B Capital, the global multi-stage investment firm co-founded by Facebook co-founder Eduardo Saverin, has announced the final close of B Capital Ascent Fund III at its hard cap of $500 million in aggregate commitments. The fund was oversubscribed and drew capital from both existing and new limited partners, according to the firm, and represents close to double the $254 million raised for its predecessor, Ascent Fund II, which closed in July 2022.
