Developer-first voice AI platform for building and scaling enterprise voice agents with sub-500ms latency.
Vapi provides a comprehensive developer-first infrastructure for deploying AI voice agents at enterprise scale. The platform handles telephony internals, offers sub-500ms latency, supports over 100 languages, and includes built-in guardrails to prevent model hallucinations and ensure data integrity.
The platform features Flow Studio for visual agent building, Assistants and Squads for multi-agent orchestration, knowledge base integration, and call analysis with structured summaries. Founded by University of Waterloo classmates Jordan Dearsley and Nikhil Gupta, Vapi grew out of an AI therapist project and a previous Y Combinator-backed startup called Superpowered.
