Deepgram, an API platform offering voice AI capabilities like speech-to-text and text-to-speech, recently raised a $130 million round of Series C funding. The raise, led by AVP, values the company at $1.3 billion. Deepgram strives to provide the AI solutions necessary to power billions of live conversations with the likeness of human voice.
The company equips more than 1,300 organizations with autonomous voice agents designed to offer accurate speech understanding, generation, analytics and orchestration in real time. Deepgram’s AI models are customizable and can be deployed as cloud models or through self-hosted and on-premises options.
Deepgram announced its acquisition of AI-native voice platform OfOne alongside its Series C raise. OfOne serves restaurants and the quick-service drive-thru sector, and its technology will be tied into Deepgram for Restaurants. The integration will enable Deepgram to help restaurants further improve customer experience and increase order accuracy through AI assistance.
Additionally, Deepgram will invest in expanding its intellectual property, building on a portfolio that includes several U.S. patents secured in 2025 for capabilities such as hardware-efficient automatic speech recognition. Deepgram is also opening a Voice AI Collaboration Hub in San Francisco, an office space that will host live demonstrations, executive briefings, developer hackathons and other events.
