Origin of the Entrepreneurial Drive

Dave Sifry has founded nine companies, including Technorati and Linuxcare, raising more than $170 million along the way. In this episode of Built to Sell Radio, he reveals how he went from being worth more than $100 million on paper to watching that value disappear — and what he'd do differently if he had the chance again.

Despite those scars, Sifry has built an extraordinary career. He has founded nine companies and today is founder and CEO of Warmstart, a platform that helps entrepreneurs turn old contacts into new business.
