Sovereign blockchain infrastructure founded in 2019 by a consortium of four major French industrial players (the Caisse des Dépôts, La Poste, EDF and ENGIE) to deliver digital trust services at a European scale. The platform makes it possible to certify and verify the authenticity of documents and identity data, fighting document fraud with blockchain technology. In 2023, IN Groupe, the maker of France's identity documents and a company wholly owned by the State, took a stake in Archipels on equal footing with the Caisse des Dépôts and La Poste, and now sits on the Archipels Strategic Council. This investment is part of IN Groupe's Digital Odyssey 2025 strategy focused on the identities and digital services of the future. Archipels is a member of the French Federation of Digital Trusted Third Parties (FnTC) and aims to become the European leader in document trust and sovereign digital identity, with a rollout underway across Europe and North Africa. A consortium created in 2019, IN Groupe took a stake in 2023 as part of its Digital Odyssey 2025 strategy, member of the FnTC, rollout underway across Europe and North Africa, active partnership with Vialink and Luminess for blockchain-based KYC

Open-source blockchain protocol providing the most widely deployed tokenized digital product passport technology in the world. Founded in 2017 by four French entrepreneurs including Pierre-Nicolas Hurstel and Frederic Montagnon, Arianee lets brands create a direct, permanent link between a physical product and its owner through dynamic NFTs. These digital passports open the door to new models of customer relationship, post-purchase services and circular economy, including authenticity verification, repair tracking and product insurance subscription. The protocol is compatible with all EVM blockchains and built on a user-owned data architecture (zero-party data), guaranteeing privacy. More than 50 international brands, including Breitling, Lacoste, Vacheron Constantin, Yves Saint Laurent and Fnac Darty, use Arianee to certify their products. $28M raised in total (EUR 8M in 2021, then $20M in a Series A with Tiger Global in 2022), more than 50 partner brands including Breitling, Lacoste, YSL, Fnac Darty and Richemont, 4.3 million NFTs issued, around 73 employees based at La Caserne (Paris), co-founded by Pierre-Nicolas Hurstel and Frederic Montagnon
