Thesis

Mayfield invests in founders building iconic companies through AI-first innovation and human-AI collaboration. The firm believes the next wave of category-defining enterprises will leverage collaborative intelligence, where AI teammates augment and amplify human capability. Mayfield seeks deep tech founders with defensible innovation, clear market advantage, and the ability to scale globally.

Likely not a fit for

Mayfield avoids consumer apps, pure marketplaces, gaming, crowded markets without differentiation, solo founders without co-founder teams, and business models dependent on rapid customer acquisition without clear unit economics.
