Attendee density
How many attendees at an event match a specific role, stage, or signal you care about. High-density events deliver more value per hour than large, mixed-audience events - regardless of total headcount.
Attendee density is the most under-discussed metric in event selection. It is not the same as event size. A 500-person AI hackathon may have a density of 5 investors per 100 attendees - useful if you're hiring engineers, useless if you're fundraising. A 50-person curated dinner might have 15 investors per 50 attendees - much higher density, much higher fundraising value, in a tenth the room.
The math of event ROI is closer to attendees in your ICP × your conversion rate × value per conversation than to raw headcount. Smart attendees stop optimizing for prestigious-sounding events and start optimizing for density against their current goal.
The best way to estimate density before committing is to read the guest list (when visible), filter for your ICP, and count. If the answer is fewer than 5, the event is probably not worth your evening - even if 300 people are going.
