KRNWTR+

What KRNWTR+ does

KRNWTR+ (also trading as Zereau Drinks) is a Dutch social enterprise founded in 2010 and headquartered in Amsterdam that designs, sells, rents, and services professional water tap systems for the office (kantoor) and hospitality (horeca) markets in the Netherlands. The core product, the KRNWTR WaterTapinstallatie, connects directly to the existing municipal water line and delivers filtered, chilled, and optionally carbonated still and sparkling water through table-top, built-in, freestanding, and wall-mount form factors. The filtration module is certified to NSF/ANSI 42 and 52 standards, is manufactured per Regulation 2023/2006/EC, and is rated to remove 99.999% of substances larger than 0.2 microns (including microplastics, PFAS, lead, and medication residues) while retaining minerals such as magnesium and calcium; a 2 kg CO2 bottle produces approximately 300 liters of sparkling water at roughly €0.10 per liter.

The company monetizes through a dual hardware model — a 5-year subscription rental at €129/month that includes full service, maintenance, and filter replacement, and a one-time purchase at €3,555 plus a separate €37.50/month service contract — supplemented by recurring consumables (filter and CO2 replacement), natural limeade syrups sold via the company's webshop, and reusable stainless-steel water bottles. KRNWTR+ sells primarily through direct B2B field sales targeting hospitality venues and corporate offices, with channel partnerships through Vermaat (hospitality operator), Sligro (foodservice wholesaler), and Cookies Catering for account management. Named customers span large Dutch enterprises (KLM, Bilderberg, ARTIS, HANOS, Landal, Flexport, Xebia, Shell) and SMB/mid-market accounts (Renato's, Mossel & Gin, La Vie Meeting Center, Social Impact Factory), with cumulative 2025 impact reported at 23.5 million bottles avoided and 2 million kg CO2 saved. The company is privately held as a Dutch B.V. (KVK 71620915), led by CEO Babs van de Voort, with no disclosed institutional funding and an 11–50 employee headcount range.

Others

• Pentair: Global water treatment and filtration company supplying residential and commercial filtration components and systems. Adjacent through filtration technology supply chain; not a direct dispenser competitor but an upstream infrastructure provider to the category.

Broad incumbents

• EcoWater Systems: Water treatment company offering point-of-use filtration and commercial water solutions globally. Comparable filtration technology and dealer/service network, though more weighted toward residential and whole-building systems than tap-format horeca/office installations.
• BWT (Best Water Technology): European water technology group offering point-of-use filtration, water dispensers and coffee/water solutions for horeca and offices. Competes with KRNWTR+ on commercial filtration but with a much wider product portfolio and multi-country footprint.
• Culligan: Global water treatment and bottled/bottleless water service company serving residential, office and horeca customers. Overlaps with KRNWTR+ on commercial dispensers and service contracts but operates at much broader scale and across many product lines.

Direct peers

• Waterlogic: Waterlogic (now part of Culligan) provides bottleless water coolers and dispensers for offices and hospitality with subscription service models. Directly comparable product (point-of-use filtered/chilled/sparkling dispensers) and recurring-revenue business model.
• BRITA Professional: BRITA's commercial division sells filtered water dispensers and filtration systems to offices and horeca across Europe. It is the closest direct competitor to KRNWTR+'s countertop and under-counter water tap offering, and overlaps on NSF-style filtration certifications.
• Wells (The Water Cooler Company): UK-based provider of bottled and bottleless water coolers for offices and hospitality. Closely comparable subscription-style dispenser business targeting the same office/horeca customer segments as KRNWTR+.

Regional players

• Zip Water: Australia-based provider of instant filtered boiling/chilled/sparkling water taps for offices, hospitality and healthcare. Comparable on tap-form-factor dispensers and sustainability-driven bottleless proposition, but primarily serves APAC markets rather than Europe.
• Quooker: Dutch manufacturer of boiling-water taps sold into kitchens and offices. Comparable on tap-form-factor B2B distribution in the Netherlands, but Quooker focuses on hot water rather than filtered chilled/sparkling water.

Emerging players

• SodaStream Professional: Commercial extension of SodaStream providing countertop sparkling-water makers and refillable CO2 cylinders to offices and horeca. Overlaps with KRNWTR+ on sparkling water on tap and consumable CO2 revenue, but does not match the integrated filtration pipeline model.
