This week we speak to Spencer Rascoff, chief executive of US property website Zillow.
Going to a Rolling Stones concert has inspired generations of teenagers to pick up a guitar, but for Spencer Rascoff it was instead the catalyst for a life in business.
As a teen, Spencer was lucky enough to go backstage at a number of the band's gigs in the early 1990s.
But rather than marvelling at Mick Jagger, Keith Richards and the rest of the group, he says he was fixated on the teeming personnel running around to keep the entire show on the road.
"I saw the tour producer as the chief executive, and the band and the show was the product," says Spencer, now 43.
"That was a formative experience for me, I was fascinated by the business of music."
Spencer was able to go backstage at the concerts because his dad Joseph was a business manager and tour producer for the Stones, and a host of other top acts including U2, David Bowie and Paul Simon.
