Vapi Hits $500M Valuation After Winning Amazon Ring Deal

AI voice startup Vapi has reached a valuation of roughly $500 million after landing a major partnership with Amazon Ring, beating more than 40 rival AI voice companies in the process.

The startup recently closed a $50 million Series B funding round led by Peak XV Partners, according to a source familiar with the deal. Investors including M12, Kleiner Perkins, and Bessemer Venture Partners also joined the round, bringing Vapi’s total funding to $72 million.

The rapid rise comes after Amazon Ring selected Vapi to manage its inbound customer support phone calls during the intense holiday shopping season last year.

According to Vapi CEO Jordan Dearsley, Ring evaluated more than 40 AI voice vendors before choosing Vapi’s technology. Today, Ring reportedly routes 100% of its inbound calls through Vapi’s platform.

Ring had been exploring several options to handle a spike in customer support demand, including expanding traditional call centers, relying more heavily on automated phone systems, or deploying conversational AI agents.

Dearsley said Vapi stood out because it gave Ring engineers detailed control over how AI voice agents behaved during live customer interactions.

Jason Mitura, vice president of software development at Ring, said the deployment improved customer satisfaction scores and allowed Ring teams to fine-tune AI experiences without depending entirely on engineering staff.

Founded by Dearsley and his University of Waterloo classmate Nikhil Gupta, Vapi originally began as an AI therapist project designed for voice conversations during daily walks.

The founders soon realized that businesses were more interested in the low-latency voice infrastructure powering the product than the therapy concept itself. That insight led them to pivot and officially launch Vapi as a developer platform in 2024.

The company now provides infrastructure tools that allow businesses to build and manage AI-powered voice agents for customer support, sales calls, appointment scheduling, and lead qualification.

Vapi says it has already processed more than 1 billion calls through its platform.

According to Dearsley, the company currently handles between 1 million and 5 million calls every day, with enterprise clients accounting for most of the volume.

Alongside Amazon Ring, Vapi’s customer list includes companies such as Kavak, Instawork, New York Life, Intuit, and ElevenLabs.

The startup also says more than 1 million developers have used its self-service platform.

Vapi is emerging as part of a broader boom in AI voice technology, competing alongside startups like PolyAI, Retell AI, and Sierra as companies race to automate customer conversations using increasingly human-like AI systems.

Dearsley said Vapi differentiates itself by focusing less on prebuilt chatbot applications and more on the infrastructure layer powering enterprise-grade AI voice systems.

The company currently employs around 100 people and plans to use the fresh funding to expand engineering, infrastructure, and go-to-market operations.

As AI voice agents rapidly move into mainstream customer service operations, Vapi’s growth highlights how conversational AI is becoming one of the hottest sectors in enterprise software.
