• Kumulus Water raised USD 3.5M in seed funding to scale its sustainable, decentralized water generation technology across key global markets.
• The startup’s AWGs convert air into clean drinking water, targeting regions with water scarcity and limited infrastructure.
• Funding will accelerate Kumulus Boks development and support expansion in Europe, North Africa, and Saudi Arabia.

Kumulus Water

What happened? Paris-based climate tech startup, Kumulus Water raised USD 3.5 million (EUR 3.1M) in seed funding. The round was backed by Bpifrance, PlusVC, Kalys Venture, Flat6Labs, and Spadel.

Clément Yvorra, Global Business Development Manager at Spadel, said “ What convinced us is Kumulus’ ability to produce water locally — without packaging or transportation — offering a truly sustainable alternative.”

Who are they? The startup builds atmospheric water generators (AWGs) that transform air into safe drinking water. Furthermore, it aims to provide decentralized, sustainable drinking water in regions facing water scarcity or lacking reliable infrastructure.

Water

How does it work? The machines cool filtered air, condensing it into water droplets. These droplets flow into a storage tank and pass through multi-stage filtration to remove contaminants.The machines produce 20–30 liters of drinking water daily and can operate on standard electricity or solar power. 

Additionally, the machines’ design allows for off-grid operation and allows for operations without infrastructure. Thus, the startup is already serving schools, hotels, and communities across Europe, Africa, and the Middle East.

The system is fully autonomous, allows for remote monitoring and control via a mobile or web app. The app allows users to track water output, receive maintenance alerts, and adjust settings based on local weather conditions.

What is next? With the funding, the startup aims to accelerate the development of Kumulus Boks. Kumulus Boks is a new high capacity line of atmospheric water generations designed for industrial and community scale use.

Additionally, it aims to strengthen its presence in France, Spain and Tunisia. Most importantly, it aims to expand into Saudi Arabia, a market where there is a need for sustainable water solutions.
