Built, not rented
We own the stack others rent.
Most voice-AI startups are a thin wrapper over third-party APIs. We built every layer ourselves — so we're faster, cheaper, and far harder to copy.
Layer 01 · Voice
MynaTTS
Our own in-house OmniVoice-fast Indic speech engine — 22 Indian languages + English, ~100ms block-streaming TTFA, instant zero-shot voice cloning & voice-design, built-in noise suppression.
Others rent ElevenLabs or Cartesia, billed per minute.
Layer 02 · Telephony
Native CPaaS
Our own SIP trunks and carrier integrations — every call runs on infrastructure we control end to end.
Others resell Twilio or Exotel at a markup.
Layer 03 · Channel
WhatsApp Voice
End-to-end AI voice agents over WhatsApp Business calling — real voice conversations, not just chat.
Only one other player in India offers this.
