What is Deepgram?

Deepgram is a voice AI company that builds the real-time speech APIs behind a large share of the emerging "voice AI economy." Its platform spans speech-to-text (STT) transcription, text-to-speech (TTS) synthesis, and full speech-to-speech (STS) capabilities, used by developers and enterprises to power voice agents, call-center analytics, meeting transcription, and real-time human-to-machine interaction. Deepgram was founded in 2015 by three former University of Michigan physicists: Scott Stephenson (CEO), Adam Sypniewski (CTO), and Noah Shutty. The founding insight came from Stephenson's background in particle physics and dark-matter detection, applying deep-learning techniques to raw audio rather than relying on legacy speech-recognition stacks. The company went through Y Combinator and has raised approximately $246M in total. In January 2026 it raised a $130M Series C at a $1.3B valuation, led by AVP, making it one of the newest unicorns in voice AI. Deepgram is headquartered in San Francisco with roughly 326 employees and a remote-friendly workforce. Its core differentiators are speed (real-time, low-latency inference), accuracy on messy real-world audio, and a developer-first API model that competes with the speech offerings of the large cloud providers and newer voice-AI startups.

Mission & values

Power the voice AI economy by giving every developer fast, accurate, and affordable speech understanding and generation, so machines can listen and speak as naturally as people do.

Qualifications

Deepgram hires across engineering (machine learning, speech and audio, NLP, distributed systems, real-time inference infrastructure, backend, frontend, security, SRE), applied AI research, product, design, developer relations, sales, sales engineering, customer success, marketing, and G&A. Application flow lives at deepgram.com/careers. Machine-learning, speech, and real-time-systems roles are the most active given the product runs low-latency inference over live audio at scale. The company is remote-friendly with a San Francisco hub; many US engineering and GTM roles are fully remote, while some leadership and specialized research roles prefer Bay Area proximity. Candidates with production experience in speech recognition, audio ML, model deployment, or real-time streaming systems are strongly prioritized.

Frequently asked questions

What does Deepgram do?
Deepgram builds real-time voice AI APIs: speech-to-text transcription, text-to-speech synthesis, and speech-to-speech. Developers and enterprises use it to power voice agents, call analytics, transcription, and live human-to-machine interaction.
Who founded Deepgram?
Scott Stephenson (CEO), Adam Sypniewski (CTO), and Noah Shutty in 2015, all former University of Michigan physicists. Stephenson's dark-matter-detection background shaped the deep-learning-first approach to audio. The company went through Y Combinator.
How much has Deepgram raised?
Approximately $246M total. The January 2026 Series C was $130M at a $1.3B valuation, led by AVP, making Deepgram a voice-AI unicorn.
Is Deepgram remote-friendly?
Yes. It runs a remote-friendly model with a San Francisco hub. Many US engineering and GTM roles are fully remote, though some leadership and research roles prefer Bay Area proximity.
What engineers does Deepgram hire?
Mostly machine-learning, speech and audio, and real-time-systems engineers, since the product runs low-latency inference over live audio. Production experience with speech recognition, audio ML, or real-time streaming is strongly prioritized.
How is Deepgram different from cloud-provider speech APIs?
Deepgram competes on speed (real-time, low-latency), accuracy on messy real-world audio, and a developer-first API and pricing model, versus the broader but heavier speech offerings bundled into the large cloud platforms.
