Founded in 2018, Select Star specializes in building high-quality AI training datasets and assessing model reliability through its flagship solution, Datumo Eval. The company services more than 320 clients, spanning South Korea’s top five conglomerates and leading financial groups. Its technology enables an end-to-end pipeline—from data preprocessing and generation to reliability scoring—tailored for AI agent and AX (AI experience) use cases. Select Star plans to evolve this capability into an all-in-one platform and pursue global expansion. The firm is also a member of the SK Telecom-led consortium developing a national AI foundation model. Select Star’s growing role as an AI data partner to financial institutions was underscored by its recent selection as the top startup in Samsung Life’s C-Lab Outside program. Cumulative funding now stands at ₩43.4 billion (≈US$32 million).
