What RoyalPosthumus does

Royal Posthumus, legally Koninklijke Fabrieken Posthumus B.V., is a Dutch manufacturer and direct-to-consumer retailer of stamps, nameplates, signage, engraving, and sealing products, founded in 1865 and headquartered at an Amsterdam factory site (Oderweg 2, 1043 AG Amsterdam). The portfolio spans more than a dozen core categories including office stamps, date stamps, branding irons, wax seals, embossing stamps, metal stamps, lead sealing tools, name badges, brass name plates, wayfinding signage, and foil printing equipment, with an own-brand line (POSTA) alongside third-party brands such as Trodat, ImpressArt, and ATOMA. The underlying technology combines physical engraving capability across materials (wood, leather, cardboard, metal, plastic, food) with an e-commerce customization workflow that accepts uploaded logos in common formats (jpg, png, pdf, ai, eps) and converts them to black-and-white, mirrored artwork for stamping.

The business operates primarily as an online shop at royalposthumus.nl serving the Netherlands and Belgium, with a parallel reseller/dealer program ("wederverkoper worden") for channel distribution. Customer segments include individual consumers (personalized stamps for invitations, gifts, and correspondence), SMBs and professional offices (logo and address stamps), artisans and makers (product branding), and education (teacher feedback stamps). Named enterprise customers publicized for signage work include Heineken, Uber, KNVB, Rijksmuseum, and Batavia Stad.

Revenue mechanics are one-time purchases of customized or standard products, with no subscription model; pricing examples include €9.76 for a Trodat stamp cushion and €33.07 for a Posta plombeer tool, with €5.95 standard shipping and free shipping above €75. The company markets itself on 160 years of heritage, factory-direct supply, and a claimed "largest assortment" positioning, supported by a content marketing blog ("De Stempelkrant"), customer reviews via Feedback Community, and Klarna as a checkout payment option. Ownership is private with no disclosed parent, subsidiary structure, funding rounds, or M&A activity in the input data.
