Shengfang Jin is a co-founder and the President and CEO of Ensem Therapeutics, a Waltham, Massachusetts biotech developing small-molecule cancer drugs by targeting protein pockets that only exist while the protein is in motion. Under Jin, Ensem built its Kinetic Ensemble platform, took its first CDK2 inhibitor into the clinic, and its ETX-636 breast cancer program earned FDA Fast Track designation. She trained at Tufts and Harvard, spent years at Agios helping deliver first-in-class cancer metabolism drugs, and then ran discovery biology at Editas before starting Ensem.
MOMA Therapeutics is a Cambridge, Massachusetts biotech building precision small-molecule medicines against 'molecular machines' - the highly dynamic, shape-shifting enzymes (ATPases, GTPases and related proteins) that power cellular processes and underlie cancer and other diseases. Spun out of Third Rock Ventures in 2020 by four academic leaders in protein biophysics and structural biology, MOMA's proprietary KNOMATIC platform fuses deep structural insight, advanced hit-finding (fragment and DNA-encoded library screening) and machine-learning-driven lead optimization to drug targets long considered intractable. The company has raised about $236M, advanced its first oncology program into the clinic, and partnered with Roche and Bayer.
Fathom Therapeutics (formerly Atommap) is a New York and Boston based biotech building Microcosmos, a drug-design engine that fuses quantum chemistry and AI to simulate how proteins actually move inside living cells. By modeling motion instead of static snapshots - reportedly up to 10,000x faster than conventional simulation - the company hunts for the fleeting binding pockets that make 'undruggable' targets druggable, then designs small molecules, degraders, and molecular glues against them. In April 2026 it raised a $47M oversubscribed Series A led by Sutter Hill Ventures.
Huafeng Xu is the founder and CEO of Fathom Therapeutics (formerly AtomMap), a New York drug-design company that simulates protein motion at atomic resolution to design small molecules that work inside living cells. A computational chemist with 25+ years and 10,000+ citations, Xu spent 12 years at D. E. Shaw Research building the free-energy and molecular-dynamics methods now standard across pharma, then served as CTO of Silicon Therapeutics and Roivant Discovery before launching his own company. In April 2026 Fathom closed an oversubscribed $47M Series A led by Sutter Hill Ventures to scale its Microcosmos engine.
