About
Deepgram is an enterprise voice AI platform that provides APIs for speech-to-text, text-to-speech, voice agents, and audio intelligence. It is designed for developers, product teams, and enterprises that need to build real-time or batch voice experiences with cloud or self-hosted deployment options.

Free Tier Value
Deepgram’s startup program is a free-credit offer, not an always-free tier: the page states approved startups can receive up to $100,000 in credits over 12 months, deposited automatically after acceptance. Per the free_credit rule, FTV is credit_amount/3, so $100,000 maps to an estimated $33,333 per month of value. The program includes access to STT, TTS, and Voice Agent APIs, so feature parity is effectively 100% for the credited product surface.
What's included in the free tier
- Up to $100,000 in Deepgram credits over 12 months for approved startups.
- Access to Deepgram's STT, TTS, and Voice Agent APIs through program credits.
