San Francisco, May 3: Dave Goldberg, the chief executive of SurveyMonkey and the husband of Sheryl K. Sandberg of Facebook, died on Friday night. He was 47.

Goldberg was a serial Silicon Valley entrepreneur and venture capitalist. His death was confirmed by SurveyMonkey, which is known for its web-based survey technology. The company did not disclose the cause of death.

Mark Zuckerberg, chief executive of Facebook and a friend of the family, said it occurred while Goldberg was on vacation abroad with Sandberg.

Dave's brother, Robert Goldberg, shared news of his death in a Facebook post and urged people who knew him to post memories and pictures on Goldberg's memorial Facebook profile. Tributes poured in there and elsewhere online from hundreds of people who knew Goldberg as a mentor, colleague or friend.

"To this day, he is the leader and person by which I measure all others," Karin Gilford, a top executive at Disney ABC Television Group who worked with Goldberg at a previous start-up and at Yahoo, wrote on his Facebook page.

Goldberg lived with his wife, Sandberg, the chief operating officer of Facebook, in Menlo Park, California. They have two children. He is also survived by his mother, Paula Goldberg.
