Vapi
What is Vapi?
Vapi is a voice agent platform for building, testing, and deploying phone agents that handle real customer calls at scale. Teams use it for customer support, lead qualification, appointment scheduling, and outbound sales, with sub-500ms latency and orchestration built in. The platform has handled over one billion calls and is used by enterprises including Amazon Ring, Intuit, and ServiceTitan.
The product is developer-first but accessible through a dashboard UI as well. You configure voice, conversation flow, telephony, and integrations in one place, then connect 200+ built-in models or bring your own for speech-to-text, LLM, and text-to-speech. Live tool calling and MCP support let agents fetch data and trigger actions mid-call.
Vapi targets engineering teams shipping production voice agents and enterprises that need compliance, uptime guarantees, and dedicated support. Scale customers get SSO, RBAC, SOC 2, HIPAA, PCI, data residency, and a dedicated account team.
