Our history

First audio guide app
Dedicated audio guide app created for the National Museum in Krakow for the "Szymon Czechowicz" exhibition. First experience with the audio guide format on mobile devices.

From the idea of repeatable deployments emerges the multi-tenant AppAudioGuide platform with central CMS. The goal: make modern audio guides accessible to smaller museums without building a separate app from scratch.

First deployment of a branded mobile app under the client's brand. Support for multiple museum departments and temporary exhibitions.
Three new deployments in one year
Silesian Museum in Katowice (flagship branded app), Marie Skłodowska-Curie Museum in Warsaw (PWA deployment), Open-Air Museum in Sidzina. Also a collaboration with the Krzyżowa Foundation on a video guide.
Ecosystem expansion and new legal entity
Launch of ViZoo (AI-enhanced app for zoos). In-house "See It" project — guide to Malta and Gozo (300+ locations). Founding of a limited liability company for new contracts.
