Steve Jurvetson, a founding partner of one of the best-known venture capital firms in Silicon Valley and a board member of Tesla and SpaceX, is leaving the firm after it began an investigation into his behavior with women, the firm told investors on Monday.

“As of today and by mutual agreement, Steve Jurvetson will be leaving DFJ,” said a confidential letter sent to investors in the venture capital firm, Draper Fisher Jurvetson, and obtained by The New York Times.

It continued, “DFJ’s culture has been, and will continue to be, built on the values of respect and integrity in all of our interactions.”

The firm’s spokeswoman, Carol Wentworth, confirmed his departure, and a Tesla spokeswoman said he is taking a leave of absence from the Tesla and SpaceX boards “pending resolution of these allegations.” Last month, the firm said it became aware of “indirect and secondhand allegations” about Mr. Jurvetson and was looking into them. The acknowledgment came after Keri Kukral, a tech entrepreneur, wrote on Facebook: “Women approached by a founding partner of Draper Fisher Jurvetson should be careful. Predatory behavior is rampant.”
