David Goldberg might be the husband of Sheryl Sandberg, Lean In author and one of Forbes most powerful women in business but his own trajectory – which includes leading a Silicon Valley start-up during the Napster era and heading up SurveyMonkey, an online survey site that was valued at $US1 billion – is no less fascinating. I interviewed Goldberg, who was in Sydney to launch Survey Monkey’s new Asia-Pacific office for Renegade Collective magazine, and his generous answers were baffling in light of the fact that he must have suffered some serious lack of sleep. The issue, which also includes a great feature on Misty Copeland, the first African-American female soloist for the American Ballet, is available in Australia now.
