Centaur Labs uses a network of over 50,000 vetted experts to label multimodal health and science data for model training, evaluation, monitoring, and feedback. It operates a HIPAA-compliant platform and a mobile app, DiagnosUs, where experts compete to be top annotators to ensure high-quality labels. The company says its expert-sourced approach delivers annotation accuracy superior to typical in-house teams or outsourced generalists. Centaur Labs recently launched an on-demand AI data labeling product that enables developers to collect expert labels in less than one hour. The company intends to use the new funding to expand operations and accelerate product development. Centaur Labs provides medical data labeling across images, videos, text, and audio by crowding a vetted network of tens of thousands of medical students and professionals. The company primarily captures labels via its gamified iOS app, DiagnosUs, which assesses labeler performance, rewards top contributors, and collects multiple opinions per case. Centaur combines multiple expert opinions into consensus labels, and the platform generates more than 1 million opinions each week from users in over 140 countries. Customers and collaborators include medical AI startups like Eko Health and research institutions such as Brigham and Women’s Hospital. The new capital will be used to expand the company’s global network of labelers, accelerate product development, and hire across the organization. Centaur participated in Y Combinator and emphasizes scaling its labeling infrastructure to support broad medical AI development.
