How do you find your first customers? It’s a question first-time founders are often flummoxed by. But Keith Krach has developed a tried-and-true strategy—starting during his days at Ariba (which sold for billions), and extending into his current time as chairman of Docusign. In this special live edition of Problem Solvers, taped at Entrepreneur Live in Los Angeles, Keith explains how to turn a company’s first customers into valuable ambassadors. (This episode originally aired 2/26/18. At the end, we catch up with Keith for an update in 2019.)
