Kadeya

Kadeya operates what it describes as the world's first closed-loop beverage system: self-contained vending kiosks that fill reusable glass and stainless steel "infinite bottles" on demand at the point of service, then accept the bottles back for automated cleaning, sanitizing and refilling. Stations tap into the local water line, run water through advanced filtration, and dispense still filtered water as well as carbonated, flavored and branded drinks; where plumbed water is unavailable, the system can run from water tanks or delivered water. Units require 220V power and are ruggedized for outdoor-adjacent use, though the company notes they work best under cover. Users scan a QR code at the station to order, receive a chilled pre-filled bottle in under five seconds (or a bottle filled on demand in under seven seconds), and return the bottle to any station [0][2][4][6].

Alongside the hardware, Kadeya provides an employee web app and corporate dashboard that track individual hydration and impact metrics, supply hydration data for OSHA reporting and carbon data for ESG accounting. The company positions the system against single-use bottled water, water coolers, fountains and conventional vending machines, arguing it removes on-site plastic waste and associated clean-up labor while remaining at or below the cost of single-use bottles. The founder frames the company not as a beverage brand but as a distribution platform — a new route to market for drinks that decentralizes the linear beverage supply chain to the point of use [0][1][2][4][6].

Founding story

Founder and CEO Manuela Zoninsein began her career as a climate correspondent in China, where she launched her first company, and later started a second venture in Brazil that became an online marketplace for smallholder farmers. Observing both countries shift from reuse to single-use packaging, and while later working a corporate technology job at Palantir in the US, she questioned why a new container is manufactured for every bottle of water consumed. Drawing an analogy to bike-sharing networks, she designed Kadeya around reusable bottles, optimized climate impact and broad access to drinking water. She holds an MSc in Modern Chinese Studies from St Hilda's College, Oxford (matriculated 2010). Kadeya was founded in June 2020 [1][4].

Business model

Kadeya places its vending stations at customer worksites and sells beverages on a "hydration as a service", pay-as-you-go basis, with pricing quoted per environment and positioned at or below the cost of single-use bottled water. Bottles remain part of the service loop; a 1% bottle loss rate is factored into the fee, and sites are responsible for purchasing additional bottles if losses exceed that threshold [4][6].

Recurring pay-as-you-go service fees for beverages dispensed at installed stations, marketed as hydration-as-a-service rather than equipment sale [4][6].

Traction

In a pilot on one of the largest construction sites in the US, Kadeya started with 20 employees over several months, reported a 99% bottle return rate, moved from a prototype to full closed-loop stations, deployed seven stations on the job site, and eliminated more than 250 single-use plastic bottles; the company cites a 75-77% reduction in carbon emissions versus PET bottles. It also reports a 41% increase in employee hydration and that 52% of employees felt more connected to sustainability goals. The website states availability is sold out through 2025 with pre-orders open for 2026 [0][2][4][6].

Latest developments

The company reports being sold out of station capacity through 2025 and taking pre-orders for 2026, while serving a waitlist of construction, manufacturing, military and fulfillment customers [4][5].
