Vic Gundotra release this statement:
Today I'm announcing my departure from Google after almost 8 years…I have been incredibly fortunate to work with the amazing people of Google. I don’t believe there is a more talented and passionate collection of people anywhere else. And I’m overwhelmed when I think about the leadership of and what he empowered me to do while at Google. From starting Google I/O, to being responsible for all mobile applications, to creating Google+, none of this would have happened without Larry’s encouragement and support.
Google also provided a statement from CEO Larry Page who noted Vic was instrumental in building Google+, mobile apps, developer relations and more: “Vic built Google+ from nothing. There are few people with the courage and ability to start something like that and I am very grateful for all his hard work.”
