CircuitHub raises $28M from Plural to scale automated PCB manufacturing across US and Europe

CircuitHub takes $28m from Plural to make PCBs the way clouds make compute

The Cambridge-rooted, Massachusetts-based automated electronics factory has delivered more than two million boards across 20,000 engineers. Plural's bet is on the trillion-dollar reshoring tailwind behind it. CircuitHub, the automated-electronics-manufacturing company founded by Andrew Seddon, has raised $28m in funding led by Plural. The round is the largest CircuitHub has disclosed in its 15-year history, and it will fund expansion of the company's automated PCB factories across Europe and the United States, alongside continued engineering-team build-out and a move into full-service electronics manufacturing. The pitch CircuitHub is selling is the cloud-economics analogy applied to circuit boards. The company's first 5,000-square-foot 'Grid' facility in Massachusetts takes uploaded design files, runs them through robotic assembly lines supervised by computer vision and AI quality control, and ships finished PCBs to customers in days rather than the months that a conventional contract manufacturer typically quotes. A single Grid can produce a one-off prototype or batches of 10,000 units across multiple designs simultaneously, which on the company's own framing makes high-mix manufacturing economically viable for the first time. Andrew Seddon's framing for the round was the operational pitch in a sentence. 'Hardware companies face a tough choice: either spin up their own vertically integrated manufacturing from scratch, or rely on a legacy Western supply chain that's been decaying for years,' he said in the statement. 'CircuitHub is the alternative: providing remote access to a cutting-edge factory through your browser or your AI agent. Just as software companies share cloud compute, hardware companies can now share our Grid.' The analogy is the one venture-side hardware investors have been waiting a decade to land in a concrete product. CircuitHub's track record gives the analogy its credibility. The company has delivered more than two million boards, placed over 133 million parts, and serves around 20,000 engineers across robotics, satellite, automotive-autonomy, defence and energy customers. 'Physical AI', the industry shorthand for embodied-AI hardware, is structurally bottlenecked at the PCB-and-assembly layer in a way that the model-and-software layer is not. The market arithmetic Plural is underwriting is the part worth flagging. Around 95% of electronics projects involve fewer than 10,000 units, on the wider industry data CircuitHub's release cites, yet the global electronics-manufacturing-services industry remains optimised for mass production at order volumes orders of magnitude larger. The US has lost more than 85% of its share of the global PCB market to lower-cost overseas manufacturers, predominantly in China. The category is on track to clear $1tn in size on Global Market Insights' forecast, and the long-tail of small-batch custom production has been the underserved segment of that market for most of the past decade. The reshoring framing is what Plural's investment thesis runs on. Plural partner Sten Tamkivi said what CircuitHub is doing is fundamental. Andrew and the world-class CircuitHub team are changing the unit economics of the entire industry.' Tamkivi's framing of resilience and sovereignty alongside the unit-economics argument distinguishes the Plural pitch from the standard hardware-platform thesis: European and US-controlled hardware manufacturing is now a strategic asset rather than a commodity-supply category. The wider European reshoring track is accelerating. PaperShell's €40.3m EU Innovation Fund grant earlier this year covered a copper-clad-laminate-and-PCB facility; the EU's €700m NanoIC pilot line sits at a different layer of the same supply-chain stack; Analog Devices' $1.5bn deal for Empower Semiconductor was the power-management version. CircuitHub's round is the assembly-and-fulfilment-layer version, calibrated against the small-batch end of the market the other names are not optimised for. CircuitHub was founded in 2011 by Seddon, Rehno Lindeque and Jon Friedman; R&D remains in Cambridge, UK, with commercial operations anchored at the Massachusetts Grid for proximity to early customers. The company went through Y Combinator in 2012. A planned European Grid would make CircuitHub the first dual-Atlantic automated-PCB platform at this scale. Post-money valuation, run-rate revenue and the European Grid timeline were not disclosed.

CircuitHub raises $28M to scale electronics production in days rather than months - SiliconANGLE

CircuitHub raises $28M to scale electronics production in days rather than months CircuitHub Inc., a company building automated manufacturing and assembly systems for electronics hardware at scale that supports industries such as self-driving cars and satellites, today announced it raised $28M led by Plural. Andrew Seddon, CircuitHub's chief executive, founded the company on the premise that the electronics manufacturing market could be disrupted by the same hardware innovations that led to its creation: automation. He led the groundbreaking of the company's first facility inspired by semiconductor fabs in Massachusetts, where robotics and artificial intelligence cut, prime and assemble printed circuit boards. The factory, known colloquially as the Grid, sits in a 5,000-square-foot space and uses computer vision and AI to build electronics and ship them to teams around the world. By automating large parts of the manufacturing process, the Grid can produce and prototype a single prototype or up to 10,000 units across dozens of different designs simultaneously. It allows the company to cut production time from weeks to days and makes mass production in smaller quantities economically viable. The ubiquity of the circuit board Printed circuit boards, or PCBs, are everywhere. When many people think of "electronics," they often picture a PCB: a green fiberglass square with gold lines painted on it and a few bulbous components sticking off it. Break open a keyboard or a mouse -- or even a smartphone -- and there will be a PCB holding its guts together. The buttons and plastic molding are a shiny shell designed to protect the insides, give it structure and make it functional. According to CircuitHub, most electronics projects involve fewer than 10,000 units. However, the industry is still geared towards mass production - this burden means that innovating around PCBs can become extremely costly, especially in niche markets where the most focused or critical designs aren't mass produced. "Today, hardware companies face a tough choice: either spin up their own vertically integrated manufacturing from scratch, or rely on a legacy Western supply chain that's been decaying for years," said Seddon. "CircuitHub is the alternative: providing remote access to a cutting-edge factory through your browser or your AI agent." The Asia-Pacific region, and China in particular, holds the lion's share of manufacturing capability for PCBs and electronics. According to Grand View Research, Asia-Pacific represented almost 45% of the market and CircuitHub added that the United States has lost most of its capability to the lower-cost markets overseas. In response to recent supply chain fragility and macroeconomic shifts, the U.S. and European governments and companies have pushed to rebuild domestic manufacturing capabilities. The advent of generative AI has also made it easier than ever before to design and iterate on circuit board prototype designs. Getting them to market becomes a bottleneck when manufacturing isn't print-on-demand, or necessity means building a market first with hundreds of thousands of customers (or more) to buy into the first version before iterating onto the next design. This requires vast sums of capital and pushes out small startups from taking advantage of designing and innovating hardware at software speed, something AI agents promised to bring to the industry. After all, numerous startups have already entered the industry, giving hardware engineers AI tools to automate the development and design of PCBs, including Celus GmbH and Flux. With its manufacturing facility capable of rolling out multiple designs at once, efficiently at lower volume based on AI designs, CircuitHub said it's aiming directly at shoring up this gap in the industry. The potential customer base is already present and growing. The company said the new funding will accelerate the expansion of the company's automated factories across Europe and the U.S. It also intends to take the "Grid" model and make the original AI-led manufacturing and assembly capability more modular so that it can handle increasing capacity wherever it is deployed. Since launching its first production facility, CircuitHub says it has delivered over 2 million boards and placed over 133 million parts for more than 20,000 engineers across some of the world's biggest hardware teams.
