Vapi is a developer voice pipe that forces you to wire your own STT, LLM, TTS, and telephony while paying stacked vendor bills.
Trusted by leading enterprises and backed by institutional funds and ecosystems

















You set the autonomy mode per teammate and per responsibility—automated where routine, approval-gated where consequential.
