Stanton spent nearly six years with Twter, overseeing its global media operations and international expansion. She previously worked in the Obama administration as director of citizen participation for the White House and special advisor to the State Department's office of innovation.

Stanton earned her tech stripes in six years with Google, including principal for new business development. That followed a stint at Yahoo.

The Twitter departures were confirmed by CEO Jack Dorsey, who hit "inaccurate press rumors" in noting the exiting execs, a group that includes Alex Roetter (head of engineering), Skip Schipper (HR head) and Kevin Weill (head of product). "All four will be taking some well-deserved time off," said Dorsey. "I'm personally grateful to each of them for everything they've contributed to Twitter and our purpose in the world."

Stanton said via Medium that the job was the "opportunity of a lifetime."
