Vapi

Vapi positions itself as both a self-serve voice agent platform (for developers) and an enterprise deployment platform that aims to move teams from prototype to production more quickly than building a full voice stack in-house. Vapi’s core workflow is: developers define an assistant/voice agent, connect it to telephony and integration points, and then operate it in production while tracking performance and reliability. Product-wise, Vapi presents a unified platform for orchestration and operations, along with developer tools such as a CLI and SDKs (and examples). For enterprises, Vapi emphasizes low latency and scalability, model/provider flexibility (so teams can tune behavior and swap components), and enterprise controls including SSO/OAuth/RBAC and support/SLA-oriented deployment options. Business model: Vapi charges for usage and/or subscriptions to access its hosted voice/agent infrastructure and enterprise features, while also exposing an API so customers can integrate voice agents into their existing applications and systems. In this model, Vapi monetizes the infrastructure layer (voice orchestration, runtime reliability, observability, and enterprise deployment support) while customers supply the business logic and tool/integration endpoints used by their voice agents. Strategic position (as of 2026-09-01): Vapi has raised a $50M Series B (May 12, 2026) led by Peak XV with participation from investors including M12, Kleiner Perkins, and Bessemer Venture Partners, and it reports operational scale milestones such as “1,000,000,000 calls supported” and 99.9% enterprise uptime on its site. It also highlights enterprise customer deployments such as Amazon Ring, and recent product/security and operational updates including an “Enhanced Security Mode” blog post and a disclosed supply-chain incident response regarding malicious npm package versions in the Vapi GitHub organization.
