I don't have any direct knowledge, but the gossip flying around internally at the time was that a big part of George leaving Twilio was because he wanted the CEO role, but knew Jeff wasn't going to leave and give it to him.

That was gossip, of course; sure, George may have decided back then that -- even with all the growth he drove -- Twilio wasn't going anywhere long-term.

The fact that George has not taken on a CEO role since tells me that it probably wasn't a driving factor for him. That's conjecture though. I think that role would be available to him at a lot of strong companies if that was his goal.
