What Petrichor Healthcare Capital Management does

Petrichor Healthcare Capital Management is a New York-based private investment firm founded in 2018 by Tadd Wessel alongside partners Patrick Lally and Michael Beecham, all previously of OrbiMed Advisors and Fortress Investment Group. The firm operates a dual-platform investment strategy focused exclusively on the healthcare and life sciences sector: Petrichor Capital Partners provides growth capital through customized convertible debt and equity structures to late-stage and commercial-stage biopharmaceutical, medical technology, diagnostics, and tech-enabled healthcare services companies, with typical investment sizes of $10 million to $50 million (expandable through limited partner co-investments); while Scion Life Sciences, an affiliated venture capital fund launched in February 2024 with $310 million in capital, focuses on founding and building exceptional biotechnology companies from inception through commercial maturity, deploying up to $60 million per portfolio company.

The firm generates revenue through standard private equity and venture capital economics, primarily management fees on committed capital and carried interest on realized gains, while adding value through active board participation (more than 60 board seats historically) and strategic advisory. To date, Petrichor's team has executed over 130 investments representing more than $6 billion of invested capital, including structured investments in Cryoport, ClearPoint Neuro, Fennec Pharmaceuticals, Tourmaline Bio, Aurion Biotech, Palvella Therapeutics, and many others across therapeutic, diagnostic, and healthcare services subsectors. Notable recent exits include Tourmaline Bio's agreement to be acquired by Novartis AG (September 2025), Lantheus Holdings' acquisition of Evergreen Theragnostics (April 2025, $250 million upfront), and Alcon's majority acquisition of Aurion Biotech (March 2025).

Petrichor's go-to-market is relationship-driven and highly specialized: the firm sources deals through direct engagement with management teams and boards, co-investor networks (Deerfield, KKR, Flying L Partners, PTC Therapeutics), and its portfolio-company referral base, and distributes capital and strategic support directly rather than through traditional channels. Limited partner relationships are anchored by institutional capital, with Archean Capital Partners serving as the anchor investor for the inaugural $410 million Petrichor Opportunities Fund I (November 2020). The firm maintains a small team (11-50) of scientific, medical, financial, and operational leaders, supplemented in 2026 by senior operating partners Don Hardison (former Exact Sciences CEO) and Paul Sekhri (former eGenesis CEO).
