Audrey Lucas
Partner - Charter & Marketing Director - BGYB

We brought in If/Else agency to implement HubSpot within our company. The tool is incredibly powerful, but it really needed the support of a serious agency to be properly set up. Having an outside perspective on our organization was also key to rethinking our processes and starting off on the right foot.

Thank you, If/Else agency (a huge thank you to Oussama for managing the project, and to Garance and Luc for their support throughout).
Xavier Lagrange
Executive Education Manager - EFREI

[...] The team demonstrated excellent listening skills and a keen understanding of our challenges.  We highly recommend if/else agency for the quality of their support, their professionalism, and their ability to integrate effectively into a project team.
