Twitter Ex-CEO Costolo Plans Fitness Startup, Joins VC Firm - Bloomberg

Dick Costolo, who resigned as Twitter Inc.’s chief executive officer last year, is starting a new company -- one that’s focused on personal fitness.

Taking to the social-media service he helped build, Costolo tweeted a couple of screenshots of his announcement. He and Bryan Oki, who runs a health and wellness consulting firm, will work together to create a software platform aimed at helping motivate users to work out.
