US early + growth specialists
Below tier-1 sits a denser layer of US-focused funds. Some specialize by stage (First Round, Initialized at seed; Insight at growth), others by sector (Khosla on deep tech, USV on networks and crypto). For most founders raising in the US, these are the funds where actually-relevant warm intros pay off — and where a sharp Claude Fundraiser deck score on the 7 dimensions they read for is the difference between a pass and a meeting.
Early-stage specialists
Best for: Seed-only, B2B + consumer; deep platform and dorm-room program for portfolio support.
Best for: Pre-seed + seed, technical founders, often pre-revenue with strong product signal.

Best for: Data-driven sourcing across consumer + enterprise; strong recruiting and talent operations.
Multi-stage with strong early presence
Best for: Deep tech, climate, healthcare, AI infra; tolerant of long capex/R&D cycles.
Best for: Generalist with strong health, fintech, and B2B SaaS positions; growth + early.
