Mayfield Fund is a long-standing, people-first venture firm that backs founders from inception through early scale, with the strongest focus on Pre-Seed, Seed, Series A, and selective Series B. The firm is known for hands-on board partnership, disciplined pacing, and high-conviction investing in AI, enterprise infrastructure, deep tech, cybersecurity, semiconductors, and technology-driven health.
Mayfield sources deals through thematic outreach and internal networks, then two partners build a conviction dossier and present it to the full investment team for a consensus decision. They prioritize "people first" – authentic founders with a strong mission and X‑factor – and evaluate teams before market size or traction. For SaaS, retention and gross‑margin discipline are the top metrics; for marketplaces and consumer products they look for durable usage and network effects. Deal‑breakers include chasing hype without conviction, weak user engagement/retention, and founders who are not a good fit for Mayfield’s hands‑on board involvement. Their model emphasizes a measured cadence, avoiding the sprint‑style investing seen in 2021.
