Circuit Mind, a London startup that uses AI to design and verify circuit boards, said on Wednesday it raised $25 million in new funding, bringing its total to $33.4 million.
This funding included an $ 18.5 million Series A led by Norwest. Existing investors include Third Prime, Differential, and Blackhorn, which joined the Series A, along with new investor Lightscape VC. Dave Zilberman, a general partner at Norwest, will also join Circuit Mind's board.
According to the company, hardware teams spend more than a year building a new device. Engineers often read datasheets that run to thousands of pages, and many errors stay hidden until someone builds and tests a prototype.
"Software teams are shipping 100 times faster with AI, but electronics design hasn't changed in 40 years," said Tomide Adesanmi, co-founder and chief executive officer of Circuit Mind.
Adesanmi compared the company's goal to what AI coding tools such as Cursor and Claude Code have done for software developers.
"Electronics design is one of the most complex and consequential engineering workflows," Zilberman said.
Two applications
Circuit Mind runs two applications on its platform. The first, ACE, turns a hardware block diagram into a schematic, a bill of materials, and supporting analysis in minutes. This lets engineers receive several design options, each tuned to a priority such as cost, size, power, or supply chain. Finished designs export into the electronic computer-aided design (ECAD) software their teams already use.
The company launched the second, the Agentic Verification Engine (AVE), alongside the funding. AVE assigns a group of AI agents to review schematics against component datasheets, application notes, and each customer's design rules. Some agents check constraints such as pin tables and operating voltages, while others trace every connection and bus. The system then reviews its own findings and reports only those that hold up.
Circuit Mind built AVE mainly for schematics that engineers draw by hand in ECAD tools. Teams can request access or a demo through the company's website. The company will exhibit at Electronica 2026 in Munich from Nov. 10 to 13.
The company argues that general-purpose large language models cannot do this work alone because no one trained them on professionally designed circuits. Its platform layers AI agents over a patented, physics-based engine that tests each design decision against electrical limits.
Customers and results
Circuit Mind names Emerson, Schneider Electric and unnamed Fortune 5 companies among its customers. The company says these teams cut design time from months to weeks and reduced bill-of-materials costs by 25%.
Plans for the money
Circuit Mind plans to extend its platform across more of the design lifecycle, including design analysis, reporting, testing and firmware. The company will also hire across sales, engineering, and customer success and open a U.S. headquarters to serve North American customers.
Tomida Adesanmi serves as CEO, and Basilio Gentile, the company's chief technology officer, founded Circuit Mind in London in 2018.
