Analysis
Circuit Mind, a London-headquartered startup that uses AI to design and verify circuit boards, announced $25 million in new financing on Oct. 28, 2026, the company said.
The round includes a previously unannounced seed led by Third Prime and an $18.5 million Series A led by Norwest, bringing Circuit Mind's total funding to $33.4 million. Existing investors Third Prime, Differential and Blackhorn participated in the Series A alongside new investor Lightscape VC; Dave Zilberman, a general partner at Norwest, is joining Circuit Mind's board.
What Circuit Mind does
Circuit Mind was founded by chief executive Tomide Adesanmi and co-founder Basilio Gentile to let enterprise electronics teams design, verify and optimize circuit boards with AI agents instead of manual engineering cycles. Its flagship product, ACE (Assistant to Circuit Engineers), turns a hardware block diagram into a schematic, bill of materials and analysis. The company used this announcement to launch a second product, AVE (Agentic Verification Engine), which uses AI agents to check finished designs against component datasheets and design rules.
Circuit Mind says engineering teams at Emerson, Schneider Electric and unnamed Fortune 5 companies already use its tools, claiming reductions in design time from months to weeks and a 25% cut in bill-of-materials cost. A case study with Los Alamos National Laboratory reported a design finished in four hours that the lab says would otherwise take two weeks.
Circuit Mind's funding history
Circuit Mind's seed round was led by Third Prime; its amount and timing were undisclosed until this announcement. The Series A announced this week, led by Norwest, is the company's first formally disclosed round size, and the combined financing is funding a new US headquarters alongside Circuit Mind's existing London base.
Who invested in Circuit Mind
Norwest led the Series A, with general partner Dave Zilberman taking a board seat as part of the deal. Third Prime, which led the seed round, returned for the Series A alongside Differential and Blackhorn; Lightscape VC is the only investor named as new to this specific round.
Electronic design automation's market and competitors
The broader electronic design automation market was valued at $20.93 billion in 2026 and is projected to reach $43.07 billion by 2034, a 9.4% annual growth rate, according to Polaris Market Research data cited by Silicon Semiconductor.
Circuit Mind is not alone in applying AI to hardware design: Flux, a comparable printed-circuit-board automation startup, has raised $37 million across two rounds, including a Series B led by 8VC and a seed backed by Outsiders Fund and Bain Capital Ventures, according to SiliconAngle.
Circuit Mind's chief executive has compared the company's ambitions to what Cursor, Claude Code and Cognition have done for software engineering, arguing general-purpose large language models are not accurate or trained enough on professionally designed circuits to replace specialized tools.
What to watch
The Los Alamos case study -- a four-hour turnaround Circuit Mind says would normally take two weeks -- is the clearest external validation point in the company's pitch. How that result holds up across more customers, rather than the funding total itself, will determine whether Circuit Mind or Flux pulls ahead in a still-nascent category Pulse is tracking as part of this year's broader run of funding rounds.
