Contact-data platforms are organized around people: emails, direct dials, job changes, intent topics. Event participation is a side effect in that model — a line that may or may not appear on a company profile, sourced secondhand.
ConferenceGrid inverts it. The catalog is organized around event editions — 3,651 upcoming ones — and each edition's sponsor, exhibitor and speaker rosters are read from the event's own published pages, then re-verified nightly. Look up any company and you get its full event footprint: every booth, every sponsorship, every talk, across every edition tracked. Sales teams use it to plan around where target accounts will physically be; marketing teams use it to watch competitor event spend.
The two aren't substitutes. If you need phone numbers, keep your contact-data provider. If you need the event layer, this is it — and the browse tier is free, so you can check coverage on your own account list before paying.
