Vapi

Vapi is a voice-agent platform that lets companies build, deploy, and manage AI voice agents for customer support, lead qualification, appointment scheduling, and outbound sales calls. Founded by Jordan Dearsley and Nikhil Gupta — University of Waterloo classmates who went through Y Combinator with an earlier AI therapy chatbot product before pivoting into voice infrastructure — Vapi has grown into one of the most heavily used voice-AI platforms by call volume, processing between 1 and 5 million calls daily and over 1 billion calls in total across its enterprise and self-serve developer surfaces.

The company operates two product surfaces under the same platform: an enterprise sales motion for large customers (Amazon Ring, Kavak, Instawork, New York Life, Intuit) and a self-serve developer platform for engineers building voice-first applications. The dual-track approach is structurally similar to OpenAI's consumer/enterprise split and Twilio's developer/enterprise approach, and lets Vapi capture both the high-volume strategic accounts and the long tail of independent builders without forcing one onto the other's product surface.

The defining 2026 commercial milestone is Amazon Ring's decision to route 100 percent of inbound calls through Vapi after evaluating more than 40 competing voice-AI platforms. Ring's scale — millions of doorbell devices generating customer support inquiries — makes it one of the largest voice-AI deployments in any consumer hardware category, and the head-to-head selection over 40 alternatives is the kind of social proof that drives enterprise procurement decisions downstream. Other named customers (Kavak in mobility, Instawork in staffing, New York Life in insurance, Intuit in finance) show vertical breadth rather than a single-industry concentration, and signal that voice AI has crossed from pilot to production deployment in mainstream enterprise IT budgets.

Vapi's May 2026 Series B raised $50 million at a $500 million post-money valuation, led by Peak XV Partners with Microsoft's M12, Kleiner Perkins, and Bessemer Venture Partners participating. Total funding now sits at $72 million across all rounds. The valuation puts Vapi in the same tier as other voice-AI infrastructure leaders, and the M12 participation is structurally notable — Microsoft positions Azure Communication Services and its own AI voice stack as competitive products, so the M12 check signals that Microsoft sees Vapi as either complementary infrastructure or an acquisition candidate rather than a pure competitor.
