What TCG Crossover does

TCG Crossover ("TCGX") is a science-driven healthcare investment firm founded in 2021 by Dr. Chen Yu after sixteen years as a Managing Partner at Vivo Capital. The firm manages a series of closed-end funds that deploy patient capital into biotech companies developing transformative medicines at any stage of their lifecycle. TCGX has raised three successive oversubscribed funds: the inaugural Fund I at $824M (April 2021), Fund II at $1B (January 2024), and Fund III at $1.3B (October 2025), bringing cumulative commitments to approximately $3.1 billion. Capital is deployed globally across North America, Europe, and China, with offices in Palo Alto (headquarters), New York, and San Francisco, and approximately 20-25 total employees.

The firm's core differentiator is its Science Network of eight Science Partners that includes Nobel-caliber scientists such as former HHMI President Robert Tjian, former Merck R&D head Roger Perlmutter (now CEO of Eikon Therapeutics), Lasker Award winner Charles Sawyers, and Pfizer board member Helen Hobbs. The investment team is led by three Managing Partners (Chen Yu, Cariad Chester, Giuliano Marostica) with operating, scientific, and investment banking backgrounds, supported by a venture formation-focused Venture Partner (Dandan Dong, ex-ArriVent Biopharma CBO) and Associates with credentials from Stanford, MIT, Harvard, NEA, Goldman Sachs, Evercore, and Foresite Capital. The Science Network functions as the firm's primary deal-sourcing channel and diligence engine, distinguishing TCGX from generalist crossover funds.

TCGX generates revenue through traditional fund management economics, charging management fees and earning performance carry on its closed-end fund vehicles. The firm does not sell products or services in the conventional sense; rather, it invests institutional LP capital into private and public biotech companies. Its portfolio of 25+ private companies spans modalities including ADCs, gene therapy, oral peptides, radiopharmaceuticals, cell therapy, and vaccines, with notable outcomes including pharma acquisitions by Roche (Carmot), AstraZeneca (Icosavax, Gracell), Eli Lilly (Versanis), GSK (RAPT Therapeutics), Sanofi (Vicebio), Novartis (Tourmaline Bio), and UCB (Candid Therapeutics), plus IPOs of CG Oncology and Structure Therapeutics.
