Most conference sites are submission directories: organizers add their own events, nobody checks, and half the entries point at dead pages. This catalogue works the other way around. A scraping pipeline finds events, reads each event's own website, and a verification gate decides what gets published: dates, venue and organizer confirmed against the source before a listing goes live.
Because speakers and sponsors are records rather than text, you can turn the database inside out: start from a company and see every event it sponsors, exhibits at or speaks at. That reverse view is what marketing teams use to follow their competitors' event calendars, and it's free to browse.
