CircuitHub announced it has raised $28 million in funding to expand its automated electronics manufacturing capabilities and accelerate electronics production timelines from months to days. The funding round was led by Plural and Sten Tamkivi, bringing the company’s total funding to date to $48 million.
Founded in 2012, CircuitHub initially focused on streamlining electronics manufacturing by enabling engineers to upload EDA files, receive quotes within minutes, and order assembled boards online. Over time, the company evolved beyond simplifying the ordering process and shifted its focus toward fundamentally improving manufacturing efficiency, quality, speed, and scalability.
Today, CircuitHub operates an advanced PCBA factory powered by its proprietary Grid system, a factory-scale robotic platform designed to automate electronics assembly. The company said the Grid resembles semiconductor fabrication systems more than traditional contract manufacturing operations. CircuitHub routinely delivers one-off prototype PCBAs within two to three days while maintaining competitive pricing.
The company has shipped more than 2 million boards, placed more than 133 million parts, and served over 20,000 engineers. CircuitHub said its long-term goal is to make electronics prototyping as fast and accessible as 3D printing by continuously reducing lead times and costs.
CircuitHub also revealed that it had quietly raised approximately $20 million prior to this latest financing, primarily from angel investors within the electronics and manufacturing industries. The company noted that developing factory-scale robotics systems requires substantial upfront investment.
The new capital will support a major expansion of CircuitHub’s manufacturing capacity through 2027, including scaling operations at its Massachusetts factory and expanding into Europe. The company said its existing R&D offices in London and Cambridge in the United Kingdom provide a foundation for its European growth plans.
CircuitHub believes shifts in global electronics manufacturing dynamics have created an opportunity for domestic and regionalized automated production systems. The company pointed to the decline of the U.S. PCB manufacturing sector and the high labor costs associated with traditional high-mix electronics manufacturing services.
According to CircuitHub, approximately 90% of high-mix U.S. EMS assembly cost of goods sold is tied to labor expenses. The company said its Grid platform bypasses many of these challenges through fully automated production systems supported by remote teleoperation and increasing AI-driven automation.
CircuitHub envisions the Grid evolving into a fully self-contained supply chain ecosystem, where component suppliers and robotics manufacturers can all build products within interconnected automated manufacturing environments.
