Announcing the SOSV Climate Tech Summit’s first eight speakers

Benjamin Joffe


Who knew that the climate tech ecosystem in 2022 would face such surprising challenges? Just a year ago, investors happily doubled down on climate tech startups, deploying more than $40 billion according to TechCrunch.

Now we face inflation-driven economic turmoil, war in the Ukraine, and the related instability of carbon-based energy markets. If there’s a bright spot, as Climate Tech VC recently noted, it’s the “ample climate capital in the market to stay warm through a cold snap,” thanks to the 72 climate venture and growth funds totaling $37B announced in the last 18 months.

Good news or bad, there’s no doubt that 2022 is a new chapter for climate tech startups. The SOSV Climate Tech Summit team is building an outstanding, two-day virtual program Oct. 25–26 (register — it’s free) enlisting dozens of investors and founders to address how they see the ecosystem in this new world. Is this nuclear’s moment? (Carbon capture’s? Hydrogen’s? Alternative protein’s?) We will hear about those topics and much more. At last year’s summit, attended by more than 2000 people, Bill Gates declared that the climate startup ecosystem will produce “8 to 10 Teslas.” We believe him, and we’re eager to hear which categories and companies are capturing the momentum in this new world.

We’re delighted to announce our first eight speakers.

Joining us for fireside chats with expert moderators are US Department of Energy Director Jigar Shah, who runs the $40B Loan Program Office, MIT Professor Dr. Yet-Ming Chiang, as well as two ‘climate unicorn’ CEOs: Climeworks’s Dr. Christoph Gebald, and Notco’s Matias Muchnick.

And joining us on panel discussions are Google X’s Sarah Hunter, who will join a discussion about how public policy shapes the startup ecosystem; World Fund’s Daria Saharova, who will join fellow first time climate fund general partners to discuss their outlook; Energy Impact Partner’s Shayle Kann, who will compare notes with other billion + climate fund investors; and Dandelion Energy’s Kathy Hannun, who will talk over geothermal with other geo-energy pioneers.

Below is more information about our speakers. Please register today!
