What CASTALIE does

CASTALIE is a French B2B provider of microfiltered mains-connected water fountains, founded in 2011 by Thibault Lamarque and headquartered in Boulogne-Billancourt. The company rents and services premium water dispensers to enterprises, hotels, and restaurants across France, with its PURE product line co-developed with CETIM under the NF E01-005 standard and manufactured in France and Italy. Its core technology is a 0.5-micron membrane microfiltration system combined with active charcoal filters that remove chlorine, heavy metals, pesticides, pesticide metabolites, and PFAS while preserving natural minerals, yielding a neutral taste profile endorsed by Michelin-starred chefs and sommeliers.

The business model is anchored in a recurring subscription rental stream that bundles delivery, professional installation, filter replacement, three annual maintenance visits, and a 24-hour repair guarantee. Pricing is quote-based, varying by fountain model, configuration, and volume. Secondary revenue streams include one-time hardware sales of reusable glass bottles, stainless steel gourdes, and branded accessories, plus custom corporate-branded items. CASTALIE distributes through direct enterprise field sales, inside sales for mid-market clients, an e-commerce store for accessories, and an ambassador referral program that rewards converted leads with €300. The company reports 7,000+ fountains installed across 3,000+ clients, 1,600+ companies (including CAC40 corporates), 1,400+ hotels and restaurants, and 15M+ monthly end-users.

CASTALIE is privately held as a SAS (société par actions simplifiée) with €131,705 in stated share capital and approximately 112 employees. It has raised approximately €19M cumulatively across three rounds (2013, 2016, 2020), with the 2020 round led by Ring Capital and SEB Alliance alongside Amundi. Operations remain entirely domestic in France, with no international footprint, parent company, or subsidiary structure disclosed.

Direct peers

• Culligan International: Global leader in B2B water treatment and point-of-use dispensers with a rental/service model very similar to Castalie. Direct competitor for enterprise, hotel and restaurant fountain contracts, especially after its acquisition of Waterlogic.
• BRITA: German-based water filtration specialist with a professional B2B line of mains-connected dispensers. Directly comparable in microfiltration technology, design-led hardware and subscription-based office/HoReCa offerings.
• BWT (Best Water Technology): European water technology group offering point-of-use water dispensers and filtration for offices, hotels and restaurants. Comparable product architecture (plumbed-in dispensers), B2B go-to-market and ESG-led messaging.
• Eden Springs (Primo Water Europe): European office and HoReCa water provider (coolers, bottles and plumbed-in dispensers) under subscription. Closest direct competitor to Castalie in the French and Benelux enterprise water cooler market.
• Waterlogic (Culligan): Now part of Culligan, Waterlogic was a leading B2B mains-connected and bottle-fed water dispenser company. Competes head-to-head with Castalie on enterprise rental contracts, IoT-enabled dispensers and service SLAs.

Emerging players

• SodaStream: Consumer sparkling-water appliance brand (now PepsiCo). Different delivery model (in-home appliance vs B2B fountain) but adjacent category, competing for the same plastic-displacement and sparkling-water consumption occasions.
• Quooker: Design-led instant boiling-water tap brand with growing filtered chilled/sparkling water extensions. Comparable in premium hardware positioning and ESG-friendly in-home/office tap installations, though distribution-led rather than service-rental.

Broad incumbents

• Nestlé Waters: Global bottled water incumbent (Perrier, S. Pellegrino, Contrex). Represents the legacy delivery model (bottled water) that Castalie's plumbed-in fountain directly displaces in enterprise and HoReCa accounts.
• Danone Waters: European bottled water giant (Evian, Volvic, Badoit). Adjacent incumbent in premium still/sparkling water that Castalie's microfiltered, on-premise sparkling option directly substitutes in restaurants and hotels.

Regional players

• Culligan France: French subsidiary of Culligan and the most direct incumbent competitor in Castalie's home market, offering a long-established water cooler and dispenser rental book to French enterprises and HoReCa.
