SelectStar, a Korean startup specializing in AI data and reliability evaluation, has raised an additional $3.8 million (5.5 billion KRW) in Series B extension funding, closing its total Series B round at $17.7 million (26 billion KRW). With this raise, the company’s cumulative funding reaches approximately $29.6 million (43.4 billion KRW).

New investors Samsung Venture Investment, Mirae Asset Venture Investment, and Flux Ventures joined the extension round. Samsung Venture Investment participated through the Samsung Life Insurance strategic investment fund, positioning for synergies with Samsung Life’s AX strategy initiatives including AI agent deployment.

The investment builds on proven results. SelectStar was recently named top startup at Samsung Financial C-Lab Outside for its finance-specialized AI data pipeline and reliability evaluation solution, demonstrating its foundational value for the AI Agent era. This successful pilot collaboration with Samsung Life has now translated into strategic investment, setting the stage for expanded cooperation in financial AI verification solutions.

SelectStar initially raised $14 million (20.5 billion KRW) in Series B last August from investors including KB Investment, Shinhan Venture Investment, and Salesforce. The extension’s heavy participation from financial sector VCs reinforces SelectStar’s position as a core AI partner for Korea’s leading financial institutions.

“SelectStar’s data design and reliability evaluation technology will be crucial to Samsung Life’s AX innovation initiatives,” said a Samsung Life representative who led the collaboration. “Following this investment, we expect strong strategic synergies between Samsung Life and SelectStar.”

The funding will support SelectStar’s expansion into an all-in-one platform covering AI data preprocessing, generation, and reliability evaluation, while accelerating international growth.

“This Series B extension validates broad recognition of our AI data and reliability evaluation capabilities, particularly within the financial sector,” said Seyeop Kim, CEO of SelectStar. “We’ll continue building AX-optimized data pipelines and quality-stability evaluation platforms across domestic financial institutions and diverse industries.”

Founded in 2018, SelectStar delivers AI training data construction and AI reliability verification through its Datumo Eval solution, currently serving over 320 clients including Korea’s top 5 conglomerates and top 5 financial groups. The company also participates in the “Independent AI Foundation Model Development Project” as part of the SK Telecom consortium, contributing to Korea’s national AI development efforts.
