Dave Goldberg, Head of SurveyMonkey and Half of a Silicon Valley Power Couple

Dave Goldberg, the chief executive of SurveyMonkey and the husband of Sheryl K. Sandberg, the chief operating officer of Facebook, died on May 1 . He was 47. Mark Zuckerberg, chief executive of Facebook and a friend of the family, said it occurred while Goldberg was on vacation abroad with Sandberg.

Goldberg was always quick with a wisecrack, and he kept a sense of humor about being the less famous half of one of Silicon Valley’s pre-eminent power couples. Sandberg, who achieved global fame with her book “Lean In,” about the challenges faced by women in the workplace, often said she would not have been as successful in her career without his substantial assistance at home. Goldberg joined SurveyMonkey in 2009 after stints at Benchmark Capital and Yahoo. At the time, the company had 14 employees. He built it into a provider of web surveys on almost every topic imaginable, be it customer service or politics, with 500 employees and 25 million surveys created. News reports said it was valued at nearly $2 billion when it raised a round of funding in 2014.
