Chris Sacca’s Venture Firm Is Raising a Second Fusion Fund

Chris Sacca’s venture firm is doubling down on fusion as it seeks to raise a new fund dedicated to the next-gen nuclear technology.

“We are out talking with investors about our second fusion fund,” the Lowercarbon Capital co-founder said at the SOSV Climate Tech Summit on Thursday. Lowercarbon, which has backed fusion leader Commonwealth Fusion Systems, as well as upstarts Princeton Stellarators and Xcimer, announced its first nuclear fusion-focused fund of $250 million in 2022.

The venture firm aims to raise a bigger fund this time, according to a person familiar with the matter.
