DateStageInvestorsRaisedDeal Summary
Oct 2025Series ASamsara BioCapital (lead); Decheng Capital; Red Tree Venture Capital$70MExcellergy, a Palo Alto-based biotechnology company, emerged from stealth on October 13, 2025, with a $70 million Series A financing round led by Samsara BioCapital, with co-investments from Red Tree Venture Capital and Decheng Capital. The company was founded in 2021 with seed funding from Red Tree Venture Capital and is built on scientific advances in structural binding of IgE to its receptor developed at Stanford University and the University of Bern. Excellergy is developing a first-in-class portfolio of trifunctional Effector Cell Response Inhibitors (ECRIs) designed to deliver complete allergic control by targeting multiple pathways—removing receptor-bound IgE, neutralizing free IgE, and down-regulating FcεRI—with a mechanism distinct from traditional anti-IgE therapies. The company is led by President and CEO Todd Zavodnick, formerly of Dermavant Sciences at Roivant, alongside co-founder and Chief Scientific Officer Geoffrey Harris, Ph.D. (who founded liver-focused Ocelot Bio), and Chief Medical Officer Philip Brown, M.D. (previously at Dermavant). The $70 million Series A funding is intended to support advancement of the company's preclinical portfolio into first-in-human clinical studies, with a lead asset expected to enter human testing in early 2026. Initial development targets include food allergy and chronic spontaneous urticaria. At the time of the Series A announcement, the company was pre-clinical and had not generated commercial revenue.
