The Trust Layer for High-Value Commerce
Mark3t is the trust infrastructure for high-value resale and luxury commerce. Its first product, the Mark3t Passport, is a portable trust and reputation layer for luxury resale that enables verified reputation and provenance to travel beyond a single marketplace.
Resale is growing 2–3× faster than first-hand retail, on track for a €50B luxury market. But trust hasn't scaled with the volume. Authentication solves products; no one is solving people. Reputation stays locked inside each platform, assets carry no perpetual history, and trust resets to zero on every sale — for buyer and seller alike.
A first mover in an unclaimed category: the rails, not another platform.
Four years embedded across 83+ resale communities; a founder who graded diamonds at Tiffany and transacted at auction — not a whiteboard.
EU Digital Product Passports for textiles and apparel land ~2027–2028. Mark3t is building for that regime before it does.
No exits, no hype: 25 years of domain mastery and a refusal to wait for someone else to build it. Built with passion and grit — a female founder's story.
“Mark3t isn't a marketplace. It's the Stripe of Trust for resale, reshaping how we verify reputation and asset history, in luxury and beyond.”
