Why is SOSV producing this event?

The Princeton, NJ-based venture capital firm SOSV has been producing the Climate Tech Summit since 2021. In 2022, the event brought together nearly 7,000 attendees from around the world to listen to the world’s top founders and investors in climate tech. The third SOSV Climate Tech Summit will take place on Sept. 26-27, 2023.

SOSV is a leader in early stage climate tech investing, thanks to its IndieBio (life sciences) and HAX  (hard tech) startup development programs.

SOSV publishes yearly the SOSV Climate Tech 100, listing its most promising investments in the category. Pitchbook reported that SOSV was the #1 most active climate tech investor for the 2018-2020 period.

SOSV has more than 500 co-investors in its climate tech portfolio, and in June this year SOSV published an analysis on TechCrunch of those investors as a guide to help founders better understand the funding landscape. SOSV is deeply committed the the mission of “human and planetary health,” and the SOSV Climate Tech Summit is designed to improve the prospects for all startups and all investors in the category, as well as to attract new participants.

“Startups by their very nature take risks no normal business would,” says Sean O’Sullivan, the founder and managing partner of SOSV, “and that’s doubly true for the deep tech startups inventing radical, breakthrough approaches to decarbonization. The more investment we deliver to brilliant founders, the better our chances that we will produce the innovations we need to save the planet. The SOSV Climate Tech Summit will help us speed up the exchange of insights and deepening of networks that are fundamental to the rapid growth of any startup ecosystem. As we can all see in the daily news coverage, the increasing rate of climate-related disasters requires immediate action. We really can’t move fast enough.”

The executive producers are Ned Desmond, SOSV senior operating partner and former COO of TechCrunch, and Ben Joffe, an SOSV Partner. Norm Amandi is responsible for the video production.

Sept. 26-27, 2023, From 8 a.m. to 12 p.m. PST.

The event is virtual.

SOSV’s aim is to help the climate tech startup ecosystem by convening investors, founders, corporates, policy-makers and media to hear from the leading founders and VCs in the sector. Our belief is that startups will provide many of products and technologies that will help humanity address climate change, and as a leader in the category, SOSV has a responsibility to convene and educate all the interested parties in and around the climate tech ecosystem.
