Trust can be measured.
High-value commerce deserves better tools.
A comprehensive infrastructure, centered on trust.
Today, trust in resale is invisible, locked in DMs, platforms, and memory.
Mark3t makes it visible, verifiable, and portable, so it finally works in your favor.

Resale runs on trust.
The system runs on friction.
Not a demand problem.
A system problem.
- Platforms take 10–45% in commission before you even cover shipping or authentication.1
- Authentication you paid for on one platform doesn't travel, so you pay again to list on the next.
- Payouts can lock for up to 30 days. Unsold pieces sit as dead capital.2
- Buyer conversations scatter across Instagram, WhatsApp, spreadsheets, and memory.
- A good listing takes 30 minutes, every cross-list adds more, on every platform.
- Full-time resellers can spend up to 70 hours a week, sometimes, sourcing and listing.3
- Your reputation is locked to each platform. Move, and the history stays behind.
- You re-prove authenticity to every new buyer and every new channel.
- Off-platform, there is no shared trust system, so fraud has room, and the loss is yours.

Mark3t is opening to a private founding cohort.
The first 100 verified resellers, chosen by reputation, help test and shape the platform from the inside. Select founding members may be selected to become Mark3t Circle Members, the advisory group governing Mark3t.
Founding Cohort
Invite-only. Reviewed by hand. Limited to the first 100 resellers who help build the platform from the inside.
Waitlist
If you are not approved for the Founding Cohort, you may apply for future waves of invitations. This will add you to our mailing list so we can keep you updated on our progress.
- Mark3t is the trust layer for luxury resale. It's a layer of tools built to give verified sellers, buyers, and authenticators a transparent, complete verification system, transaction history, and a trust-first architecture that rewards good commerce with long-term relationships. It's calibrated specifically for high-value commerce.
- We're currently in an invite-only building phase. Mark3t isn't a place to buy or sell. That still happens through the channels you already use. We add the trust layer and tools that bring transparency, clarity, and digital traceability to people first. You keep selling where you sell; we make that work more credible to new clients and partners.
- The Mark3t Trust Passport is a single, portable profile showing a member's verified identity, transaction history, authentication record, and dispute history through the many platforms they sell and buy on. The trust score summarizes that record on a 0–100 scale, and it's recognized across every platform the member works on.
- Professional resellers, trusted buyers, service providers, and authenticators in the luxury resale market. Trust profiles for buyers aren't live yet, but you can join the waitlist to be notified when buyer verification opens, and request access to our private community in the meantime.
- Identity is confirmed once, privately, at the start. From there, each verified sale, authentication, and resolved dispute adds to the seller's trust record. Many factors are weighed together to build a complete picture of who you are and how you work.
- Mark3t is opening through a private founding cohort. Request founding access on our site. Every application is reviewed by hand. If you're not accepted into the Founding Cohort, you can join the waitlist for a future wave.
