The SOSV Climate Tech 100

 In Blog

The achievements of science in the past 20 years have given mankind the unprecedented ability to re-engineer the material world. As a result, we have the nearly miraculous ability to turn the tide on climate change. From my vantage point at SOSV, I am convinced that we are witnessing a remarkable coming together of the advances in technology, the societal commitment, and the financial wherewithal that we need to solve the greatest threat facing humanity.”

— Sean O’Sullivan, SOSV Managing Partner

SOSV has always been keen on technology and startups that promise better human and planetary health. In recent years, climate tech has been an especially big priority at our IndieBio (biotech) and HAX (hardware) accelerator programs. The SOSV Climate Tech 100 marks the first time we’ve analyzed our 1,000 company portfolio to present our top climate tech investments.

We are pleased to report that as of April 2021 the SOSV Climate Tech 100 have raised $1.85 billion from investors and have a market cap of $5.65 billion. The average company is four years old. SOSV has invested $89 million in these companies and was in most cases the first investor, though we continued investing through early rounds.

Not all the companies on the list contribute in the same way to climate tech, so we grouped them in three broad tiers. The core (71) are companies that aim to disrupt incumbent, carbon-intensive technologies. The adjacent (25) are companies that have an indirect impact on climate change, for example by re-using waste or power consumption. And marketplaces (4) typically provide consumers with more cost and carbon efficient solutions.

Here are a few data points to help navigate The SOSV Tech Climate 100. We divided the companies into five industry categories: Food (50), Manufacturing (28), Transport (9), Energy (7) and Building Systems (6). There are 14 countries represented, with the US (65), Canada (9), Singapore (6), and the UK (6) topping the list. 40 percent of the companies have at least one female founder. And a final note: SOSV has invested in more than 40 additional climate tech companies that we also love but didn’t make the cut this year!
