Associations and their congresses are changing, and so are we!

The environment in which professional associations and learned societies operate has changed radically.

Colloquium will accompany you on a daily basis in this modernisation and digitalisation movement.

Our objective is to offer our current customers and future partners tools that are in line with the uses of digital technology.

To allow you to follow the organisation of your event live, to control your budget, but also to offer simple and collaborative tools to your committees… this is our objective.

Last May, Colloquium was awarded the innovation prize by IAPCO, the international association of professional congress organisers, for the creation of its budget management platform Colloquium Numbr.

This prize is a real source of pride and the reward for work carried out over 2 years by the Colloquium teams.

With 60 years of experience in the congress industry, we’re reinventing the codes of our profession each and every day with audacity, enthusiasm… and a good dose of digital technology

Let us surprise you!
