Lowercarbon’s Chris Sacca to speak on his $1.15 billion funds and their progress to “unf**k” the planet

According to investor Chris Sacca, “The climate is f’d.” The billionaire founder of Lowercase Capital is known for his investments in Uber, Twitter, Instagram, Stripe, and other famed unicorns. He came out of retirement in 2021 to “unf**k the planet” with Lowercarbon Capital, his new venture firm. Armed with $1.15 billion in capital across two funds, 1.6 million Twitter followers, and an unlimited supply of carbon-free F bombs, can this software VC kick it in climate tech?

Chris Sacca explored this question and others at the SOSV Climate Tech Summit (Oct. 25-26). You can hear what he has to say in the recorded session below.

Lowercarbon Capital is making some of the boldest deals in this space. Their portfolio includes everything from lithium mining and electric planes to kelp farming and cooking oil to handheld fusion reactors and carbon capture. And yes, like the yeehaw Texan billionaire from Neal Stephenson’s latest novel (Stephenson also joined us at the Summit), cowboy couture Sacca has funded geoengineering (though only as non-profit research for now). 

What specific milestones and business models does Lowercarbon Capital target in this wide-ranging climate tech portfolio? Has Sacca ever met a climate tech company too bold for him? What should his friends in the White House be doing about climate change?

Interviewing Chris Sacca for the SOSV Climate Tech Summit was Connie Loizos, TechCrunch’s Silicon Valley Editor.
