Cerebras Early Investor Adit Singh Joins Mayfield as Infrastructure Partner

Adit Singh has joined the venture capital firm Mayfield as an infrastructure partner. The move brings a seasoned investor with deep technical roots in chip design to a firm positioned to lead high-capital seed rounds in the AI era.

Singh will focus his investment efforts on hardware, infrastructure software, cybersecurity, and physical AI. He joins Mayfield with a track record of identifying high-growth infrastructure plays, most notably co-leading the first funding round for Cerebras during his tenure as a partner at Foundation Capital. Cerebras completed its IPO in May 2026, with valuations reported between $26.6 billion and $56.4 billion.

A Technical Approach to Venture

Singh is a trained chip designer with a background in electrical engineering, a pedigree he views as a competitive advantage in the current market. "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 said.

Before joining Mayfield, Singh's career spanned several key roles in the venture ecosystem. He co-founded Neotribe Ventures in 2017 and previously served as a partner at Cota Capital. His transition to Mayfield is the result of a long-standing professional relationship with managing partner Navin Chaddha. The two have previously served together on several startup boards, including Velaura AI and Upscale AI. Regarding the timing of the hire, Chaddha noted that the two had been talking for a long time and "this time stars aligned."

The Rise of the Mega-Seed

Singh was drawn to Mayfield by its existing semiconductor portfolio, which he described as "probably the best in the market right now." However, the attraction extends beyond the portfolio to the firm's financial firepower. With $3 billion in assets under management (AUM), Mayfield is capable of writing seed checks of up to $20 million.

This capability reflects a broader shift in the venture landscape toward "mega-seed" deals. In sectors like semiconductor design and physical AI, the capital requirements for initial prototyping and talent acquisition have skyrocketed. The ability to provide significant early-stage capital, combined with transistor-level technical expertise, allows firms like Mayfield to compete for the most ambitious infrastructure startups.

Market Implications

As AI continues to move from pure software into physical applications and specialized hardware, the demand for partners who can vet the underlying physics of a product is increasing. Singh's appointment signals Mayfield's intent to double down on the "plumbing" of the AI revolution—the chips and infrastructure that make large-scale models possible.

Industry observers will be watching to see which new hardware plays Singh backs in the coming months, particularly as the industry seeks alternatives to dominant GPU architectures and explores the next generation of physical AI integration.
