YTY, a Paris holding company for ownership and transmission protocols

YTY is a French holding company — a société de participations — founded by Olivier Cordoleani and registered as YTY (SIREN 887 663 201) at 59 rue de Ponthieu, Bureau 562, 75008 Paris, France. YTY holds the RELICKEEPER® trademark (INPI n° 5219962) and runs the projects of an ecosystem dedicated to ownership, memory and physical transmission: RELICKEEPER and Photonumerique.

YTY designs and protects the projects of the ecosystem. One exception: RELICKEEPER, which YTY edits and sells directly. It is not a startup, not a SaaS company, not a cloud service, not an automation platform, and not a speculative venture. Its world is materiality, transmission, real ownership, proof, memory and the culture of the physical object.

The ecosystem whose projects YTY runs

YTY holds the RELICKEEPER® trademark (INPI n° 5219962), the Card's registered design and the patent application, and edits and sells RELICKEEPER directly. The .//. mark struck on the Card belongs to Olivier Cordoleani and is used by YTY with its owner's consent; a licence agreement is being formalised. It runs the RELICKEEPER services itself (relickeeper.shop online sale, relickeeper.art gallery) and is the contracting party of the terms of use and sale.

RELICKEEPER® is the ecosystem's flagship guardianship protocol, owned, edited and sold by YTY. It is incarnated in a physical card and its Seals — a living certificate that links cultural objects to their provenance through a physical gesture. RELICKEEPER is offline-first: the protocol does not depend on a third-party platform, an online account or a marketplace to operate. It carries no speculation and no secondary market.

The RELICKEEPER brand is exposed through public tenants organised by function, not through separate brands:

  • Shop — the only point of sale for the Cards, the NFC Seals and their accessories. Live at relickeeper.shop.
  • Gallery — limited-edition creative assets compatible with the Card, such as acrylic-glass prints with integrated Seals. The Gallery is not a point of sale for the Cards or Seals themselves — only the Shop is. Live at relickeeper.art.
  • Corporate — the RELICKEEPER corporate site: team, patent application, press, legal notices. Live at relickeeper.fr.

The Corporate tenant is live at relickeeper.fr and the Shop tenant at relickeeper.shop, both since September 2026, and the Gallery tenant at relickeeper.art since October 2026.

Alongside RELICKEEPER, the ecosystem also includes Photonumerique (photonumerique.com) — a curated gallery of open edition artworks on acrylic glass, an aesthetic entry point into the ecosystem.

Founder

Olivier Cordoleani is the founder of YTY and president of YTY. He is the co-creator of the original B.A.T. video game (with Hervé Lange, published by Ubisoft, 1989) and carries the vision, narrative coherence and cultural authority of the ecosystem. His personal site: cordoleani.com.

What YTY is not

YTY does not guarantee the works or products of third-party brands. Apart from RELICKEEPER, which it edits and sells directly, YTY does not sell to end customers. It carries no speculation, no secondary market, no financial product. The B.A.T.® trademark is a personal asset co-owned by Olivier Cordoleani and Hervé Lange — it is not a YTY asset and must never be described as such.
