Primary runs one of the most resource-heavy platform models in seed VC with roughly 50 people including 20+ full-time platform operators, making their impact team about twice the size of their investing team, and operates as an explicitly NYC-focused fund that treats seed as a genuinely low-volume business where each partner does only 2-3 deals per year after screening ~100 opportunities. They've engineered a choreographed "founder-sell" experience where founders walk into a room with the entire firm, champagne, and a live presentation showing immediate talent pipelines and customer targets, reportedly yielding 90% win rates when competing for deals.
