Sapian buys three firms, adding €10M+ in revenue
What's the deal? French building hygiene group Sapian has acquired Aérolia, Servitec and EC Assainissement, three companies that together generate more than €10 million in revenue. Terms were undisclosed, and all three deals were concluded outside any competitive process.
What each brings: Aérolia, based in Radinghem-en-Weppes, is the largest target and specialises in air hygiene, industrial cleaning and disinfection, serving industry, healthcare and agri-food clients. Servitec, in south-west France, works in air hygiene and fire protection, while EC Assainissement handles wastewater treatment in the Ain department and generates less than €1 million in revenue.
Why now? Weinberg Capital PartnersDealroom has a profile for this one. Try Dealroom → reinvested in Sapian in late 2025 through a continuation fund that raised €115 million, with external growth a priority. Credit lines for acquisitions were set up at that stage and are financing these three deals.
What's the endgame? Sapian — formerly the hygiene and prevention division of ISS, acquired by Weinberg in 2019 — operates in four lines: air hygiene, pest control, sanitation and fire protection. It posted around €155 million in revenue in 2025, with more than 1,500 employees and 41 branches.
The group had completed only one acquisition since Weinberg came on board — Groupe Vallier in 2024 — making these deals an acceleration of its buy-and-build strategy. EC Assainissement strengthens Vallier's positions in the Pays de Gex.
The detail: Aérolia's scope was redrawn before signing. Its Île-de-France branch, which accounted for nearly €4 million in sales, was carved out and stays outside the acquisition. Founders Sébastien Pissonnier and François Tailliez remain operational.
The signal: "Once you have an area of expertise, the ambition is for it to extend across the whole group and be offered in every branch," said Camille Duxin, associate director at Weinberg Capital Partners. The three deals are modest against Sapian's €155 million in revenue, but they mark a shift from a single bolt-on to an active consolidation push in a fragmented market.
