Vapi

Overview Vapi is a platform for developers to build, test, and deploy voice AI agents that handle phone calls. It replaces the need to build telephony and voice infrastructure from scratch. The platform handles orchestration, real-time monitoring, and enterprise-grade configurability. Teams at companies like Kavak and Ring use Vapi to automate lead qualification, customer support, and appointment scheduling at scale. Key Benefits Go from prompt to production in as little as two weeks — Ring deployed 100% of inbound volume on Vapi within that timeframe. Support up to millions of calls with sub-500ms latency, backed by a 99.9% uptime SLA for enterprise clients. Over 1 billion calls supported and more than 2.5 million agents launched on the platform. Built-in AI guardrails prevent model hallucinations and ensure data integrity during conversations. SOC 2, HIPAA, and PCI compliant out of the box, with optional add-on compliance tiers. API-first design with integrations for custom voices, models, and telephony providers. How It Works You configure your voice agent's voice, conversation flow, telephony settings, and integrations through the Vapi dashboard. Once configured, you deploy the agent and Vapi handles infrastructure, scaling, and real-time monitoring. You track performance across every call, surface issues, and iterate on the agent's behavior continuously. Use Cases Lead qualification teams — Automate inbound lead discovery calls with smart multi-turn conversation agents. Customer support operations — Deflect inbound support calls to AI agents while maintaining CSAT scores. Healthcare providers — Deploy compliant voice agents handling 1M+ calls per month across dozens of use cases. Marketplace platforms — Scale customer outreach and service, as demonstrated by Kavak's 5x revenue growth and 250k monthly calls. Staffing agencies — Automate candidate screening and appointment scheduling via voice. Why Choose This Product Vapi is best suited for engineering teams at mid-market and enterprise companies who need reliable, compliant voice AI at scale. The platform requires upfront configuration and a paid plan to get started, with additional costs for HIPAA compliance, zero data retention, and custom call concurrency beyond 10 lines.
