David Goldberg, CEO of SurveyMonkey and husband of Facebook COO Sheryl Sandberg, died suddenly Friday night. The cause of death has not been released, though sources say he died after collapsing while exercising on vacation.
Goldberg was 47 and had two children with Sandberg. His brother, Robert Goldberg, announced the news in a post on Facebook, requesting that people share their memories of David via the site.
"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.
There has also been an outpouring of support and condolences across the tech community, including from Facebook CEO Mark Zuckerberg, who called Goldberg "an amazing person."
Goldberg had a long, varied career, which spanned companies like Capitol Records and Yahoo before he ultimately became chief of SurveyMonkey. As CEO there, Goldberg oversaw a company with about 500 employees, which has grown to become a recognizable Web-based survey platform. The service is used by more than 20 million people worldwide and receives 2.8 million survey responses every day, with 473,000 surveys deployed every month.
He began dating Sandberg in 2002, and they married two years later. Though both had successful careers, Sandberg often discussed how they divvied up household responsibilities. Their partnership was key to her successful career, she has said.
One of the keys to their success was that they both left work at about 5:30 p.m. every day. Goldberg told The Los Angeles Times two years ago that both he and Sandberg worked hard to ensure their home life didn't suffer despite their high-profile jobs. "I am at home with my kids from 6 to 8. If I have a work dinner, I'll schedule to have dinner after 8. But we're working at night," he said. "You'll get plenty of emails from me post-8 p.m. when my kids go to bed."
Tech VIPs paid tribute to Goldberg on Saturday.
"Dave's passing is unfathomable," Jim Lanzone, chief executive of CNET parent CBS Interactive, said of his longtime friend. "There was no one like him. A lot of people try to be as good a person as Dave Goldberg, but no one else I know pulls it off. It's just a huge, huge loss for family, friends and our community as a whole."
Twitter CEO Dick Costolo, Salesforce CEO Marc Benioff, PayPal co-founder Max Levchin and former MySpace President Jason Hirschhorn offered elegies via Twitter:
