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

This article was published on May 20, 2026 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
