ChipAgents, a Santa Clara, California startup building autonomous AI agents for semiconductor design, added $60 mn to its Series A round. The extension brings the round to $134 mn, with Micron and MediaTek returning as both investors and customers.
The company has raised capital three times in 9 months. It’s another tranche in a rapid funding cycle, and the timing says plenty about investor appetite for AI tools aimed at chip engineering.
ChipAgents closed a $21 mn Series A in October 2025, led by Bessemer Venture Partners, which brought cumulative funding to $24 mn. In February 2026, Matter Venture Partners led a $50 mn Series A1, lifting total funding to $74 mn.
The new $60 mn A2 round takes cumulative funding to $134 mn and adds B Capital to an investor group that includes Bessemer, Micron, MediaTek, Ericsson and ScOp.
William Wang, a UC Santa Barbara professor who previously worked on Amazon Q at AWS, founded ChipAgents in 2024. The company builds autonomous AI agents that work inside an engineer’s code editor.
These agents plan and execute chip design and verification tasks, turning specifications into production-ready Verilog and SystemVerilog instead of only suggesting code like a copilot.
An engineer, for instance, puts a natural-language specification or PDF into the platform and gets synthesizable RTL and testbenches without manually writing every verification step. Less handwork, fewer design gaps, faster movement from specification to chip-ready code.
Wang said semiconductor companies face rising architectural complexity and tighter delivery schedules at the same time. He said ChipAgents wants to move the sector past AI assistants and toward autonomous agents that perform real engineering work, with productivity gains, shorter time-to-market and lower design-flaw risk.
ChipAgents says it now works with more than 120 semiconductor companies, up from 80 in February and 50 last October. That customer count shows steady adoption. The ARR growth claim needs a closer read.
The company reported 6x ARR growth in the first half of 2026. That’s still fast. It also marks a sharp slowdown from the 140x year-over-year ARR growth it cited with the A1 round five months earlier, and from the 50x year-over-year growth it reported at the original Series A close. Larger revenue bases make growth multiples shrink. Still, a drop from 140x to 6x isn’t something to wave through without scrutiny.
Daisy Cai, general partner at B Capital, said ChipAgents has paired AI research with commercial execution and moved the platform into customer production environments.
Micron investment director Henry Huang said semiconductor engineering teams face pressure to deliver more advanced designs in less time. He said ChipAgents helps automate design and verification work, shorten development timelines and raise engineering productivity.
ChipAgents is growing inside a market moving fast toward consolidation. Cadence acquired rival ChipStack and folded it into ChipStack AI Super Agent, built on Cadence tools including Verisium and Cerebrus.
ChipAgents is positioning itself as an independent AI layer that semiconductor companies adopt without locking themselves into one incumbent toolchain. That pitch gets harder as EDA giants build similar features into products customers already use.
ChipAgents says it will use the new funding to scale customer deployments, expand its engineering and go-to-market teams and continue developing its AI-native chip design platform.
