No More Moats: How Harmony Reached 50 Customers Without a Single Salesperson | Ran Ribenzaft (Harmony)

Description

Ran Ribenzaft, Co-Founder and CTO of Harmony (and formerly founder and CTO of Epsagon, sold to Cisco for $500M), is an unusual CTO: 90% of his time goes to Go-To-Market. In its first year Harmony reached more than 50 customers — with no salesperson at all to start. This episode is a practical master-class on what happens when technology and product are no longer a moat: how to run 100 discovery calls with no product, how calls turn into data research, and what's actually left for you to sell.
