David AI is the first audio data research company. We bring an R&D approach to data–developing datasets with the same rigor AI labs bring to models.

Our mission is to bring AI into the real world, and we believe audio is the gateway. Speech is versatile, accessible, and human—it fits naturally into everyday life. To unlock the full potential of AI, models need more—and better—audio data. That’s where David AI comes in.

David AI was founded in 2024 by a team of former Scale AI engineers and operators. In less than a year, we’ve brought on most FAANG companies and AI labs as customers. We recently raised a $25M Series A from Tier 1 investors like Jack Altman (Alt Capital), Amplify Partners, First Round Capital, Y Combinator, and more.

Our team is sharp, humble, ambitious, and tight-knit–we love spending time together. We’re looking for the best research, engineering, product and operations minds to join us on our mission to revolutionize audio AI.
