Founded in 1832 in Avelin in the Hauts-de-France region, Groupe Doublet built its reputation on the manufacture of visibility supports, signage and the equipping of major events. With the acquisition of Ideactif, finalized in January 2026, the family-owned company takes a defining step forward, pursuing its growth through command of the entire event-communications value chain, from strategic consulting to on-the-ground deployment.
Analysis by the experts at Auris Finance, an advisory firm specializing in mergers & acquisitions and financial engineering.
Groupe Doublet, which posted €50 million in revenue in 2024, is integrating Ideactif, its tenth acquisition since 2014. Ideactif generated approximately €16–18 million in revenue in 2024.
A now-complete value chain
Long a specialist in industrial production and event logistics, Doublet is now broadening its offering to creative strategy and brand activation thanks to the expertise Ideactif brings. The Group can thus offer brands, event organizers and institutions a single point of contact covering the entire event lifecycle, from concept to on-site execution, a distinctive model in Europe.
Arnaud Peyroles, founder and president of Ideactif, confirms the strategic significance of the tie-up: “By joining Groupe Doublet, we’re moving up a level: we gain access to industrial resources and a European footprint unprecedented in our field. Ideactif remains the agency of the real, the one that stages the encounter and shifts opinion, but it is now backed by a complete chain, from ideation to deployment. It’s a unique proposition in the market.”
A clear European ambition
Doublet employs more than 350 people across six countries and states its objective plainly: to become the benchmark group for on-site communications in Europe. This tenth acquisition since 2014 is part of a long-standing external-growth strategy aimed at progressively expanding the Group’s scope of expertise, in order to respond to large-scale tenders with an integrated offering that few players can provide at this scale on the continent.
Gaëlle Doublet Colaert, chair of the executive board, frames the ambition: “With Ideactif, a benchmark in consumer-facing events, we become a group that carries these colors all the way through to the experience the public lives.”
