Vapi raises $50 million as enterprise AI voice calls surge 10-fold

Vapi has crossed a new threshold for AI voice automation: Amazon Ring chose its platform after comparing more than 40 vendors, and Vapi says enterprise business has grown 10-fold since early 2025 as more companies move support and sales calls to software agents.

The San Francisco startup raised $50 million in a Series B led by Peak XV Partners, valuing it at about $500 million after the deal, according to a person familiar with the matter. That is a sharp climb from its December 2024 Series A, when Sacra said Vapi raised $20 million led by Bessemer Venture Partners at an approximately $130 million post-money valuation.

The Ring deal shows what is changing in the market. Ring turned to Vapi in mid-Q4 2025 as it weighed whether to expand call-center capacity, lean more heavily on traditional automated phone systems or deploy AI agents that could answer customers more naturally during the holiday surge. Ring now routes 100% of its inbound calls through Vapi’s platform, and Jason Mitura, vice president of software development at Amazon Ring, said customer satisfaction scores improved after the rollout.

Jordan Dearsley, Vapi’s chief executive, said Ring selected the company because it gave engineers granular control over how the agents behaved in live customer interactions. That control has become a key selling point for enterprise buyers that want automation without surrendering oversight, especially when the software is speaking directly to customers about orders, support issues and product questions.

Vapi says it has now handled more than 1 billion calls through its platform and currently processes between 1 million and 5 million calls a day, with enterprise customers making up most of that volume. The company’s enterprise page says the system includes role-based access control, single sign-on, OAuth, an enterprise service-level agreement and compliance with SOC 2, HIPAA and PCI standards, all signals that voice AI is moving deeper into regulated and security-sensitive workflows.

The pace of adoption suggests the next phase of automation is no longer experimental. Forbes reported in January 2026 that Vapi had powered more than 500 million voice calls, served about 500,000 developers and been founded in September 2024, underscoring how fast the company scaled from a conversational AI therapist concept into infrastructure for business calls. The question now is not whether AI can answer the phone, but how much of customer service, and how many jobs around it, will follow.
