Prosper Marketplace Inc.'s Chris Larsen is stepping down as chief executive. He remains the San Francisco company's chairman.
Prosper, the first person-to-person online loan facilitator in the U.S., has hired Dawn Lepore as its interim CEO. Lepore was previously chairman and CEO of drugstore.com and vice chairman of Charles Schwab Corp.
"Now is the time to embrace the next phase of the company's evolution," Larsen said in a press release. "As chairman, I look forward to working closely with the executive team to build a truly innovative consumer credit company."
Before launching Prosper in 2006, Larsen headed E-Loan Inc.
Eric Schwartz, a private-equity investor and veteran of Goldman Sachs, is joining Prosper's board, the company also said.
