Mark3t is the trust infrastructure for high-value resale and luxury commerce. It issues the Mark3t Passport, a portable trust and reputation layer that enables verified reputation and provenance to travel beyond a single marketplace. Founded in 2026 by Nicole A. Reznic (Founder & CEO). Full founder background: nicolereznic.com. Headquartered at 66 Avenue des Champs-Élysées, Paris, France, and operated by Zernica Corp dba Mark3t SASU.

Mark3t was born from a simple belief: luxury resale should be built on trust, not hope.
I'm Nicole. Before I built Mark3t, I spent over twenty-five years inside the infrastructure of luxury retail and resale, as a Graduate Gemologist grading diamonds at Tiffany & Co., handling UHNWI transactions at Christie's, then building CRM and client-intelligence systems for dozens of financial, luxury, and consumer brands across France and Belgium.
I've also been a longtime Hermès collector and independent reseller myself, so I've felt firsthand how broken this system is for the people trying to keep it honest. I even got scammed myself, which led me to question why every platform is a black box and why we leave so many shadowy spaces in the resale process for fraud to safely hide.
I spent 4+ years in 86+ resale communities, listening, learning, and frustrated. I've watched resellers lose 10 to 45 percent of a sale to platform commissions, wait up to 30 days to get paid, and pay to authenticate the same item over and over because no verification travels between platforms. A power seller with years of five-star reviews on one platform starts every new platform at zero. That's not a supply problem. It's a trust problem, and nobody who actually understood luxury client data was building the fix.
Real platforms deserve real people, real products, real transactions, and proof that's clear, evident, and fair. Circularity only works when buyer, seller, and vendor all trust the same rules, like in retail. In resale, no one has created these frameworks yet.
People don't trust platforms.
They trust people.
