The Evolution of Funxtion


Funxtion is born

The gym floor is revolutionised with playful, energising and functional workouts that enhance the in-gym member experience.


Funxtion digitised

In-gym functional floor spaces got an upgrade with The Funxtion Experience Station (FES) that streamed digital workouts, and later virtual classes.

Funxtion Branded Member App


White Label Member App

Omnichannel content delivery is enabled with Funxtion’s branded member app that gives gyms the tools to connect with their members in and outside their facility.


New vision

Funxtion focuses towards building an open SaaS Platform that allows gym operators to access, upload, and customise the digital fitness content they want and share it at scale with their members via the delivery devices of their choice.
