Tokyo's Mujin Closes $233 Million Series D Led by NTT and Qatar's QIA to Scale Its MujinOS Automation Platform
Industrial-robotics software maker Mujin raised $233 million in a Series D led by NTT Group and co-led by Qatar Investment Authority, bringing total funding to $411 million as it eyes a 2030 IPO.
Overview
Mujin, a Tokyo-based developer of control software for industrial robots, has closed a $233 million Series D funding round led by Japan’s NTT Group, with Qatar Investment Authority as co-lead investor. According to Mujin, the company raised $133 million in equity and secured $100 million in debt financing from a group of leading Japanese financial institutions. The round brings Mujin’s total funding to date to $411 million.
What We Know
The equity portion was led by NTT Group, followed by Qatar Investment Authority (QIA) as co-lead, with Mitsubishi HC Capital Realty and Salesforce Ventures also participating, according to Mujin. DC Velocity reports the same structure, listing the $133 million equity tranche and $100 million in debt from Japanese financial institutions, and confirms that total funding to date stands at $411 million.
The capital is earmarked for scaling MujinOS, the company’s automation platform. DC Velocity describes MujinOS as a unified industrial automation platform that enables rapid development, deployment and replication of high-value applications including order fulfillment, palletizing, bin picking, machine tending and truck unloading. Mujin says it will use the funds to accelerate global adoption of the platform and broaden its presence by expanding regional engineering, service and support teams, according to DC Velocity.
Mujin frames the raise as validation of its software-first approach. “The strong support shown in our Series D round underscores investor confidence in MujinOS as the architecture that will power the next era of industrial automation,” said co-founder Ross Diankov, according to Mujin. Co-founder Issei Takino added: “Building on the world-class industrial automation technologies we have developed over the past 14 years, we will accelerate our global expansion through productization and strategic partnerships,” per Mujin.
The company was founded in 2011 as a spinout of the University of Tokyo, and plans to go public by 2030, according to Crypto Briefing. The same report notes that Mujin’s $233 million Series D closed on December 2, 2025, and describes MujinOS as a no-code platform designed for factory and warehouse automation.
What We Don’t Know
Mujin’s company announcement does not disclose a post-money valuation for the round, and the participating financial institutions behind the $100 million debt facility are not individually named, according to Mujin. The choice of listing venue for the planned 2030 IPO has not been confirmed in the sources reviewed here.
Analysis
Mujin’s pitch differs from the humanoid-hardware narrative that has dominated recent robotics fundraising. Rather than building robots, the company sells an operating layer intended to coordinate machines from multiple vendors across warehouse and factory tasks. The presence of NTT Group as lead investor and a sovereign-wealth co-lead in Qatar Investment Authority signals continued institutional appetite for industrial automation infrastructure, even as much of the sector’s attention has shifted toward general-purpose humanoids. With the round, Mujin joins a wave of well-capitalized automation companies positioning their software platforms as the connective tissue of increasingly automated supply chains.
