Founding Story
John Wolthuis co-founded Twilio in 2008. He architected the initial telephony backend that allowed developers to send text messages and make phone calls using a simple web API. By completely hiding the incredibly complex, legacy telecom infrastructure behind clean code, Wolthuis built the technical foundation that allowed Twilio to rapidly dominate the developer communications market.
