The top 100 venture investors in biotech

An annual ranking of the 100 most active venture investors in private biotech rounds, produced by Endpoints News with data from DealForma. Investors are ranked by the capital in new funding rounds they joined in the prior year, and the list is a common reference for biotech founders mapping the investor landscape.

How the ranking works

DealForma (analyst Chris Dokomajilar) compiles and fact-checks the rankings from its biopharma deal database. The 2025 event page describes the list as identifying 'the leading 100 venture capital firms investing in biotech based on capital deployed in new funding rounds'; in practice the headline figure is the total size of rounds a firm participated in (OrbiMed's 2025 figure was '$5.9 billion'), because individual check sizes are rarely disclosed. The 2020 article noted it is 'impossible to say exactly how much they invested in total'.

The article also reports deal counts per investor. Weights and tie rules are not published in the free portion; the full list is behind Endpoints' registration or premium wall.

Ranked positions: Each item has a position (1, 2, 3), with ties allowed. Firms cannot apply or pay; DealForma compiles and fact-checks rankings from its deal database. The full article sits behind an Endpoints sign-up or premium wall, and ranked firms' partners appear as panelists on the companion webinar.

History

Endpoints and DealForma have published the list each winter since at least January 2019 (2018 data), with editions found for 2019, 2020, 2022, 2023, 2024, 2025 and 2026; a 2021 edition likely exists but was not located. RA Capital Management was the most ubiquitous investor in several recent editions; in the February 2026 edition OrbiMed moved to first place after more than doubling its deal activity to $5.9 billion, with RA Capital second. Since about 2022 each edition has been paired with a live webinar featuring partners from ranked firms.

How it is received

The list is widely referenced in biotech media and by DealForma itself. No attributable published criticism was found. A structural limitation, acknowledged in the 2020 article, is that the ranking reflects round sizes a firm joined rather than dollars it invested.

Strengths

  • Specialist biotech deal data compiled and fact-checked by DealForma.
  • Long run of annual editions since at least 2019.
  • Covers 100 investors, wider than most sector top 10s.
  • Includes crossover and corporate investors active in private rounds.

Weaknesses

  • Full list is behind an Endpoints sign-up or premium wall.
  • Ranks by total round size joined, not actual dollars invested, which favors participants in megarounds.
  • Methodology details are not published in the free portion.
  • Ranked firms' partners headline the companion webinar, a commercial tie.
