Amazon Ring chose AI voice platform Vapi from a pool of more than 40 vendors to handle all inbound calls, a move that spurred a $50 million Series B round and pushed the startup’s valuation to roughly $500 million. The deal, led by Peak XV Partners and backed by Microsoft’s M12, Kleiner Perkins and Bessemer, marks a milestone for Vapi, whose technology now powers millions of daily calls for Ring and a roster of other enterprise customers.
Amazon Ring, grappling with a surge in customer‑support calls during the 2023 holiday season, evaluated over 40 AI voice vendors before selecting startup Vapi to route its inbound phone traffic. Today, Ring directs 100 percent of its inbound calls through Vapi’s platform, a deployment that helped the company secure a $50 million Series B round at an estimated $500 million valuation.
Ring’s partnership with Vapi began in mid‑Q4 of last year, when the company weighed options between expanding traditional call‑center capacity, relying on conventional automated phone systems, or deploying AI agents capable of natural conversation. Vapi chief executive Jordan Dearsley said Ring favored Vapi because the platform gave engineers granular control over AI agent behavior in live interactions. Jason Mitura, Ring’s vice president of software development, confirmed that customer‑satisfaction scores rose after the rollout and that teams could fine‑tune the AI experience without depending on engineering resources.
Founded by Dearsley and his University of Waterloo classmate Nikhil Gupta, Vapi emerged from an AI therapist Dearsley built in 2023 for personal use during walks. After a stint at Y Combinator with the productivity startup Superpowered, the duo pivoted to voice infrastructure, launching Vapi publicly in 2024. The platform offers tools for building, deploying and managing voice agents across use cases such as support, lead qualification, appointment scheduling and outbound sales.
Vapi now boasts more than one billion calls handled through its service, processing between one and five million calls daily, with enterprise clients accounting for the bulk of that volume. In addition to Amazon Ring, the startup counts Kavak, Instawork, New York Life, UnityAI, Cherry and Intuit among its customers. A self‑serve developer portal has attracted over a million developers, giving Vapi a battle‑tested foundation before landing its first major enterprise contract.
The Series B round, led by Peak XV Partners, also included Microsoft’s M12, Kleiner Perkins and Bessemer Venture Partners, bringing Vapi’s total funding to $72 million. An investor source said the company now runs an annual recurring revenue stream in the “healthy” eight‑figure range. Vapi plans to use the fresh capital to grow its engineering, infrastructure and go‑to‑market teams, adding to its current staff of roughly 100 employees.
Unlike many AI voice competitors that market pre‑packaged applications, Vapi focuses on the underlying infrastructure and orchestration layer that lets enterprises control reliability, compliance and model behavior. Dearsley summed up the challenge: “The golden problem is taking this indeterminate beast that is a model and taming it.” As the market sees newcomers like Sierra, Decagon, PolyAI, Bland, Retell and ElevenLabs vie for share, Vapi’s emphasis on control and scalability positions it as a key player in the next wave of voice‑first customer experiences.
