Atria Ventures

Atria Ventures is a San Francisco-based venture capital firm founded in 2023 by General Partner Chris Leiter. The firm invests at the intersection of life sciences and artificial intelligence, partnering with founders working at the edges of biology and human health to reimagine the trillion-dollar life sciences industry from molecule to patient. Atria leads rounds at pre-seed and seed stages, with a sweet spot of $800,000 and a range of $250,000 to $2 million. Through its closed Fund I, Atria has made 15 investments across healthcare AI, biotech, and clinical development. Notable portfolio companies include Sleuth Insights in healthcare analytics, Peer AI in healthcare artificial intelligence, and Trially in clinical trials technology. The most recent investment was in Peer AI's Series A in October 2025, reflecting the firm's commitment to following its strongest portfolio companies into later rounds. Atria differentiates itself through singular focus on the convergence of computational approaches and life sciences — a sector where AI is fundamentally transforming drug discovery, diagnostics, clinical trials, and patient care delivery. Rather than investing broadly across healthcare, the firm concentrates on companies where deep learning, biological data, and clinical insight create compounding advantages. Chris Leiter's background informs a hands-on, thesis-driven approach that prioritizes founders working on problems with both scientific novelty and clear paths to clinical or commercial adoption.
