Datumo develops tools to verify and evaluate the reliability and performance of large language models, helping prevent errors and ensure safety in regulated industries. Its platform can automatically generate test questions, build test sets, and run end-to-end evaluation and analysis of model behavior. The company also provides AI development services, including creating pretraining datasets (for example converting printed text to datasets via OCR). Datumo was founded in 2018 (originally named electStar) and is participating in a government-selected consortium to develop a domestic base AI model, where it handles AI data engineering. The company is expanding internationally into Japan and the U.S.; its strategy chief moved from Seoul to Silicon Valley to lead global expansion.
