Tesollo, an Incheon-based maker of robotic hands, began IPO preparation in early July 2026 after closing a Series B round. Investors include POSCO Technology Investment, KB Investment and Enlight Ventures, alongside strategic backers Daesung Hi-Tech and HL Mando.
"Through our IPO, we aim to establish a corporate foundation that global customers can trust," said CEO Young-Jin Kim. The company exports to 19 countries.
The specs, and the caveat
Tesollo's DG-5F hand has 20 independently driven joints. The newer DG-5F-S weighs under 1 kg at roughly 60% of its predecessor's cost — the two variables that decide whether a hand can ride on a mobile humanoid rather than a bolted-down arm.
The more useful disclosure is the one about reliability: no manufacturer is close to a certified 10,000-hour mean time between repairs for a dexterous hand. That number is the gate between demonstration and deployment. A hand that fails every few hundred hours of contact-rich work is a consumable, and consumables have to be cheap enough to treat as such.

Why it matters
Korea's realistic position in physical AI is the component layer, and the hand is the component with the worst supply. Actuators and reducers have incumbents; multi-fingered hands with usable durability do not. A listed Korean pure-play in that gap would be the first of its kind.
It also frames the honest state of dexterity. The models are improving faster than the mechanisms they run on, and reliability — not degrees of freedom — is what decides whether a hand ships.
