The money will go toward expanding production capacity and building out global markets.
The re-raise: The round comes just months after ZeroErr's previous financing, a sign of investor appetite as the company scales. Founded in 2016, it develops high-reliability, high-precision, standardised core robotics components for the global robotics and automation industry.
By the numbers: ZeroErr posted revenue growth of more than 100% in 2025 and expects to double again in 2026. Orders from the humanoid and embodied-intelligence robotics segment are driving roughly 65% of that growth.
Why now? The humanoid robotics sector has moved past hype into a phase where supply-chain capacity and reliability are the real bottlenecks. "Downstream customer demand has rapidly shifted from 'is there a mature product' to 'can you supply on time'," founder Jia Xiqing told 36Kr.
What's the endgame? ZeroErr aims to turn robot joints into standardised, off-the-shelf parts. Its eRob series spans multiple form factors, with the smallest module measuring 70mm in diameter and the largest allowing torque up to 1,180Nm.
The edge: The company says its integration approach cuts axial length by 44% and total weight by more than 20% versus common industry designs at equivalent load ratings. Its modular, "Lego-style" design reduces a five-degree-of-freedom arm from 30 to 40 separate parts down to seven, lowering assembly difficulty and failure rates.
What could go wrong? Scaling remains the hard part. Jia points to a gap between building one prototype and producing at volume with consistency, compounded by upstream motor and gearbox suppliers who need months to expand their own capacity.
The signal: With humanoid robotics entering small-batch production, the industry's constraint is shifting from engineering to delivery. As Jia puts it, whoever can scale capacity while holding reliability "will capture this wave" — and upstream component makers are becoming the sector's true gauge.
