Dick Costolo plans to step down from Twitter board by end of year or when new CEO is appointed
Dick Costolo Reportedly Plans to Step Down From Twitter's Board — Dick Costolo, the former chief executive of Twitter, plans to leave the company's board of directors by the end of the year …
Context & Ripple Effects
When Dick Costolo handed the Twitter CEO job to Jack Dorsey as interim chief in June, he stayed on as a director — an arrangement he himself flagged as awkward, describing what it was like to serve on a board alongside two former CEOs. A day before this report, Bloomberg reported the board was considering a shuffle that included his exit, so this NYT account confirms the direction of travel.
The significance is timing: Costolo ties his departure either to the end of the year or to the appointment of a permanent successor, effectively setting a clock on the CEO search while removing the outgoing chief from oversight.
First-order effects
- Twitter's board will lose the director who ran the company until July, leaving Dorsey as the only former CEO in the room and clearing one obstacle to his own permanent candidacy — which, per the June Business Insider interview, he declined to deny interest in.
Second-order effects
- With Costolo gone, the remaining directors must decide whether to formalize Dorsey's role or run a wider search, and any incoming CEO inherits a board freshly reshuffled rather than one anchored by its predecessor — shifting internal power toward whoever chairs the succession process.
Third-order effects
- Costolo has already argued publicly that going public accelerated short-term thinking at Twitter; if the pattern holds, founder-era executives exiting boards entirely rather than lingering as overseers becomes the template for big-consumer-internet successions, and boards lose institutional memory faster in exchange for cleaner mandates.
The trend: Consumer-tech CEO successions are trending toward the outgoing chief making a clean break from governance rather than staying on as a bridge director.
