About David AI
David AI is the first audio data research company, bringing an R&D approach to data and developing datasets with the same rigor AI labs bring to models. Our mission is to bring AI into the real world, with audio as the gateway due to its versatility, accessibility, and human nature. As audio AI advances, high-quality training data becomes the bottleneck, which is where David AI excels.
Founded in 2024 by former Scale AI engineers and operators, David AI has quickly secured most FAANG companies and AI labs as customers. We recently raised a $50M Series B from top-tier investors including Meritech, NVIDIA, Jack Altman (Alt Capital), Amplify Partners, and First Round Capital.
Our team is sharp, humble, ambitious, and tight-knit. We are seeking the best research, engineering, product, and operations minds to join us in pushing the frontier of audio AI.
About our Machine Learning team
Our Machine Learning team operates at the intersection of cutting-edge research and production systems, converting raw audio into high-signal data for leading AI labs and enterprises. We manage the complete ML lifecycle, from researching novel speech processing algorithms to deploying models that process terabytes of audio daily.
