Quick hit · A Headland concept build
Buyers and sellers keep saying the best part of the event was a meeting somebody arranged by hand. This arranges them by the hundred - tell it what you are working on, get three people worth your twenty minutes. Try it.
Hosted-buyer programs usually run on a spreadsheet and a very tired coordinator. This one runs on what attendees said they are working on.
Attendees pick their problems at registration. The matcher pairs people who picked the same ones and lands three meetings in both calendars.
Sponsors and hosted buyers fund it - meetings are the product they bought. Twenty minutes, actually relevant.
Meetings held is the number sponsors renew on - and every one is tracked, so renewal is arithmetic.
A concept build, and a starting point: your attendees, your sponsors, your meeting points. The math underneath is the cheap part - the curation is the product.
