David AI has secured $50 million in Series B funding to expand its audio data research operations. The round was led by Meritech, with participation from NVIDIA, Alt Capital, First Round Capital, Amplify Partners, and Y Combinator.

The company positions itself as the world’s first audio data research lab, focused on creating the datasets and evaluations needed to train next-generation audio AI models. David AI currently works with several Mag7 companies and most of the leading AI labs developing audio capabilities.

Addressing Audio AI’s Data Bottleneck

Audio interfaces represent a major opportunity for AI to reach billions of users through real-world applications. From humanoid robots to wearables and personal assistants, these systems rely on audio as their primary interface. But current audio AI development faces a significant constraint: access to sufficient training data.

“Audio is the frontend interface for real-world AI,” the company noted in its announcement.

The challenge goes beyond simply collecting more data. Speech evaluation is subjective and highly contextual—what makes a good conversation depends entirely on the setting. A customer support interaction requires different qualities than a casual chat with an AI companion. Audio also carries multiple dimensions that text doesn’t: emotion, tone, pace, accent, and environmental factors all matter. Multilinguality adds further complexity, as audio can’t be translated as easily as text, and regional accents create additional variables.

Taking a Research-Driven Approach to Dataset Development

David AI has structured itself as a research lab rather than a traditional data company. The team designs, tests, and collects audio datasets with the same rigor that its customers apply to model development.

The company doesn’t just focus on data quality in isolation. Instead, it examines how specific datasets actually impact model performance, allowing it to create training materials that address the real bottlenecks AI labs encounter.

This approach has helped the company establish relationships with major players in AI development. Its customers are working at the frontier of audio AI, where model progress is often limited by available training data rather than algorithmic improvements.

About David AI

David AI was founded to solve the data infrastructure problem holding back audio AI. The company operates as an audio data research lab, creating datasets that capture the full complexity of human speech across different contexts, languages, and use cases.

The funding will allow David AI to scale its operations and better serve its growing customer base. As audio interfaces become more prevalent in consumer and enterprise applications, the company aims to provide the foundational data layer that makes sophisticated audio AI possible.

Investor Background and Funding History

The Series B round brings together a mix of enterprise-focused and AI-specialized investors. Meritech, which led the round, focuses on growth-stage technology companies. NVIDIA’s participation reflects the chip maker’s broader interest in AI infrastructure across multiple modalities.

Existing investors Alt Capital, First Round Capital, Amplify Partners, and Y Combinator all participated in the new round, demonstrating continued confidence in David AI’s approach to solving audio data challenges.
