TenX Semi exits stealth with seed round led by Khosla, South Park Commons
What's the deal? TenX SemiDealroom has a profile for this one. Try Dealroom →, a Silicon Valley startup building autonomous chip-design tools, has exited stealth with a seed round co-led by South Park Commons and Khosla Ventures. The company did not disclose the amount. It had operated in stealth for about 15 months, according to newsletter Stealth Startup Spy.
What's the endgame? TenX Semi ties chip design and verification into a single loop rather than treating them separately. Its "self-verify-and-fix" technology finds bugs, narrows down their cause, and repeats the process to fix them — aiming to cut design time while raising quality.
The company says one Tier-1 customer used the tool to catch a critical bug in a production design within two weeks and demonstrated verification 30 times faster than standard industry flows. The customer was not named.
Why now? As agentic AI speeds up chip design, verification — confirming the output is actually correct — has become the new bottleneck. That step still leans on manual work, TenX Semi argues, meaning the constraint has simply shifted downstream.
Who's behind it? The three founders span semiconductors, chip design, and AI research. Chief executive officer Suk Hwan Lim previously served as corporate executive vice president at Samsung Electronics System LSIDealroom has a profile for this one. Try Dealroom → and held roles at GoogleDealroom has a profile for this one. Try Dealroom →, Apple, and HP over a 21-year career. Co-founder Subhasish Mitra, a Stanford professor, created X-Compact, a verification method that became an industry standard. The third founder, Shwetabh Verma, has worked as an Apple hardware architect and held senior roles at Broadcom and Cadence Design SystemsDealroom has a profile for this one. Try Dealroom →.
The signal: TenX Semi enters a crowded field. ChipAgents has raised $74 million to date, Cognichip pulled in a $60 million Series A backed by IntelDealroom has a profile for this one. Try Dealroom →'s chief executive, and Ricursive Intelligence — founded by researchers behind Google's AlphaChip — raised a $300 million Series A at a $4 billion valuation. Most rivals chase design speed; TenX Semi's bet is that folding verification into the same loop is where the real bottleneck, and the opportunity, now sits.
