About
Bolna is a voice AI orchestration platform designed to help businesses build and deploy human-like conversational agents for inbound and outbound calling. Backed by Y Combinator and General Catalyst, it specializes in handling high-volume call operations with a focus on the Indian market, supporting over 10 vernacular languages including Hindi, Tamil, Telugu, and Hinglish. The platform bridges the gap between complex AI models and real-world telephony, allowing companies to automate customer service, recruitment screening, and sales recovery without sacrificing the natural feel of a conversation. The platform offers a dual-track approach for development: a no-code playground for quick setup using pre-built templates and a comprehensive set of developer APIs for deep integration. Bolna acts as an orchestrator, connecting various ASR (Automatic Speech Recognition), LLM (Large Language Model), and TTS (Text-to-Speech) providers like OpenAI, ElevenLabs, and Deepgram. It handles the nuances of live conversation, such as managing interruptions and maintaining latency under 300ms. Users can trigger calls via APIs, manage bulk campaigns, and implement human-in-the-loop features to transfer calls to live agents when complex issues arise. Bolna is particularly effective for enterprises in industries like E-commerce, EdTech, and HealthTech that need to scale their call operations. For e-commerce companies, it automates cart abandonment recovery and COD confirmations. In recruitment, it assists HR teams by conducting initial technical screenings and interviews at scale. The platform is also built for developers who need to integrate voice capabilities into existing workflows using tools like Zapier, Make.com, or custom Python and JavaScript environments. What sets Bolna apart is its deep optimization for Indian languages and accents, ensuring high accuracy in a diverse linguistic landscape. It provides an open stack where businesses can switch between 20+ different models for transcription or voice generation to optimize for cost or quality. Furthermore, it addresses enterprise security needs with options for on-premise deployment and regional data residency in both India and the USA. The transparent, usage-based pricing model further differentiates it by allowing companies to pay for the exact components used in each call.
