Mayfield

Mayfield is led by Managing Partner Navin Chaddha, who guides the firm's AI-focused investment strategy. The firm operates a partnership model with multiple investing partners who participate in sourcing and underwriting. Specific decision-making mechanics—such as the size and authority of the investment committee—are not publicly disclosed.

Mayfield positions itself as the first institutional investor for early-stage AI founders, with 70% of its investments made at inception. The firm cultivates deal flow through deep founder relationships, often engaging before a company has demonstrated product-market fit. Mayfield's multi-decade track record and network of over 500 portfolio-company alumni also serve as a proprietary sourcing engine.

Mayfield concentrates on the earliest stages of a company's life. The firm states that 70% of its investments are made at inception or the seed round. It does, however, selectively participate in later expansion and growth-stage rounds for existing portfolio companies.

Mayfield's most recent stated focus is on AI companies, and it operates as a generalist tech investor within that domain. The firm has historically avoided sectors like hard industrial tech, space, or life sciences. There is no public evidence of recent activity in energy transition, heavy manufacturing, or non-software medical devices.
