  • BEI

    Participated · Series B · Aug 2026

    BEI develops and manufactures anode-free lithium metal batteries designed for high energy density and power; its current-generation cells exceed 500 Wh/kg according to the company. Independent testing by About:Energy confirmed leading energy density and power characteristics, and a BEI-powered drone demonstrated over 30 minutes of flight at −26°C during a field demo in Finland. BEI reports more than 30 global UAV customers are evaluating or deploying its cells, which are already integrated into operational small unmanned systems. The company is commercially shipping its AFLMB cells today while advancing a roadmap targeting future cell generations with energy densities above 600 Wh/kg. With the Series B proceeds, BEI plans to scale manufacturing, run customer qualification programs, and expand commercially across Korea, the U.S., and Europe. Strategic partnerships and investor relationships aim to strengthen supply-chain resilience and support adoption in defense, robotics, and electric mobility markets.

  • Asteromorph

    Participated · Seed · May 2026

    Asteromorph develops a foundation model, Spacer, that it says combines a base LLM with deep domain knowledge and multi-step reasoning to autonomously generate research ideas and scientific hypotheses in biology and chemistry. Its flagship initiative, the "Library Project," aims to run the autonomous system at scale to uncover fundamental mechanisms of life and compile findings into a structured database. The company emphasizes autonomous hypothesis generation and end-to-end scientific workflows rather than solely assisting human researchers. Leadership includes CEO Lee Min-hyung, who entered advanced research training early, and a core team of young researchers from top Korean STEM programs. Financially, Asteromorph has raised a $31.4M seed round and previously raised approximately ₩5 billion. The company faces the challenge of validating model-generated discoveries through rigorous experimental work at scale.
