AI voice startup Vapi hits $500M valuation after winning Amazon Ring over 40 rivals

Amazon Ring, facing a surge in customer-support calls during last year’s holiday season, evaluated more than 40 AI voice vendors before choosing startup Vapi to handle its inbound phone traffic. Today, Ring routes 100% of its inbound calls through Vapi’s platform. That deployment helped Vapi raise a $50 million Series B led by Peak XV Partners at a valuation of around $500 million after investment, according to a person familiar with the matter.
