The problem
Warehouses can’t hire fast enough, yet each new robot arrives dumb: integrators spend weeks hand-teaching it one task, and a facility with three robot brands runs three incompatible software stacks.
How it works
Mujin’s controller bolts onto standard industrial arms and gives them eyes and a brain — machine vision reads the merchandise, a real-time digital twin plans the optimal motion, and the arm executes picking, palletizing, and depalletizing with minimal manual input. MujinOS unifies mixed-brand fleets behind one interface, and Mujin’s own QuickBot and TruckBot handle pallet and trailer unloading.
Pain points
Integration backlogs measured in weeks per cell, dependence on scarce robotics engineers, and rising parcel volumes colliding with a shrinking warehouse workforce.
Business model
Hardware (controllers, QuickBot, TruckBot) plus MujinOS software licenses and integration services, expanding across fulfillment, machine tending, and fleet management.
Challenges
Long enterprise sales cycles, the cost of building integrator and service networks across the US and Europe, and platform competition from both robot OEMs and well-funded automation startups.
Funding
- Raised: $233M Series D first close ($133M equity led by NTT Group with Qatar Investment Authority co-lead, plus $100M debt from Japanese financial institutions); earlier an $85M Series C (Sep 2023, SBI-led) plus an $18M extension with Japan Post Capital, taking cumulative funding to $178M at that point (company announcements).
- Valuation: MISSING.
Latest — December 2025
Mujin announced the $233M Series D first close to scale MujinOS as its flagship intelligent-robotics platform — doubling down on digital-twin orchestration and expansion across European and North American engineering, service, and integrator networks, with a second close planned.
