Circuit Mind, a London company whose AI software designs and checks electronic circuit boards, has raised an $18.5m Series A led by Norwest. Existing investors Third Prime, Differential and Blackhorn took part, and Lightscape VC joined as a new investor. The company announced the round on 28 October 2026.
Circuit Mind also disclosed a previously unannounced seed round led by Third Prime. Together the two rounds total $25m of new financing, and the company says it has now raised $33.4m in all. The size and date of the seed round were not given, and the valuation was not disclosed.
Dave Zilberman, a general partner at Norwest, will join Circuit Mind's board.

What Circuit Mind does
Designing a printed circuit board means choosing hundreds of components from millions of options, reading datasheets that can run to thousands of pages, running simulations and drawing schematics. Errors often surface only when a prototype is built and tested, which can add months to a project.
Circuit Mind combines AI agents with what it calls a patented, physics-based decision engine, machine-readable models of electronic components and each customer's own rules, such as approved manufacturers and preferred parts. It connects to the electronic design software, libraries and product lifecycle tools that engineering teams already use.
Its first application, ACE, turns a hardware block diagram into a schematic, a bill of materials and supporting analysis in minutes, with design options tuned for cost, size, power or parts availability. A second application, AVE, launched alongside the funding. It uses AI agents to check designs against component datasheets and a company's design rules before a prototype is made.
Customers and results
Circuit Mind says engineering teams at Emerson, Schneider Electric and companies in the Fortune 5 use its platform, and that customers have cut bill-of-materials costs by 25%. Daniel Gheno, chief technology officer for energy management at Schneider Electric, said early evaluations pointed to more than 90% less effort spent exploring electronic architectures.
The company cites a case study in which engineers at Los Alamos National Laboratory finished a design in about four hours. The press release compares that with two weeks of work; SiliconANGLE, citing the lab's report, put the manual estimate at 60 to 80 hours.
According to SiliconANGLE, chief executive Tomide Adesanmi founded the company in London in 2018 with chief technology officer Basilio Gentile.
What the money is for
Circuit Mind will use the funding to extend its platform across more of the electronics design process, grow its sales, engineering and customer success teams and set up a US headquarters to serve North American customers. SiliconANGLE reported that the next stages include testing and firmware.
Adesanmi compared the company's goal to what AI coding tools such as Cursor and Claude Code have done for software engineering.
