Vapi Raises $50 Million Series B to Scale Enterprise Voice AI Platform

New updates have been reported about Vapi.

Vapi has raised $50 million in Series B funding after reporting a 10x increase in enterprise ARR, positioning the company to expand its voice AI platform for large-scale customer interactions. The round, led by Peak XV with participation from M12, Kleiner Perkins, Bessemer Venture Partners, and existing investors, lifts Vapi’s total funding to $72 million and underscores investor conviction that most future customer calls will be handled by AI agents rather than humans.

Vapi’s platform enables engineering teams to build, deploy, and manage low-latency voice agents that can replace or augment contact centers, automate high-volume workflows, and navigate complex processes in sectors such as financial services, healthcare, insurance, automotive, and workforce management. The company reports more than 1 million developers on its platform, over 2.7 million unique agents created, and more than 1 billion calls processed, with enterprise customers including Amazon Ring, Kavak, ServiceTitan, New York Life, and Intuit using Vapi for use cases like inbound support, collections, candidate screening, and simulated sales coaching.

Executives at Amazon Ring say 100% of their inbound support volume now runs through Vapi, citing rapid time-to-production and improved customer satisfaction scores as key outcomes, while Vapi’s CEO frames the platform as a way for businesses to deliver customer experiences that feel human at scale. The company’s next phase of investment will focus on reliability, governance, and predictability, including tighter uptime guarantees, controlled latency under load, and call-level monitoring with guardrails and escalation paths, reflecting the higher-stakes workflows enterprises are shifting to AI.

Vapi’s origins trace back to an internal voice-based AI therapy experiment that failed as a product but proved the underlying infrastructure, leading to a public launch in 2024 and fast adoption among developers. With nearly $3 trillion in global sales estimated to be at risk in 2026 due to poor customer experiences and traditional chatbots failing to improve satisfaction scores, Vapi is positioning its developer-first, API-driven platform as a core infrastructure layer for businesses seeking measurable, outcome-driven voice interactions at scale.
