Vapi raises $50M to expand voice AI infrastructure platform

Voice AI startup Vapi raised $50M in a Series B led by Peak XV Partners, bringing total funding to $72M. Its platform powers 2.7M AI agents that have handled over 1 billion calls for clients including Amazon Ring.

Vapi raises $50M to build voice AI that sounds natural on customer calls

Voice AI startup Vapi Inc. closed a $50 million Series B funding round led by Peak XV Partners, with backing from Y Combinator, Microsoft's M12 venture fund and Kleiner Perkins. The company now has $72 million in total funding.

Vapi builds the infrastructure that connects AI language models like OpenAI's GPT and Anthropic's Claude to voice systems. The platform handles the technical work that makes conversations feel natural: low-delay responses and the ability for callers to interrupt without awkward pauses.

The company supports over 1 million developers running 2.7 million unique AI agents that have handled more than 1 billion calls to date.

Where voice AI is already working

Vapi's customers use the platform to replace traditional call centers, automate screening workflows and handle inbound customer service at scale. Amazon Ring deployed Vapi to handle 100% of its inbound support volume and went from zero to production in two weeks.

The strongest customer traction has come from financial services, healthcare, insurance, automotive and workforce management sectors.

Voice agents now handle tasks that previously required human operators: hotel reservations, restaurant orders, shipment tracking and candidate screening through simulated dialogue.

What the funding targets

Vapi plans to invest in three areas: distribution (getting the product to the right customers), delivery (reducing the time from decision to deployment) and core infrastructure (adding governance, security and guardrails for every call).

CEO Jordan Dearsley said the core challenge for most businesses is that their customer experience has deteriorated despite decades of investment. "The real unlock is building agents for your customers that feel human," he said.
