Exclusive: Anvil Robotics raises $5.5M to build 'Legos for robots' platform for physical AI teams. April 2, 2026 Anvil Robotics, an eight-month-old startup that aims to be the "Legos for robots," has raised $5.5 million in a seed funding round, it tells Crunchbase News exclusively. Matter Venture Partners and Humba Ventures led the raise, which included participation from DNX Ventures, Superhuman founder Vivek Sodera, Spacecadet Ventures and Position Ventures. Anvil had previously raised $1 million in pre-seed capital from Matter in 2025. The San Francisco-based startup builds custom robots for businesses and describes itself as a hardware, software and manufacturing platform. Before starting Anvil Robotics last July, Mike Xia, CEO, and CTO Vijay Pradeep, spent six months talking to a variety of businesses. They concluded that physical AI teams in companies, big and small, were spending over six months piecing together various robot arms, cameras and open-source libraries "just to get a glued-together prototype." "This isn't a problem if you're Tesla, or have nine-figure R&D budgets, and you custom design and build everything, including hardware and software," Xia told Crunchbase News in an interview. "But for many companies, even well-funded teams, standing up a robotic system with all the sensors and tools and controls you need is a huge challenge that costs you both time and money." So the pair started Anvil to fill that gap. "We support physical AI teams who don't have $100 million, to make this industry much more accessible," Xia said. Customers can go on Anvil's site and "essentially build out what they want," he added, using either prebuilt kits or customization. "They are very much like Legos," Xia said. Anvil then ships the robots within 1 to 2 days via 2-day air freight. The company is able to do so because it has a significant presence in Taiwan, and is its own manufacturer, he said. (But more on that later.) Its robots are about the size of a middle-school-aged child, but big enough to do basic dextrous tasks. Anvil's robots typically cost $5,000 to $10,000, but its least expensive model is just $1,900. "I think the pricing is going down to a point where researchers and individuals are able to afford this," Xia said. "I think it's going to make a really big difference with the community and we'll see a lot more activity in people building physical AI applications." Anvil started shipping robots in September and has so far delivered over 100 of them to customers globally. Open-platform approach. Anvil competes with the likes of Universal Robots and Unitree Robotics but claims that it's different from other startups in the space in a couple of ways. "Most are basically building toys for rich people," Xia said. Anvil's model stands out, he believes, because it's an open platform, meaning that all of its robot designs are open-sourced. Most other startups, according to Xia, sell a proprietary design that gets customers "locked in hardware and software." "If you work with Anvil, you're not locked into a single vendor, plus you have large communities behind you," he said. Also, as mentioned above, Anvil is an actual manufacturer, and it "controls the whole stack." "We don't outsource - we do this hard part ourselves," he told Crunchbase News. "We buy each part and operate our own factory, which our customers can leverage." Further, Anvil customers can choose where their components come from and how many to build. Historically, if a U.S. company has wanted to deploy a robot, it's largely been dependent on hardware built in China. "If a business wants 10 robots made with Taiwanese or Japanese parts, we can do it," Xia said. "I believe many companies will become more aware of supply chain risk and need this. Many robots today are made in China, and we're not exactly on great terms [with the country]. Business growth. Anvil won't disclose hard revenue figures, but Xia noted that it has reached seven figures and that it has over 50 customers. That revenue mostly comes from hardware today, but the company plans to release more software, data tools and services, which should diversify its revenue base. Its customers are a varied bunch, with some "exciting" ones such as giant tech companies under NDA. Those they can talk about are a small chocolate factory based in Portland, Oregon; Nvidia's GEAR lab, which is doing the humanoid research behind GR00T; and Path Robotics, which has raised more than $300 million to automate welding and industrial tasks. So far, all of its customers have been inbound, according to Xia. "It's all been word-of-mouth, and a lot of it is community-driven," said Xia, who added that he previously co-founded another startup called Lumina Industries and was formerly chief product officer at Voltage Park. A 'robotics foundry' Haomiao Huang, founding partner at Matter, told Crunchbase News via email that his firm has been investing "at the forefront" of physical AI "for some time." "It quickly became clear that innovation on the hardware - the motors, actuators, sensors, systems, etc. - hasn't kept pace with the rapid improvement in AI. They are still stuck in the same paradigms that powered the industrial robotics of decades past." In his view, AI robots today are like "incredible brains trapped in weak, incapable bodies." That's where Anvil comes in. His firm incubated the startup to create a robotics foundry that could "move many companies forward." "Behind great generations of products are foundational platform enablers," Huang said, "and we founded Anvil to be to physical AI what AWS (Amazon Web Services) has been to SaaS and what TSMC (Taiwan Semiconductor Manufacturing Co.) has been to chips." The hard part of hardware is less about creating a great robot once, and more about making many great robots "over and over again," Huang added. Anvil's founders, he said, will be able to produce and iterate on hardware at "software-like speeds" and then deliver it at scale in production. Added Huang: "This is something unmatched." Overall, robotics startup funding hit a record high last year, per Crunchbase data. Startups in the sector raised nearly $14 billion in funding in 2025, up from $8.2 billion in 2024, even topping the $13.1 billion raised in the peak venture funding year of 2021.

Anvil Robotics, a physical AI infrastructure startup, has raised $6.5 million (approximately TWD 208 million) in seed funding led by Silicon Valley hard-tech venture capital firm Matter Venture Partners. The company was founded in July 2025 and operates with a dual-core model connecting Silicon Valley's AI innovation capabilities with Taiwan's manufacturing advantages. Within six months of establishment, Anvil Robotics has shipped over 100 robotic systems to customers including Nvidia, Stanford University, Georgia Institute of Technology, Path Robotics, Co.bot and Flexion AI. Applications span AI research, robotics development and real-world deployment. The funding will accelerate development of the company's physical AI infrastructure platform, which aims to bridge the gap between rapidly advancing AI models and hardware systems including sensors, actuators, power and control systems.
