Weinberg Capital Partners, a leading private equity firm specialising in the small- and mid-cap segment, announces the successful closing of its first continuation fund, created to extend its support for Sapian, one of France’s leading providers of hygiene and environmental protection services for living and working spaces.
This transaction, which mobilises a total of €115 million in equity, marks a new milestone in the partnership initiated in 2019 with the investment of the LBO fund WCP#3 in Sapian. The continuation fund, exclusively dedicated to Sapian, will support the company’s growth strategy, particularly through future acquisition opportunities. New investors, including several family offices, are joining the company’s shareholder base alongside existing investors.
Founded in 2019 following the carve-out of the “Hygiene and Prevention” division of the ISS Group, Sapian is now the only operator in the French market offering an integrated range across four essential domains: air hygiene, pest control, sanitation, and fire protection. Under the leadership of its Executive Committee chaired by Fabien Sfez, the company has carried out an ambitious transformation plan, including the digitalisation of its processes, the deployment of new commercial initiatives, and, in 2024, the completion of its first acquisition with the purchase of Groupe Vallier, a specialist in sanitation services.
Sapian now employs over 1,500 people across 41 branches in France and anticipates revenue exceeding €155 million in 2025. The company is entering a new phase of expansion and aims to reach a target revenue of €250 million by 2030.
The continuation fund is financed by Swiss firm Montana Capital Partner’s most recent edition of the Opportunity Secondary program (OSP), acting as lead investor, alongside several existing investors and new partners. Weinberg Capital Partners also participated in the financing. The transaction represents the sixth investment of the LBO fund WCP#4. Launched at the end of 2023 with the acquisition of Arbevel, now Montpensier-Arbevel, WCP#4 is currently more than 50% committed, and its portfolio includes Groupe ProNet, the management company’s first international investment, as well as Cosmogen, Summa, Albaron, and now Sapian.
Founded in 2005, Weinberg Capital Partners is an independent investment company historically active in buy-out capital, which expanded its field of intervention to real estate assets in 2008. In 2020, Weinberg Capital Partners added its capacity to invest in SMEs/mid-caps with a minority strategy focused on sustainable development issues, which offers extra-financial support known as impact, to better prepare companies for environmental and societal challenges. In 2023, Weinberg Capital Partners created a new fund, Eiréné, dedicated to the development of SMEs/mid-caps in the security and defense sector. In 2024, the company continued its growth in private equity with the launch of a co-investment fund, WCP Co-Invest. With €1.9 billion of assets under management, Weinberg Capital Partners is a significant player in the mid-market equity segment in France.
