Who we are

Neofonie Mobile was founded in 2008 with the birth of the iPhone and the resulting rapid growth of the app market. Since then, it has helped companies in a range of industries implement tailored business-to-consumer and enterprise apps. We rely on cooperation built on partnership, whatever the technology or the scenario. Our agile team develops native apps, cross-platform apps and web apps to meet specific requirements.

Together with digital agencies Neofonie and Neofonie Polska, UX agency ION ONE and AI agency ontolux, we create unique digital products with impressive levels of user-friendliness and technical perfection across all channels.
