WIRobotics raises $68M after scaling wearable robots
WIRobotics has sold more than 3,000 WIM walking-assist robots and is now funding ALLEX, its force-controlled humanoid platform.
The South Korean company said the round was led by JB Investment, with participation from InterVest, Hana Ventures, Smilegate Investment, SBVA, NH Investment & Securities, Company K Partners, GU Investment and FuturePlay. The financing follows a KRW 13 billion Series A in March 2024.
WIRobotics was founded in 2021 by Yongjae Kim and Yeonbaek Lee after earlier work in Samsung’s robotics development organisation. Its first commercial product was WIM, a wearable walking-assist robot designed to assist walking.
The Products
WIM has passed 3,000 cumulative units sold and expanded into Europe, China, Türkiye and Japan. Revenue grew from KRW 560 million in 2023 to KRW 1.3 billion in 2024 and KRW 2.79 billion (~$1.9M) in 2025, with first-quarter 2026 revenue already exceeding the company’s full-year 2024 revenue.
WIRobotics describes the platform around force sensing, compliant interaction and contact-rich movement, with whole-body responsiveness across arms, fingers and waist. The company has disclosed a 15 degree-of-freedom compliant hand, low-friction backdrivable arms and gravity compensation across the upper body.
WIRobotics plans to supply ALLEX arms, hands, body and leader systems individually or in combination for research and manipulation development.
The External Reference
When ALLEX was unveiled in 2025, WIRobotics said it had formed a strategic partnership with RLWRLD to develop the robot’s intelligence layer. WIRobotics provides the compliant humanoid hardware, while RLWRLD works on the physical-AI model layer needed to make that hardware useful for dexterous manipulation.
In May 2026, RLWRLD released RLDX-1, a dexterous manipulation model evaluated on tasks run with the ALLEX humanoid platform. RLWRLD’s technical report describes ALLEX as an upper-body humanoid with high degree-of-freedom hands, making it suitable for testing human-like functional manipulation. The company reported an 86.8 percent success rate for RLDX-1 on ALLEX tasks, compared with roughly 40 percent for Physical Intelligence’s pi0.5 and NVIDIA’s GR00T N1.6 under RLWRLD’s own evaluation setup.
RLWRLD designed the model and benchmark. WIRobotics supplied the robot platform for that external model-development work, using force sensing, compliant hands, backdrivable arms and whole-body movement.
The Round
The Series B will support wearable robotics expansion, ALLEX development, hiring and overseas growth. WIRobotics said it plans to supply a research-oriented Mobile ALLEX platform this year and is targeting initial commercialization and mass-production readiness in late 2027.
The company was also selected for the 2026 Physical AI Fellowship backed by AWS, NVIDIA and MassRobotics, giving it access to AWS credits, NVIDIA’s physical AI stack and MassRobotics’ ecosystem support.
