UPDATE: A source close to the family confirms to NBC News that Goldberg was on vacation with family and friends in Mexico and he collapsed while exercising. Efforts to revive him both at the scene and at a local hospital were unsuccessful. The New York Times reported that Goldberg died of head trauma after collapsing in the gym of the Four Seasons Resort near Punta Mita.

Dave Goldberg, CEO of SurveyMonkey and husband of Facebook COO Sheryl Sandberg, has died at age 47.

Dave, described by The New York Times as a "serial Silicon Valley entrepreneur and venture capitalist," passed away suddenly on Friday night, his brother Robert Goldberg announced on his Facebook page on Saturday morning. The cause of his death was not revealed.

"It's with incredible shock and sadness that I'm letting our friends and family know that my amazing brother, Dave Goldberg, beloved husband of Sheryl Sandberg, father of two wonderful children, and son of Paula Goldberg, passed away suddenly last night," Robert wrote. "In this time of sorrow, we mourn his passing and remember what an amazing husband, father, brother, son and friend he was. No words can express the depth of loss we feel, but we want his children to learn how much he meant to all of you."

"In lieu of donations, we want to celebrate his life in a manner that respects the family's privacy as they cope with this tragic, life changing event," he added. "Sheryl, their children, and our family would be grateful if people would post their memories and pictures of Dave to his Facebook profile.

Facebook CEO Mark Zuckerberg said on his own page that Dave was "an amazing person," adding, "I am glad I got to know him."

"My thoughts and prayers are with Sheryl and her family," he said. "I hope friends will join me in celebrating his life by sharing your memories of Dave on his proflle, as his brother Rob suggests."

Twitter CEO Dick Costolo tweeted his condolences.

SurveyMonkey also paid tribute to the online poll company's late leader.

"We are deeply saddened to announce that Dave Goldberg passed away suddenly last night," read a post published on the group's Facebook page. "Dave's genius, courage and leadership were overshadowed only by his compassion, friendship and heart. His greatest love was for his family. Our sympathy goes out to them and to all who were touched by this extraordinary man. We are all heartbroken."
