Membership
Other platforms take 10–20% of every sale. Kolosseum replaces transaction fees entirely with a flat membership. Sellers keep 100% of their margin. Every tier is designed around intent — limiting noise and spam so the marketplace stays focused on real buyers and real sellers.
Browse, discover, and get started. Perfect for casual buyers and new users exploring the platform.
For occasional sellers and price-sensitive buyers who want premium discovery and zero ads.
For active sellers and engaged buyers who want analytics, priority placement, and early access to listings.
Full access. Unlimited everything. Built for power sellers and serious collectors who move volume.
Local messages are always unlimited across all tiers — limits only apply when messaging sellers outside your area.
Why Memberships
The membership model is not just about revenue — it is a design decision. Listing and message limits filter out low-effort spam and tire-kickers. Every user on the platform has skin in the game. That means faster responses, better listings, and a marketplace full of people who are actually here to buy and sell.
Limits force sellers to list items they actually want to move — no stale inventory, no spam posts.
Local messages are always unlimited. Limits only kick in outside your area — keeping outreach intentional and reducing spam from distant low-effort buyers.
No commission on any sale, ever. Your margin is yours. The membership is the only cost.
Boosts, priority messages, early access to listings, and Leak News — the tools scale with your hustle.
