The round was backed by Bpifrance (via France 2030 SGPI and the Île-de-France Region), regional VCs (PlusVC, Khalys Venture, Flat6Labs), family offices from Europe and North Africa, prominent startup founders, and Spadel, one of Europe’s leading bottled water companies.

This strategic investment marks a major step in Kumulus' mission to provide decentralised, sustainable drinking water in regions facing water scarcity or lacking reliable infrastructure.

“We’re deeply grateful to our existing and new investors for their trust and continued support,” said Iheb Triki, CEO and Co-Founder of Kumulus. “We are especially proud to welcome Spadel as a strategic partner – their long-term commitment to sustainability and innovation closely aligns with our values. Their involvement is a strong vote of confidence in our technology and our vision.”

“We believe the world needs complementary solutions to address the growing challenge of drinking water scarcity,” added Clément Yvorra, Global Business

Development Manager at Spadel. “What convinced us is Kumulus’ ability to produce water locally – without packaging or transportation – offering a truly sustainable alternative.”

The funds are already being deployed to:

• Accelerate the development of Kumulus Boks, a new high-capacity line of atmospheric water generators designed for industrial and community-scale use
• Strengthen Kumulus' presence in France, Spain, and Tunisia
• Support expansion into Saudi Arabia, a key market where sustainable water solutions are critically needed

As global water scarcity intensifies, Kumulus Water offers a clean, scalable alternative to bottled and piped infrastructure – reducing plastic waste and ensuring water access in even the most remote or underserved locations.
