AST secures 3 billion won in investment

ASET announced on the 24th that it had raised a total of 3 billion won through a Pre-A bridge investment round in September 2025.

ASAT is a technology-based startup developing all-solid-state, composite electrolyte membrane technology that simultaneously improves fire safety and energy density.

In this Pre-A bridge investment round, Small and Medium Business Bank and Pathfinder H participated as new investors, and existing investors Ascendo Ventures and Tap Angel Partners continued their trust by making follow-on investments.

Through this investment, which involved major venture capital and financial institutions, ASAT secured the funds necessary for technology commercialization and transition to mass production.

An investment industry insider commented, “In the current conservative capital market environment, the fact that AST has attracted continuous investments in a short period of time demonstrates confidence in the company’s growth potential and strong trust in the potential of all-solid-state electrolyte technology.”

Park Seok-jeong, CEO of ASAT, said, “This Pre-A Bridge investment is a recognition of our technological prowess and growth potential,” and added, “Based on the trust of new and existing investors and the selection for government projects, we will accelerate the commercialization of all-solid-state electrolyte membranes.”

He continued, “In particular, our all-solid-state electrolyte membrane has great market expandability as it can be widely applied from inverted solid to all-solid-state batteries due to its compatibility with existing liquid electrolytes,” and emphasized, “With the addition of CTO Hyun-Seok Choo, we will smoothly push forward with our roadmap for entering the global market and large-scale mass production, and through the submission of A samples, we will begin full-scale cooperation with the world’s major battery manufacturers.”
