Profile

Tesollo makes multi-finger robot hands and grippers under the Delto Gripper name, from a 3-DoF vacuum gripper up to the five-finger, 20-DoF DG-5F humanoid hand. Kim Young-Jin, a former researcher at the Korea Institute of Industrial Technology (KITECH), founded it in 2019, and it began full-scale commercialization of its multi-joint grippers in 2022. The company describes a direct-drive design in which every joint is a standardized module with its own actuator, shared across the product line. It reports that cumulative sales of hands and grippers will pass 1,000 units by the end of 2026, that it has supplied customers in more than 20 countries, and that overseas sales exceeded domestic sales in 2025. The company describes its Korean customers as including the advanced-technology research units of Samsung Electronics, LG Electronics, Hyundai Motor, Doosan and HD Hyundai Robotics. It raised a KRW 6B (about $4.5M) Series A in June 2025, with Samsung Venture Investment and POSCO Technology Investment among the new investors. In June 2026 it announced a Series B at an undisclosed amount, with HL Mando and Daesung Hi-Tech as new strategic investors, and said it has appointed KB Securities as lead underwriter for a technology-special IPO targeted after 2027. NTIS lists Tesollo as lead organisation of a trade-ministry robot-industry project to develop a 25-DOF on-device AI robot hand and precision manipulation and assembly control, with a one-year FY2026 government share (not a multi-year total) of KRW 985M (about $730,000). The company describes the same project as running from August 2026 to December 2029 with a total R&D budget of about KRW 5.2B (about $3.9M), including KRW 4B (about $3M) in government funding, with Iron Device, Hanyang University and the Korea Institute of Robotics & Technology Convergence as research partners and a dual-arm humanoid upper body as the later test platform.

Notes HQ is the head office on the company's location page: 26th floor, Posco Tower Songdo, 165 Convensia-daero, Yeonsu-gu, Incheon; the pin is the building as geocoded by OpenStreetMap. Research center and factory are in Gwangmyeong, Gyeonggi-do. The Series B amount is undisclosed, so the funding total is a floor from June 2025. NTIS targets TRL 6 for the hand project while the company's release states TRL 7 or higher. The company's own pages do not name co-founders; Kim Young-Jin is named as founder.
