  • Nums AI

    Participated · Seed · Jul 2026

    Nums AI develops tabular foundation models that analyze and predict missing values in structured data (rows and columns) in a single inference step. Its TFM approach is designed to handle multiple tasks—such as demand forecasting, anomaly detection, and credit evaluation—without building separate task-specific models. The company plans to commercialize via API offerings and on-premise deployments for customers with data-export constraints, targeting sectors like manufacturing, finance, retail and commerce, and healthcare. Nums AI intends to use its recent seed funding to expand GPU infrastructure and grow its research team to accelerate model development. The company was founded by CEO Jae-min Yoo, an academic with a Google PhD Fellowship and assistant professorship background, alongside co-founders Doo-ho Lee and Min-yong Cho, who bring research and engineering experience in structured-data AI.

  • Refilled

    Participated · Series B · Mar 2026

    Refilled, run by Constant, offers scalp-care products and services that rely on an AI-based scalp scan device and more than one million accumulated data points to match users with appropriate products. The company reframes hair and scalp management as daily routine care rather than medical treatment. It has attracted strategic investors including Amorepacific and Hana Ventures prior to the Series B. With the new financing, Constant plans to further develop its scalp-care technology and expand internationally, targeting North America. The company will also invest in marketing to build brand trust as it scales.

  • Sionic AI

    Participated · Series A · Dec 2025

    Founded in 2023 and headquartered in Seoul, Sionic AI develops AI-based enterprise software tailored to the stringent security and regulatory requirements of banks and large enterprises. Its flagship Storm Platform lets customers create no-code AI agents, automatically parse unstructured data, employ high-precision retrieval-augmented generation (RAG), and govern sensitive information. By lowering technical barriers, the company aims to make advanced AI broadly accessible across industries. The fresh capital gives Sionic AI a total of ₩25 billion ($18.1 million) raised to date and positions it to deepen product capabilities and scale go-to-market efforts. Management plans to hire additional AI experts and expand geographically into Japan and Southeast Asia. Although revenue and user numbers were not disclosed, the company is still in its early commercial phase, focusing on platform enhancement and market entry. Its long-term vision is to become a foundational enterprise AI infrastructure provider throughout Asia.
