Zero-party data

Events are a zero-party data machine that most organizers underuse. Every registration form, matchmaking profile, and session-interest question is a person telling you directly what they want — no inference, no tracking, no guesswork. That directness carries commercial weight in two directions: it's the highest-quality input your matchmaking and recommendations can get, and it's the cleanest data position under privacy law, because the person knowingly handed it over for a stated purpose. In practice, collecting it well is a design problem. Ask questions people have a reason to answer — "tell us your interests so we can recommend exhibitors" converts far better than an unexplained form field — and keep the ask short enough that answers stay honest. The common mistake is collecting it and then visibly ignoring it: an attendee who declared their interests and receives generic recommendations anyway learns that your forms are theatre, and answers accordingly next year. One honest nuance: volunteered data is truthful but aspirational. People report the buyer they'd like to be — senior, strategic, budget-holding — and their on-site behaviour often tells a humbler story. The strongest event data strategies pair zero-party declarations with behavioural signals rather than trusting either alone.
