From lean startups to spiritual holding companies: The education of Eric Ries

Eric Ries, who inspired many a founder with his book The Lean Startup and went on to found the Long-Term Stock Exchange, joins Amy Cortese on this Agents of Impact podcast.

Human flourishing, he says, not profit maximization, should be the true purpose of companies. He has some ideas of how to build organizations that can resist both inside temptations and outside pressure to betray their missions.
