We Are SOSV

With more than $1.5 billion in assets under management and more than 300 investments per year, including 100+ pre-seed rounds in new startups, SOSV is one of the most active venture investors in the world. Our industry-leading startup development programs include HAX (hard tech), IndieBio (human and planetary health), Orbit Startups (growth in emerging and frontier markets) and dlab (web3, decentralization, blockchain).

Deep tech for humanity

SOSV’s core mission is to fund visionary, deep tech founders who aim to deliver a radically beneficial impact on human and planetary health. As of April 2022, our top 100 climate tech companies have an aggregate valuation of more than $11 billion and have raised $3.85  billion, while our top 100 health startups are valued at $5.7 billion with $1 billion raised. SOSV is consistently ranked by PitchBook as a top investor in both categories.

High touch, high value

SOSV is building companies, not just taking founders’ equity for advice and introductions. Our startup development programs offer in-person and remote options with a 1:2 staff-to-founder ratio, including engineering, science and startup experts working in advanced lab and fabrication facilities. Our approach helps founders hit critical inflection points sooner, which speeds up fund-raising and reduces dilution. SOSV helps founders go further, faster.

First of Many Checks

First of many checks

At SOSV, a pre-seed investment is the beginning, not the end. We start investing with up to $500,000 when a startup joins one of our programs. We continue funding successful companies through series seed, series A and beyond, thanks to the SOSV Select Fund. Our general partners tap our network of thousands of investors to help founders find lead investors and syndicate partners. In 2021, SOSV made follow-on investments  in 196 program alumni companies. Last year, SOSV companies raised $2.2 billion.

Diverse by design

SOSV recognized before Silicon Valley that great founders come from all geographies, genders and races. Our 2600 founders represent 84 nationalities and operate in 56 countries. More than 70% of our founders are from outside the US, and 30% are from low- to middle-income countries, as defined by the World Bank. SOSV has a strong track record of investing in women entrepreneurs. SOSV has invested in 500 women founders, and 1 in 3 of our companies have at least one female founder. Approximately $1 in every $3 that SOSV invests through its core funds goes to a company led by a female founder.

SOSV For Life
IndieBio SF demo day

SOSV for life 

A typical startup “accelerator” has little to offer once demo day is done, which is one reason SOSV no longer uses the term. At SOSV, we not only continue investing long after startups have completed our programs, we offer an open platform to support our program alums.

We continue to make investor introductions and provide ongoing access to experts on the SOSV teams. SOSV also maintains a vibrant, Slack-based peer-to-peer founder community and programs private founder-focused events covering topics from legal to marketing. We also provide our startups visibility through public franchises such as the SOSV Climate Tech 100, the SOSV Human Health 100, and the SOSV Climate Tech Summit. SOSV is for life.
