“Now is the time for a new journey. I am excited about what’s next. But this isn’t the day to talk about that,” he said.

He had been at Google for nearly eight years. Gundotra had works at Microsoft before joining Google in 2007.

Larry Page, co-founder and CEO of Google, wished him good luck and said that Gundotram 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 your hard work and passion,” he said.

He will be replaced by VP of engineering David Besbris. There were reports that Brad Horowitz, Google+’s product head, was also considered for the position.
