Paris, November 3, 2026
AREV announces the sale of its stake in Mozaik, formerly known as Toutapprendre, to EMZ Partners and the management team.
Founded in 2008, Mozaik has established itself as the leading digital content platform serving French employee representative committees (Comités Sociaux et Économiques – CSEs) and libraries. The Group offers a comprehensive range of content covering all key segments, from e-learning and homework assistance to personal development, newspapers and magazines, books, comic books and video on demand, alongside ticketing services and complementary software solutions. Its offering is supported by an extensive content catalogue, regularly expanded through close relationships with publishers and partners.
Since AREV’s investment in November 2022, Mozaik has tripled in size, strengthened its organisation, accelerated its commercial development and completed four strategic acquisitions. The integration of these businesses has enabled the Group to broaden its offering, expand its addressable market and enhance its value proposition. Today, Mozaik serves nearly 3,000 CSE clients.
EMZ’s investment is intended to support Mozaik in increasing the penetration of its offering among CSEs, expanding its content catalogue, developing additional services and continuing the targeted buy-and-build strategy initiated alongside AREV.
Marc Wacongne, President of Mozaik, commented:
“We are proud of Mozaik’s transformation, having grown from 22 employees when AREV invested in November 2022 to 150 today. The rebranding from Toutapprendre to Mozaik reflects the significant expansion of our offering. We are now able to provide CSEs and libraries with a platform covering an ever-growing range of content.
This transformation has been made possible by AREV’s support and strong commitment. We approach the next chapter with confidence and ambition, determined to continue expanding our offering, developing our services and strengthening our relationships with clients and end users.”
Xavier Geismar and Julien Lammoglia commented:
“Partnering with ambitious entrepreneurs to help them transform their organisations and accelerate their growth is at the heart of what drives us.
Our partnership with Marc, Arnaud and their teams illustrates our approach: building relationships based on trust, sharing a common ambition and providing strategic support at critical stages of growth.
We firmly believe that Mozaik now has the capabilities and growth opportunities to continue broadening its offering, accelerating its acquisition strategy and strengthening its market position.”
