Vic Gundotra, chief of the Google+ team, confirmed his resignation in a post on the social network after eight years with the Internet giant.
Regardless of what spread on the rumor mill app spreading throughout Silicon Valley like wildifre, Gundotra explained in his resignation memo that the decision stemmed from soul searching following a personal family tragedy.
Google CEO Larry Page followed up with a Google+ post of his own thanking Gundotra, crediting the former Microsoft general manager that he "built Google+ from nothing."
You cut your teeth on our mobile apps and developer relations, turning our disparate efforts into something great. When I first used turn-by-turn navigation, it blew me away. And, walking onto the stage at I/O last year, it was amazing to see developers so excited about Google. These were vintage Vic projects.
The Re/Code report said, according to sources, that Google has already tapped its vice president of engineering, David Besbris, to replace Gundotra.
ZDNet pinged Google for confirmation and will update this post pending comment from Mountain View.
UPDATE: Google confirmed the Besbris promotion.
