Adit Singh joins Mayfield as an infrastructure partner, bringing his experience as an early investor in AI chip company Cerebras to the venture capital firm. Singh announced the move on August 20, 2026, and will focus on investments spanning hardware, infrastructure software, cybersecurity and physical AI.
The appointment gives Mayfield an investor with both venture capital experience and an engineering background. Singh was previously a partner at Foundation Capital, where he helped source and co-lead Cerebras’ first funding round when the semiconductor startup was still relatively obscure.
Adit Singh brings Cerebras investment experience to Mayfield
Singh’s connection to Cerebras is one of the defining parts of his investment record. Foundation Capital held about a 7% stake in Cerebras by the time the chip company completed its IPO in May, making the firm its third-largest shareholder at that point, according to TechCrunch’s report. Cerebras was then valued at nearly $50 billion.
At Mayfield, Adit Singh joins Mayfield with a mandate covering several areas closely connected to the infrastructure supporting artificial intelligence. His investment focus will include semiconductor and hardware companies, infrastructure software, cybersecurity businesses and physical AI.
Singh told TechCrunch that Mayfield’s semiconductor portfolio was a major factor in his decision to join the firm. He specifically cited investments in Upscale AI, which was recently valued at $2 billion, and Lumilens, which had raised $700 million at a $5.5 billion valuation.
Why the Mayfield role fits Singh’s technical background
Singh’s investment approach is closely tied to his training in electrical engineering and chip design. He told TechCrunch that his technical background allows him to evaluate workloads from the application layer down to the transistor level.
That experience also played a role in his early recognition of Cerebras’ potential. Singh said his electrical engineering background helped him identify the opportunity in the company roughly a decade ago.
Adit Singh joins Mayfield after holding several senior roles in venture capital. Following his time at Foundation Capital, he co-founded Neotribe Ventures in 2017 and spent four years leading the firm before moving to early-stage investment firm Cota Capital.
Mayfield’s scale was another factor
Singh said the changing economics of infrastructure investing also influenced his decision. According to the TechCrunch report, seed-stage infrastructure deals have grown substantially in size, making it harder for smaller funds to participate in some large early-stage financings.
Mayfield manages $3 billion in assets and can write seed checks of as much as $20 million, giving Singh access to a larger capital base for infrastructure investments.
Mayfield Managing Partner Navin Chaddha also has a longstanding relationship with Singh. The two have known each other for 15 years and have served together on the boards of three startups, including Upscale AI and AI unicorn Velaura AI. Chaddha said the discussions about Singh joining Mayfield had continued for a long time before the move came together.
