JP Morgan is banking on Stacey Friedman, a former Sullivan & Cromwell litigation and regulatory partner, to head up the legal team as general counsel of the bank’s recently formed corporate and investment bank division. JP Morgan merged its investment bank and treasury and securities services divisions in July as part of an overall bank restructuring.

While at Sullivan, Friedman spent a year working full time for then-client JP Morgan as one of the principal architects of the bank’s mortgage-backed securities litigation defense. “My family calls it ‘try before you buy,’ but I think it could be seen as the world’s longest job interview,” Friedman jokes. She took on the general counsel role at the bank in August.
