Claire Dolo, Maisons du Monde SEO Project Manager

"In the age of AI, it seemed essential to us to call on human editors capable of contributing their expertise on subjects that require advanced knowledge.Assonance met our expectations perfectly. With a collaborative methodology and teams that are available and attentive to our needs, the guides produced are of high quality and much appreciated by our in-house teams. Our needs were directly taken into account, and the fluidity of the exchanges contributed to the success of this collaboration."
David Looses, SEO Specialist Bricoman

"Over the course of our collaboration, Assonance has become a close partner in Bricoman's web content strategy. By initially proposing production adapted to the constraints of our target and our business challenges, we were able to evolve our objectives and convince our teams of the need to develop our message by relying on their expertise. This challenging relationship has enabled us to bring greater value to our content, while at the same time being supported in the development of our internal partners' maturity on these subjects".
Marie Nakhoul, Communications and CSR Manager CAP FRANCE

"We are more than satisfied, both for the professionalism (the content is always well written, adapted to our objectives, and in anticipation of our needs with a real pro-active strength) and for the human quality of our exchanges."
Thomas Schrameck, Marketing Manager Turo

"We've been working with the Assonance teams for several months now, helping us to draft a range of texts in a specific context: that of a platform migration. Since the complex launch of this mission (where rules and constraints were constantly changing), the support, attentiveness, responsiveness, adaptability and availability of the teams have been considerable assets. Thank you to the whole team!
