About ANIXE Hellas

We were "born" in 2014 from one of the biggest touristic group of companies, the FTI GROUP, as an initial step of automating the back-end workflow of the travel industry. We started as Project Beagle and seemed more like a project, providing support on existing applications. Through time, though, we created new goals, have grown rapidly and ended up exceeding our own limits. And now, as ANIXE Hellas we have become a fully-functional delivery center combining software engineering, design and support services, building software products that numerous destinations around the globe use.


Our mission is to create a new holistic software product for the travel industry like any other has ever existed before, transforming the personal travel from a fragmented, siloed process to a fully integrated, interactive and intuitive one.
