Best Deep Tech Companies in South Korea
The 169 best Deep Tech companies in South Korea in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: security platform inc..
South Korea's deep tech field doesn't sit still, and this directory ranks 169 companies building in it, ordered by disclosed equity funding and recent momentum. Total disclosed funding across the cohort sits at $3M, with Security Platform Inc. accounting for the bulk of that at $3M, and Aply registering $24,540. No unicorns yet, but the funding concentration tells you something about where conviction is actually landing.
The hot themes right now are EV powertrain advancements, next-generation EV platforms, and battery technology, and coverage of this space is visibly rising quarter over quarter. I'd note that the broader deep tech attention isn't unique to Korea: India's push to get deep tech startups on a global stage and Bluehill VC's moves into deep tech investment both signal that capital is actively hunting for the next cluster. So what does that mean for you? It means the 169 companies in this directory are competing in a sector where global investor attention is real, early funding is thin, and whoever scales EV drive system innovation fastest has serious room to run.
