- Adit Singh joined Mayfield as an infrastructure partner on Thursday, where he will invest in hardware, infrastructure software, cybersecurity, and physical AI.
- Singh helped source and co-lead Cerebras's first funding round while a partner at Foundation Capital; Foundation ended up holding roughly a 7% stake, making it the third-largest shareholder in the chipmaker, which now trades at a ~$50 billion valuation after its May IPO.
- Singh called Mayfield's semiconductor portfolio "probably the best in the market right now," pointing to Upscale AI (recently valued at $2 billion) and Lumilens (which raised $700 million at a $5.5 billion valuation).
- Singh, a chip designer by training, co-founded Neotribe Ventures in 2017 after leaving Foundation, spent four years leading it, then moved to early-stage firm Cota Capital before landing at Mayfield.
- Singh cited the ballooning size of seed infrastructure deals as a key reason for the move, noting that Mayfield's $3 billion in assets under management lets it write seed checks of up to $20 million — well beyond what smaller funds can match.
- Navin Chaddha, Mayfield's managing partner, said he and Singh have known each other for 15 years and sit on three startup boards together, including Upscale AI and Velaura AI, but that it still took time to "convince him to join."
Why it matters: Mayfield just added a chip-design-trained investor with a proven early call on Cerebras (now ~$50B) at a moment when seed infrastructure rounds have grown large enough to price out smaller funds; Singh's $20M-check capacity and existing board overlap with Chaddha on Upscale AI and Velaura AI signal the firm is doubling down on semiconductors and AI infrastructure.
