Protege

Protege is an AI infrastructure company providing a trusted platform for the secure exchange of real-world, AI-ready data between data holders and AI model builders. The platform streamlines access to private and proprietary data across domains including healthcare, video, audio and speech, spatial and physical intelligence, and other areas. For model builders, Protege offers data tailored to every stage of the AI lifecycle: pre-training (massive, diverse real-world datasets), post-training (narrower datasets for supervised training and human feedback), fine-tuning (curated datasets for domain-specific use cases), and evaluation and benchmarks (uncontaminated data to test models in real-world scenarios). For data providers, Protege enables monetization of existing data assets while maintaining clear rights protections and provenance. The platform has seen rapid adoption across healthcare, media, audio, motion capture, and more, with customers including Siemens Healthineers. Founded in 2024 and headquartered in New York City, Protege has raised approximately $65 million in Series A funding. Investors include Andreessen Horowitz (a16z), CRV, SV Angel, Bloomberg Beta, Liquid 2 Ventures, Flex Capital, Footwork, and Shaper Capital. The company has approximately 89 employees.
