Sivak replaces interim CTO Chris Willey, who in turn replaced Vivek Kundra, who exited the Fenty administration for a top federal job in the Office of Management and Budget.

Like transportation director Gabe Klein, Sivak is coming from well outside the governmental sphere. He is a founder of software firm InQuira—an Silicon Valley outfit that has done projects for the like of Nokia, T-Mobile, and the British Ministry of Defense.

"I'm more of an innovator than anything else," he said at a One Judiciary Square press conference this morning.
