Boom Capital

Boom Capital is a San Francisco-based pre-seed and early-stage venture capital firm founded in 2017 by Celestine Schnugg (formerly at Innovation Endeavors and Apple), specializing in deeply technical, often under-networked founders building frontier technologies in areas like biotechnology, genomics, synthetic biology, machine intelligence/AI, aerospace, and advanced chemistries. The firm focuses on being the "first believer" with small initial checks (typically $50K-$300K), providing hands-on support and community-building through events like Boomworld gatherings of scientist collectives, while recently closing a $14.5 million Fund II targeted at underrepresented founders. With around 40 investments as of 2025, the portfolio features high-impact deep tech successes such as first checks into Mammoth Biosciences (CRISPR unicorn), Fauna Bio, A-Alpha Bio, Nabla Bio, and early bets on Astra (public), Swarm Technologies (acquired by SpaceX), Planet (public), alongside recent plays like Samaya AI, Olio Labs, and Bioptimus, demonstrating a strong track record in transformative science-driven companies.
