  • Company: J.P. Morgan Chase & Co.
  • Revenue: $108.2 billion

Reeling after a $6 billion loss in the London Whale debacle, last year the top bank rearranged its executive lineup. Lake emerged as a top player in November, taking the CEO job and instantly becoming one of the most powerful women on Wall Street. The accountant by training was previously CFO of the company's consumer businesses and served as controller of its investment banking business. In her new job, U.K.-raised Lake works closely with CEO Jamie Dimon and is one of only two women on the bank's operating committee.
