SOSV

SOSV Research Document Investment Thesis SOSV is "The First Check in Deep Tech®" - a global, multi-stage venture capital firm uniquely positioned at the intersection of venture capital and startup development programs. Founded in 1995 by serial founder Sean O'Sullivan, SOSV's core thesis is that the most transformative companies solving human and planetary health will emerge from deep tech founders who combine rigorous science and engineering with entrepreneurial vision. SOSV doesn't just provide capital; it provides an extraordinary ecosystem. The firm operates HAX (hardware and robotics) and IndieBio (biotech and life sciences) - industry-leading startup development programs with 85,000 square feet of in-house labs, manufacturing facilities, and specialized equipment. SOSV believes that great founders come from all geographies and backgrounds, and systematically seeks to democratize deep tech innovation.
