What ex-Twitter chief Dick Costolo is doing next, and why

Six months after stepping down as Twitter CEO, Dick Costolo said Tuesday he’s working on a fitness start-up and is joining venture capital firm Index Ventures as a partner.

In a series of tweets, Costolo didn’t give details on what types of companies he’ll focus on at Index, just saying he’ll invest in entrepreneurs and work with existing portfolio companies. Costolo said he’s gotten to know the firm though a friend, partner Danny Rimer.

In an email to CNBC on Tuesday morning, Costolo said his years running Twitter through its IPO helped him discover an interest in fitness.
