SOSV closes $277M fourth fund, exceeding target by over 10%

In June 2018 SOSV first disclosed plans to raise a $250 million fourth flagship fund. By mid‑2023 the firm had secured commitments from over 120 limited partners—including Tiedemann Advisors, Davy Group, HP Tech Ventures, ZX Ventures (AB InBev), Honda Motors and nine unnamed venture capitalists—allowing it to raise $277 million, more than 10 % above the original target.

SOSV says it will continue to invest roughly $100k‑$250k per startup across its vertical‑specific accelerators (IndieBio, HAX, Food‑X, Mobile‑Only Accelerator) and keep follow‑on reserves of $200k‑$2 million per company, while allocating $10 million each year to build and maintain wet labs, electronics labs and mechanical facilities for its portfolio.

$277 million fund enabling SOSV to back ~150 deep‑tech startups yearly, maintain $200k‑$2M follow‑on reserves, and invest $10 million annually in lab infrastructure

Strong LP demand from corporate and venture investors reflected confidence in SOSV’s deep‑tech focus.

The firm’s track record of accelerating early‑stage deep‑tech ventures made the fund attractive despite a crowded VC landscape.

Oversubscribing the fund provides a buffer for follow‑on investments and infrastructure spending.

Exceeding fundraising targets signals strong confidence in a specialized accelerator model and provides the dry powder needed to sustain high‑conviction, long‑horizon deep‑tech investments.

Since the close, SOSV has maintained its pace of funding about 150 companies per year, continued to operate accelerator programs in San Francisco, New York, Cork, London, Shenzhen, Shanghai, Xi’An, Taipei and Tokyo, and has kept investing $10 million annually in lab infrastructure for its portfolio companies.
