Why This Matters
Singh's move signals growing VC competition for semiconductor and infrastructure deals as AI chip valuations surge.
Adit Singh, who co-led the first funding round into Cerebras at Foundation Capital, has joined 57-year-old VC firm Mayfield as an infrastructure partner. He will focus on hardware, infrastructure software, cybersecurity, and physical AI. Cerebras IPO'd in May 2026 at a valuation of nearly $50 billion.
Adit Singh, formerly a partner at Foundation Capital, helped source and co-lead Cerebras's first funding round roughly a decade ago. By the time Cerebras held its IPO in May 2026, Foundation Capital held approximately a 7% stake — making it the third-largest shareholder in the company, which now trades at a valuation of nearly $50 billion.
Singh has now joined Mayfield as an infrastructure partner, where he will invest in hardware, infrastructure software, cybersecurity, and physical AI. He cited Mayfield's semiconductor portfolio as a key draw, pointing to portfolio companies including Upscale AI (recently valued at $2 billion) and Lumilens (which raised $700 million at a $5.5 billion valuation).
"I'm a chip designer by training. My secret sauce is being able to look at any workload and see how it works from the application all the way down to the transistor," Singh told TechCrunch.
Singh also noted that ballooning seed deal sizes influenced his decision: Mayfield's $3 billion in assets under management allows it to write seed checks of up to $20 million, a scale smaller funds struggle to match.
Prior to Mayfield, Singh co-founded Neotribe Ventures in 2017 and later joined Cota Capital. Mayfield managing partner Navin Chaddha said the two have known each other for 15 years and have shared board seats at three startups, including Upscale AI and unicorn Velaura AI.
