David AI is an audio data research company focused on building the data backbone for voice-based AI, enabling AI to enter the real world through voice interfaces in wearables, robots, and customer support agents. Founded in 2024, the company addresses the critical shortage of high-quality audio training data, as existing public datasets are insufficient for advanced voice models. David AI runs a full-stack data research lab, meticulously collecting and refining high-signal audio datasets with the same rigor applied to model training. In under a year, they have grown to power audio training for leading AI labs and major tech companies, achieving an eight-figure revenue run rate and supporting everything from voice agents to advanced research.
