The Source ran two of the best social media campaigns of 2025!

For the second year in a row, The Source is featured twice in the best social media campaigns white paper!

‍

These two projects were selected by J'ai un pote dans la com and Metricool, alongside 67 other French and international campaigns, from among more than 500 shortlisted campaigns.

‍

First, the running of Matmut's TikTok account, with a strategy that gives a voice to “young old people,” dynamic and caring seniors who tackle topics related to insurance and the little hazards of everyday life with humor and simplicity to raise awareness among Gen Z. This bold approach has proven successful on the platform, generating more than 90 million views in just a few months.

‍

But also the creation of a UGC campaign for Leboncoin, to enable the brand to test Snapchat's new bidding strategies and thus improve the effectiveness of its advertising investments. The result: the campaign recorded a 37% increase in ROAS and a 36% decrease in cost per purchase!
