Supadu Extends D2C Reach with De Marque Partnership
On March 3, 2026, Supadu, a London-based e-commerce and metadata platform, announced a significant partnership with Canadian distributor De Marque. This collaboration aims to enhance Supadu’s direct-to-consumer (D2C) offerings by adding international digital distribution and instant e-book reading capabilities.
The announcement follows closely on the heels of Supadu’s launch of Radley Books, a Shopify-based website solution designed to provide smaller publishers and imprints with a streamlined path to direct online sales. This partnership with De Marque is poised to further elevate the accessibility and reach of digital publications.
Partnership Details
The partnership combines Supadu’s branded publisher storefronts with De Marque’s Cantook distribution network. This network boasts an impressive reach, connecting to over 1,300 online bookstores and 1,800 libraries worldwide, and offers more than 3 million titles from over 3,000 publishers.
Clients utilizing the integrated solution will benefit from a branded D2C storefront along with international distribution capabilities, all without the need to develop separate technical infrastructures for each market. Customers purchasing through a Supadu-powered website will enjoy immediate access to their e-books via De Marque’s browser-based instant reading service, which allows users to open titles in a web reader without the need for file downloads or app installations.
Enhancing D2C Exposure
This partnership is part of a broader strategy by Supadu to enhance its D2C exposure within the publishing industry. In November 2025, Supadu collaborated with Lulu to merge Supadu’s D2C stores and templated Shopify sites with Lulu’s global print-on-demand capabilities. This move was aimed at providing publishers with more comprehensive solutions for reaching their audiences directly.
Additionally, a partnership with Frankfurt-based Bookwire has extended Supadu’s D2C reach into Europe, offering Bookwire’s publishers a Shopify-based website solution integrated with Bookwire’s metadata systems. Furthermore, a collaboration with Books International, announced in 2024, provided BI publishers with D2C shopping capabilities fully integrated with the BI warehouse, including live inventory availability.
The cumulative effect of these partnerships has established a hub-and-spoke model, with Supadu’s e-commerce and metadata layer at the center. Fulfillment, distribution, and reading infrastructure are provided by specialized partners based on format and market needs.
Industry Insights
Sarah Arbuthnot, president of Supadu, highlighted the significance of this partnership, stating, “Publishers want solutions that are powerful, reliable, and easy to implement.” The collaboration with De Marque offers a turnkey path to D2C sales while maintaining the reach, quality, and discoverability of global distribution.
De Marque, based in Quebec, is known for providing library e-book infrastructure across various regions, including France, Belgium, Canada, Spain, and Portugal. They also support the DPLA Exchange and Palace Marketplace in North America. Marc Boutet, president of De Marque, emphasized the shared focus on access, stating, “We are reducing technical and commercial obstacles so publishers can reach more readers, and readers can access books more easily, no matter where they live or how they choose to buy.”
Future Trends in D2C Publishing
The push for D2C solutions at Supadu coincides with a broader industry trend. In January 2026, Independent Publishers Group (IPG) announced a partnership with Norway-based Beat Technology, which also collaborates with Supadu. This partnership allows IPG publishers to sell e-books and audiobooks directly to customers through Beat’s Shelf app. IPG CEO Joe Matthews remarked that 2026 would be “the year IPG releases a whole new turn-key solution for publisher shopping carts across all formats.”
As the publishing industry continues to evolve, the focus on direct-to-consumer sales is expected to grow, providing publishers with new avenues for reaching their audiences and enhancing the overall reading experience.
