CircuitHub, a company focused on speeding up electronics production, has raised $28 million to accelerate hardware development and manufacturing. The round was led by Plural, an operator-led venture firm whose founders include Taavet Hinrikus, Sten Tamkivi, Ian Hogarth, and Khaled Helioui.
The money will fund the expansion of CircuitHub’s automated factories across the US and Europe, grow its engineering team, and extend the platform into full-service electronics manufacturing. Founded by chief executive Andrew Seddon, the company has built an automated electronics manufacturing system that turns design files into printed, production-ready circuit boards in a matter of days. Its research roots are in Cambridge, UK, with a growing team across London forming the base for a wider European footprint, and it opened its first facility in Massachusetts to stay close to early customers.
The pitch rests on a structural gap in the industry. About 95 percent of electronics projects today involve fewer than 10,000 units, yet manufacturing remains optimized almost entirely for mass production. For most hardware teams, the process still looks much as it did in the 1990s, with manual assembly, supply chain bottlenecks, and rising labor costs stretching iteration cycles into months. Much of the world’s manufacturing also sits overseas, with critical supply chains concentrated in China, a dependency increasingly exposed to geopolitical tension. The US alone has lost more than 85 percent of its share of the global PCB market to lower-cost overseas manufacturers, and both US and European governments and companies are now working to rebuild domestic capacity.
CircuitHub’s approach takes inspiration from semiconductor fabs, among the most automated systems anywhere. Engineers building self-driving cars, satellites, and similar systems can upload their designs and order circuit boards in seconds through the company’s online platform. From there, CircuitHub uses automated robotics, computer vision, and AI to assemble the designs at its first 5,000-square-foot factory, called the Grid, before shipping them to teams worldwide. With a small on-site team monitoring quality, the Grid can produce a single prototype or batches of 10,000 units across dozens of different designs at once. That compresses production from months to days and makes high-mix manufacturing, where many designs are produced in small batches, economically workable in an industry still built for mass output.
Since opening its Massachusetts facility, CircuitHub has delivered more than 2 million boards and placed over 133 million parts, serving 20,000 engineers across some of the largest and most innovative hardware teams. The company describes itself as the fastest-growing electronics manufacturer in the US. Over time, it plans to make its factories increasingly modular so new capacity can be deployed wherever it is needed, scaling on-demand manufacturing to reduce reliance on distant supply chains and strengthen domestic control over critical technologies.
