AsianFin -- Seoul-based Datumo, originally an AI data labeling company, is expanding its mission to help businesses build safer AI by providing tools and data that facilitate testing, monitoring, and improving AI models without requiring deep technical expertise.

On Monday, the startup announced it has raised $15.5 million, bringing its total funding to around $28 million. The latest round includes investments from Salesforce Ventures, KB Investment, ACVC Partners, SBI Investment, and others.

Datumo’s CEO, David Kim, a former AI researcher at Korea’s Agency for Defense Development, was motivated by the labor-intensive process of data labeling. He developed a reward-based app that enables anyone to label data in their spare time while earning money.

The concept was validated during a startup competition at KAIST (Korea Advanced Institute of Science and Technology). Kim co-founded Datumo, initially known as SelectStar, in 2018 alongside five fellow KAIST alumni.
