What Cryptosteel does
Cryptosteel (legally Cryptosteel SWORD LTD, Manchester, UK) manufactures and sells stainless steel backup devices for the offline storage of cryptocurrency seed phrases, passwords, and private keys. Its core product line comprises the Seed12 and Seed24 capsule systems — built from AISI 304/303 aerospace-grade stainless steel with debossed double-sided character tiles, detachable cores, and PSW-97 tamper-evident security seals — alongside the original Cassette product, all rated fireproof to 1400°C, waterproof, corrosion-resistant, and pressure-resistant up to 150,000 N. The company sells directly to consumers via its own e-commerce store (cryptosteel.com) at price points ranging from approximately $30 (Seed12) to $290 (Seed24 Quintet) and up to $432 for the Liana Box inheritance bundle, and supplements this with bundled co-sells alongside Ledger, Trezor, Blockstream, and BitBox02 hardware wallets, a multi-country European reseller network, and Amazon storefronts across six European and North American marketplaces.
The business model is one-time hardware sales with a modular aftermarket for replacement tiles, seals, capsules, and cotter pins that generates repeat purchases from existing users. Go-to-market is product-led with a 'Backup Finder' recommendation tool, augmented by channel partners, annual #BackupDay educational campaigns, content marketing, and crypto-influencer collaborations. Founded as a concept in 2013 and brought to market through 2015 crowdfunding, the company operates three regional warehouses (USA, UK, EU), ships to over 100 countries, accepts Bitcoin via the Lightning Network, and offers anonymous parcel-locker delivery in the EU — operational features tailored to the privacy posture of self-custody crypto holders. It holds a World Wide Utility Patent on its Capsule design and CCSS Level 3 compliance positioning.
