JPMorgan Chase & Co. Chief Operating Officer Matt Zames, the intense ex-hedge fund trader who helped clean up the bank’s London Whale debacle and was seen as a possible successor to Chief Executive Officer Jamie Dimon, is leaving with the aim of running another company.

“I’ve been in this business for almost a quarter century, and I’ve spent the vast majority of my career building businesses front to back,” Zames, 46, said in a telephone interview. “I want to get back to that, I want to face off with clients again. I love big and complicated things.”
