Bolna is a voice AI platform for building, testing, deploying, and scaling conversational voice agents that place and receive phone calls with human-like, multilingual intelligence. The platform pairs a no-code Agent Studio with a Bearer-authenticated REST API (api.bolna.ai) covering agents, outbound and inbound calls, CSV batch campaigns, executions and transcripts, phone-number purchasing and search, SIP trunks, knowledge bases (RAG over PDFs/URLs), dispositions/extractions, providers (ASR/LLM/TTS credentials), voices, violations, and multi-tenant sub-accounts. Bolna integrates 20+ ASR, LLM, and TTS models (OpenAI, Azure, Anthropic, ElevenLabs, Deepgram) and telephony providers (Twilio, Plivo, SIP), and ships a hosted MCP server, an official Agent Skills collection, a Go CLI, and an open-source Python agent framework. Backed by Y Combinator and General Catalyst; strong focus on Indian-language (Hinglish, Hindi, Tamil, Telugu) voice agents with India data residency.
