We Are SOSV
SOSV’s mission to support human and planetary health spans the globe with nearly 1000 startups operating in 60 countries and SOSV programs based from New York City and Newark, to San Francisco, Shenzhen, Shanghai, Taipei, and Tokyo. Everywhere, we’re helping founders go further, faster.
SOSV is a global, multi-stage venture capital firm that operates early stage startup development programs, notably HAX, IndieBio, and Orbit Startups. SOSV’s core mission is to fund visionary, deep tech founders who will have a profound impact in the areas of human and planetary health. As of April 2023, SOSV’s top 100 climate tech companies had a valuation of $11.69 billion with $3.77 billion raised, and our top 100 health startups had a valuation of $6.47 billion with $1.42 billion raised. SOSV is consistently ranked by Pitchbook as a top investor in both categories.
As of January 2023, SOSV had more than $1.5 billion in assets under management, and according to Pitchbook is the top ranked investor in climate and food tech.
In 2021, the firm launched the SOSV Climate Tech Summit, an annual, virtual event that features top climate founders and investors. The second summit, in Oct. 2022, attracted more than 3000 attendees, and the 2023 summit is slated for Sept. 26-27.
Among the top companies in SOSV’s portfolio are NotCo, Perfect Day, Upside Foods, The EVERY company, Formlabs, Opentrons, Smartex, R-Zero, Voltstorage, Prolific Machines, Geltor, Mycoworks, Green Li-on, and Videoverse.
Each year, SOSV selects 100 or more highly promising, seed and pre-seed startups to join SOSV’s programs based in San Francisco, Shenzhen, New York City, Newark (NJ), Tokyo and Shanghai. SOSV makes an initial investment of up to $500,000 and the founders spend four-to-six months working side-by-side with SOSV staff and mentors who are deeply expert in science and engineering, design and product development, supply chain and product-market fit, growth, and raising capital.
The goal in each program is to help each startup prove out their value by getting increased scientific and marketplace traction, and increased clarity about their product’s value and positioning to solve urgent problems. At that point, fundraising progress becomes relatively easy, and seed and Series A rounds attract top venture investors.
SOSV joins those later rounds and SOSV general partners continue working closely with the program alums for years post-program. In 2022, SOSV portfolio companies raised $2.0 billion in follow-on rounds, and SOSV participated in 161 of those rounds as well as more than 100 pre-seed rounds for startups that joined SOSV programs. According to Pitchbook, SOSV was the most active seed and angel investor in the world in 2020 and 2021, and third most active in 2022.
SOSV’s startup development programs include hard tech-oriented HAX and human-and-planetary-health driven IndieBio. Both offer deep technical and company-building expertise as well as well-equipped lab and fabrication facilities. At Orbit Startups (successor to Chinaccelerator and MOX announced in July 2022), growth experts help entrepreneurs expand globally from faster emerging and frontier markets. SOSV launched the dlab startup development program in 2019 to focus on Web3 technologies, and on January 1, 2023 SOSV spun dlab out as a standalone fund.
SOSV Managing General Partner Sean O’Sullivan founded SOSV in 1995, following the IPO of MapInfo, a startup he co-founded that pioneered computer-based street mapping. O’Sullivan is deeply committed to human and planetary health through entrepreneurship and technology, and he is actively involved with all the programs.
O’Sullivan has donated tens of millions in profits from his investments to charitable causes, including the Khan Academy and CoderDojo, as well as many other educational and humanitarian efforts. As a firm, SOSV commits 10% of SOSV profits (“SOSV carry”) to philanthropy. He resides in Princeton, NJ.
Over the last 25 years, SOSV grew from just O’Sullivan to a firm with over 130 staff, including 11 General Partners.
