SOSV founder says climate investing is a ‘war effort’ as firm closes $306M fund

Climate /

For the firm that calls itself “the first check in deep tech,” the last check for SOSV’s latest $306 million fund took a bit longer than founder Sean O’Sullivan would have liked. That’s probably less a reflection on the firm than an indictment of the macroeconomic environment: Ask any VC, and they’ll tell you the
