PostScriptum

What PostScriptum does

PostScriptum is a Greek private limited company founded in 1991 and headquartered in Athens, specializing in the design, digital strategy, and implementation of cultural heritage management projects for museums, archives, libraries, foundations, and public cultural bodies. Operating with 11-50 employees over 35 years, the firm combines proprietary and licensed software products with professional services to deliver end-to-end digital transformation across the cultural sector.

The company's core technology portfolio centers on MuseumPlus—a globally proven museum management system with 900+ installations worldwide—for which PostScriptum serves as the exclusive zetcom representative for Greece, Cyprus, and Southeast Europe. Complementary proprietary and open-source products include ArchiveMax (archive management based on AtoM), Omeka S (digital publishing), and internally developed platforms eCulturePlus, Exibo, and Smartify for digital curation, exhibition, and audience engagement. Technical capabilities extend to VR/AR applications, Matterport 360-degree virtual tours (deployed at the National Archaeological Museum with 450 viewpoints across 36 halls), and an IoT-based preventive conservation system developed through the HORIZON 2020 Collection Care project. All implementations comply with international documentation standards (Europeana, ISAD-G, National Documentation Centre).

The business model operates across three revenue streams: software licensing and customization (MuseumPlus, ArchiveMax, and proprietary products with pricing provided on request); professional services and consulting covering digitization, documentation, digital strategy, and EU funding navigation; and EU-funded project contracting through programs including HORIZON 2020, Erasmus+, EPAnEK, and Creative Europe. Customer acquisition is sales-led and relationship-driven, targeting cultural institutions primarily in Greece and Southeast Europe, with selective international projects (notably a 2021 cultural diplomacy engagement in China). The firm's client roster includes Greece's most prestigious institutions—Acropolis Museum, National Archaeological Museum, Onassis Foundation, Benaki Museum, MOMus, and the Greek National Opera—anchoring a diversified institutional base despite a public-sector concentration.

Emerging players

• Cuseum: US-based digital engagement and interpretation platform for museums and cultural institutions. Overlaps with PostScriptum's Smartify and Exibo offerings in digital audience engagement and interactive experiences.
