SOSV

SOSV is a global venture capital firm that operates a number of highly specialized startup accelerators. Founded by Sean O'Sullivan, the firm's origin story is rooted in a desire to provide deep support and capital to founders tackling complex, often scientific and engineering-intensive challenges. Their mission is to back founders who are building the future, focusing on areas with significant societal impact and market potential. SOSV's investment thesis is unique in its accelerator-first approach, where they provide initial seed funding, intensive mentorship, and resources through their various programs, followed by follow-on investments. They are sector-agnostic in their overarching VC fund but highly specialized within their accelerators.

Notable programs include HAX, which focuses on hard tech and industrial innovation; IndieBio, a leading accelerator for biotech and life sciences startups; dlab, dedicated to blockchain and decentralized technologies; and MOX, which targets mobile internet companies in emerging markets. Their geographic focus is global, with accelerators located in key innovation hubs such as San Francisco, New York, Shenzhen, and Taipei. SOSV boasts a vast portfolio with thousands of companies, many of which have gone on to achieve significant milestones and valuations. Portfolio highlights include companies like Opentrons (robotics for biology), NotCo (plant-based food technology), and Perfect Day (animal-free dairy). What makes SOSV stand out is its hands-on, deeply technical accelerator model, combined with a willingness to invest in high-risk, high-reward deep tech and scientific ventures that often require longer development cycles and substantial capital. Their integrated approach of accelerator support and venture capital funding provides a comprehensive ecosystem for founders from idea to scale.
