molecules against undruggable diseases, there is a significant need to develop tools that can accurately predict 3D RNA structures,” said Raphael Townshend, Ph.D., Founder, and CEO of Atomic AI. “Atomic AI is oriented at the cutting edge of AI, RNA, and structural biology. We are creating an entirely new field of drug discovery.”

Atomic AI's proprietary AI-driven 3D RNA structure engine, featured prominently in Science, generates RNA structural datasets by integrating machine learning foundation models with large-scale in-house experimental wet-lab biology to enable the world of RNA drug discovery.

Atomic AI's technology, in particular, can discover structured, ligandable RNA motifs at unprecedented speed and accuracy, overcoming a critical barrier in current approaches to small molecule drug discovery against RNA.

Aside from RNA-targeted molecules, the integrated platform will allow the development of RNA-based medicines and RNA tools.
