An open-source PHP/Symfony platform unifying PIM, DAM, CMS and MDM on one codebase, for teams with in-house developers or an integrator partner rather than a marketing team wanting to self-serve.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A product experience management (PXM) platform for brands and manufacturers that centralizes and syndicates product data to retail and ecommerce channels.
