- Microsoft’s M12, Kleiner Perkins, and Bessemer Venture Partners also participated; total funding is now $72 million.
What Happened
AI voice infrastructure startup Vapi raised a $50 million Series B led by Peak XV Partners at a roughly $500 million post-money valuation, TechCrunch reported on Tuesday. The round closed after Amazon Ring evaluated more than 40 AI voice vendors during the 2025 holiday-season call surge and selected Vapi to handle its inbound phone traffic. Ring now routes 100% of its inbound customer-support calls through the platform.
Why It Matters
The Amazon Ring deal is a tier-one enterprise reference for what has become a crowded AI voice category. Competitors include Retell AI, Bland AI, and integrations from Twilio, Vonage, and AWS. Ring picking a venture-stage startup over established communications-platform vendors signals that the category’s evaluation criteria have shifted toward latency, controllability, and the granularity of agent behaviour rather than vendor scale.
The round also gives a clean public valuation data point in a part of the AI stack where comparable transactions have been opaque. PolyAI raised at roughly $500 million in 2024 against materially less deployment scale; Retell raised a Series A in 2025 at a reported $250 million.
Technical Details
Vapi was founded in 2024 by University of Waterloo classmates Jordan Dearsley and Nikhil Gupta, who had previously gone through Y Combinator with a productivity startup called Superpowered. The platform began as an AI therapist Dearsley built in 2023 for daily-walk conversations; the pair pivoted after discovering startups wanted the low-latency voice infrastructure underneath. The company says it has now handled more than 1 billion calls and currently processes between 1 million and 5 million calls per day, with enterprise customers accounting for the majority of volume. Vapi’s self-serve developer platform has been used by more than 1 million developers.
Jason Mitura, vice president of software development at Amazon Ring, said Ring’s customer satisfaction scores improved after deploying Vapi, with teams able to tune AI-agent behaviour without engineering involvement. “A lot of AI tools promise great outcomes — Vapi has delivered on them,” Mitura told TechCrunch.
Who’s Affected
Vapi’s enterprise customer list, per the company, includes Amazon Ring, Kavak, Instawork, New York Life, UnityAI, Cherry, and Intuit. Investors in the Series B include Peak XV Partners, Microsoft’s M12, Kleiner Perkins, and Bessemer Venture Partners, bringing Vapi’s total funding to $72 million. Dearsley said the company is at an annual recurring revenue run-rate in the “healthy” eight figures, per a TechCrunch investor source. For enterprise contact-centre operators evaluating AI voice, the deal is a forcing function: vendors must now match Vapi’s combination of latency, controllability, and deployment scale or accept being out-competed on procurement.
What’s Next
Vapi plans to use the proceeds to expand its enterprise go-to-market function and continue developer-facing platform investments. Dearsley framed Vapi’s wedge as having been “battle-tested at significant scale before we signed our first major enterprise customer.” The company has not disclosed a target headcount or specific product roadmap, though additional vertical-specific agent templates and expanded multi-lingual support are commonly cited next steps in the category. Vapi joins a peer set — Retell, Bland, ElevenLabs Conversational — likely to be among the most-watched private AI companies through 2026.
