Tesollo Initiates IPO Process While Developing Humanoid Hands
Tesollo Inc., a South Korean developer of robotic hands, has officially begun preparations for an initial public offering (IPO) slated for the coming year. The company also announced the completion of its Series B funding round to support global expansion.
Based in Incheon, South Korea, Tesollo specializes in manufacturing core robotic components, advanced end effectors, and systems designed to improve robot autonomy and human-robot collaboration.
“Through our IPO, we aim to establish a corporate foundation that global customers can trust and accelerate our expansion into overseas markets,” said Young-Jin Kim, CEO of Tesollo. “By strengthening our mass-production capabilities and advancing our core technology development, we will continue to grow into a global leader in the robotic hand sector.”
Existing shareholders, including POSCO Technology Investment, KB Investment, and Enlight Ventures, participated in the Series B round as follow-on investors. Strategic investors from the industrial sector, such as Daesung Hi-Tech and HL Mando, also joined the round. Tesollo said the investment reflects recognition of its technological capabilities and growth potential.
Global Reach and Product Portfolio
Founded in 2019, Tesollo is securing customers in major markets including the United States, China, and Japan. To date, the company has exported its products to 19 countries, and overseas sales have recently surpassed domestic sales, marking its transition into a global enterprise.
Tesollo demonstrated its DG-3 three-fingered gripper at AW 2026 in March. Its product line ranges from the DG-2F parallel gripper to the five-fingered DG-5F.
The company claims it developed the DG-5F-S using proprietary in-house actuators to weigh less than 1 kilogram (2.2 lbs). This model offers high precision and stability at about 60% of the cost of its predecessor, helping accelerate the commercialization of humanoid robots.
Tesollo was an exhibitor at the recent Robotics Summit & Expo in Boston and also demonstrated the DG-5F-M and DG-5F-S robotic hands at the ICRA show in Vienna, showcasing teleoperation, bin picking, in-hand manipulation, and its humanoid vision-language-action model (VLA).
The company has matured its product line with a pragmatic strategy to become a specialist in multi-jointed robotic hands for humanoids.
Focus on Reliability and Mean Time Between Repair
Humanoid manipulation remains a difficult application because the hands are nearly as complex as the rest of the humanoid body. End-of-arm tooling (EOAT) is subjected to stress and wear higher than any other component on the robot.
Mean time between repair (MTBR) and mean time to repair (MTTR) are key performance indicators for humanoid robotic grippers. Many users complain of frequent breakage and time spent fixing broken fingers and joints. According to an analysis by ENGtechnica, the structural complexity creates a disproportionate “failure density” where dozens of micro-actuators, sensors, and tendon-driven cables act as single points of failure.
Tesollo said it recognized this issue early in development. Its DG series is designed to make fingers and joints easy to repair and replace as hands fail during normal operations. The diverse use cases for humanoid hands, combined with the need for component longevity, remain challenging for every manufacturer.
Currently, no manufacturer is close to a certified 10,000-hour MTBR, and this metric is crucial for humanoid hands to survive industrial and commercial deployment.
