Deepgram Founding Team
Scott Stephenson, Adam Sypniewski and Noah Shutty founded Deepgram after working in physics. The business now combines speech research, infrastructure engineering and enterprise deployment.
Deepgram Company Development
An Audio-Search Problem Becomes Enterprise Speech AI
Deepgram’s founders came from physics research at the University of Michigan. Their early work on searching large volumes of recorded conversations developed into an enterprise speech-recognition company. A $12 million Series A announced in March 2020 backed that direction, followed by an initial $25 million Series B in 2021.
The Series B Closes in Two Tranches
Deepgram’s November 2022 announcement reported an additional $47 million, bringing the entire Series B to $72 million. The distinction matters: the $72 million was not another financing on top of both earlier tranches. The company linked the proceeds to speech-understanding research and engineering, extending its ambitions beyond basic transcription.
Capital Supports a Broader Voice Platform
The January 2026 Series C raised $130 million at a $1.3 billion valuation, led by AVP. Deepgram paired the financing with the OfOne acquisition and a broader platform for voice AI. In August, it announced an EDBI strategic investment as part of a Series C extension and plans for an Asia-Pacific headquarters in Singapore; the extension amount was not disclosed.
Daily and Pipecat Extend the Infrastructure Stack
In October 2026, Deepgram announced that it was acquiring Daily, the real-time communications company behind Pipecat. The deal brings communications infrastructure and an open-source voice-agent framework alongside Deepgram’s speech models. The announced direction is a platform in which developers can choose models while connecting the transport, conversation context and agent runtime needed for production voice applications.
