Roelof Botha, a longtime venture capitalist and former executive at Sequoia Capital, is joining the board of SpaceX. Multiple outlets report that Botha previously worked with Elon Musk during the PayPal era in the dot-com period, and his appointment is described as a reunion with Musk after decades. Botha spent more than two decades at Sequoia Capital, where he built his reputation as a prominent investor.

According to MarketWatch, Botha will serve on SpaceX’s audit committee as part of his board role. CNBC similarly reports that he will join the SpaceX board and highlights his earlier working relationship with Musk at PayPal. Fortune also notes Botha’s history with Sequoia and his earlier connection to Musk.

The reports agree that Botha’s appointment adds another individual associated with what is often called the “PayPal Mafia” to SpaceX’s leadership structure, reflecting the company’s continued ties to investors and executives from the PayPal background.
