Breakout Ventures

Breakout Ventures is a San Francisco-based early-stage venture firm focused on science-driven companies at the intersection of biology, chemistry, and engineering. The firm’s thesis is explicitly deep tech and life sciences — synthetic biology, agri-food, climate, and biomedical platforms — and they are known for backing technically credentialed founders solving large industrial or biological problems. Healthcare exposure is a material slice of their portfolio, particularly in therapeutics platforms, novel diagnostics, and biology-enabled tools, but not in pure software-driven digital health. For healthcare AI founders, Breakout is the right partner if your company sits at the convergence of AI and wet-lab biology — protein design, synthetic biology automation, AI-driven drug discovery, novel diagnostics, biomanufacturing — where the technical risk is real and the commercial pathway runs through pharma, biotech, or industrial partnerships. Stage focus is seed and Series A, with check sizes plausibly $1M to $5M and a willingness to lead. Founders who should approach: PhD-credentialed founding teams with proprietary IP, a clear technical milestone roadmap, and a thoughtful capital plan to clinical or commercial validation. Founders who should not approach: pure software healthcare apps, clinical workflow tools, and consumer health products — these are far outside the thesis. Entry path is warm introduction through their portfolio CEOs, university tech-transfer offices (Stanford, UCSF, MIT, Berkeley), or scientific advisors in their network. Their LinkedIn and Crunchbase pages list partners and portfolio that map the relevant referrer pool. Be ready to defend the science.
