Two-sided marketplace

Trade shows were two-sided marketplaces centuries before the term existed, and borrowing the framing sharpens how you run one. The core insight: each side only shows up for the other. Exhibitors pay for access to buyers; buyers spend a day of their life for access to suppliers; the organizer's real product is the match, not the square meter. That's why pricing is asymmetric almost everywhere — exhibitors fund the show, and visitor tickets are cheap or free, because the buyer side is what's scarce and what everyone is paying to reach. The framing also imports a useful vocabulary: liquidity (do participants find what they came for?), cold-start (how do you launch with neither side committed?), and curation (protecting each side's quality for the other). One thing makes event marketplaces unusual, though: they clear once a year, in three days. An e-commerce marketplace can fix a bad match tomorrow; at a show, a failed edition costs a participant a full cycle, and maybe their budget line. That's why pre-show matchmaking carries unusual weight. The common mistake is growing the paying side — selling more booths — faster than the buyer side can absorb.
