Dave Goldberg, the successful Silicon Valley entrepreneur and CEO of SurveyMonkey, died unexpectedly Friday night, his brother confirmed in a Facebook post. He was 47.

“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,” Robert Goldberg wrote in part.

“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: Sheryl, their children, and our family would be grateful if people would post their memories and pictures of Dave to his Facebook profile,” he added.

Goldberg reportedly died of severe head trauma in an exercise accident at a private villa in Punta Mita, a Mexican state official told the Associated Press on Monday. According to the official, he was found at about 6:30 p.m. in the gymnasium lying by a treadmill bleeding severely from back of his head. Goldberg presumably had slipped on the treadmill and hit the machine, said the official, who wished to remain anonymous.

Goldberg, who was married to Facebook Chief Operating Officer Sheryl Sandberg, reportedly still had vital signs when he was discovered, but later died at a hospital in Nuevo Vallarta. He and his wife resided in Menlo Park, California, with their two children, according to the The New York Times.

Sandberg, 45, also founded the “Lean In” movement, which encourages women to pursue their ambitions and succeed in the workforce. Goldberg’s death comes less than two months after Sandberg honored her husband on her Facebook page, launching LeanIn.Org’s #leanintogether campaign, “celebrating men who lean in for equality.”

“The man I most want to celebrate is my husband Dave Goldberg,” she wrote below a sweet photo of the couple (seen above) she said was taken on the day they got engaged. “I met Dave over 15 years ago and we immediately became the best of friends. He was the first person to show me the Internet, the kind of friend who shows up to help you move apartments (read: bad pre-Dave breakup), and always made me feel like I was home no matter where I was.”

Years later, we dated, married, and now we have two amazing children. He is a 50/50 partner at home and a dedicated father (although not sure my kids needed to learn poker at ages 4 and 6). He enables my career; insisting that I join Facebook when our daughter was just 6 months old and doing more than his share at home as I ramped up in my new job. I wrote in Lean In that the most important decision a woman makes is if she has a life partner and who that life partner will be. The best decision I ever made was to marry Dave.”

Memorials quickly poured in for the venture capitalist and Silicon Valley entrepreneur.

“Dave’s genius, courage and leadership were overshadowed only by his compassion, friendship and heart. Our sympathy goes out to them and to all who were touched by this extraordinary man. We are all heartbroken,” SurveyMonkey said in a statement, per the Times.
