Vapi

Vapi is a developer-first voice AI platform for building, testing, and deploying conversational voice agents that handle inbound and outbound phone calls at enterprise scale.

Founded in 2020 by Jordan Dearsley (CEO) and Nikhil Gupta, and launched publicly on Product Hunt in March 2024, Vapi (Y Combinator-backed) provides tools for companies to build, deploy, and manage voice AI agents across customer support, lead qualification, appointment scheduling, and outbound sales. The platform orchestrates speech-to-text, large language models, and text-to-speech with native telephony integration for inbound/outbound calls, real-time monitoring, and an API-first architecture that lets developers bring their own model and voice providers. Vapi offers enterprise features including SSO/OAuth, RBAC, AI guardrails, and SOC 2/HIPAA/PCI compliance, with sub-500ms average latency and 99.9% uptime. The company reports having surpassed 1 billion calls, 2.5M+ agents launched, and 750K+ developers. Named customers include Amazon Ring, Intuit, ServiceTitan, and New York Life. In May 2026 Vapi raised a $50 million Series B led by Peak XV Partners at roughly a $500 million valuation, bringing total funding to about $72 million.
