Kumulus Water, a Tunisian agri-tech start-up, has secured $3.

5 million in seed funding.

They specialise in Atmospheric Water Generators, turning air into clean drinking water.

The funding will accelerate the development of the larger industrial Kumulus Box for community use.

Operations will expand in Saudi Arabia, France, Spain, and Tunisia, addressing urgent water needs.

These units produce 20-30 litres of water daily, using solar or standard electrical power.

Here's some good news on the sustainable water front. Tunisian agri-tech start-up Kumulus Water has recently secured $3.5 million in fresh seed funding—a tidy sum that's expected to drive the company's expansion into the Saudi Arabian market. Investors behind this latest round include Flat6Labs, Khalys Venture, Plus VC, and Bpifrance.

Kumulus Water specialises in designing Atmospheric Water Generators—commonly known as AWGs—which turn thin air into clean, safe drinking water. Imagine that! It's a concept that genuinely sounds straight out of a sci-fi film, yet it’s already turning heads and changing lives.

These AWGs suck in ambient air through a circular opening at the top, run the air through specialised filters—removing dirt, pollutants, and any nasties—then cool and condense it, mimicking nature's own process of forming dew. Ingenious, isn't it? And they're completely independent units; users can check water production, get maintenance updates, tweak settings based on the weather, all from afar using a handy mobile or web app.

The new funding round is set to significantly speed up the development of their next innovation, the "Kumulus Box"—a larger, industrial-grade atmospheric water generator that's specifically aimed at industrial sites and community-level usage. Alongside that, the money will help ramp up operations not just in Saudi Arabia—where water solutions are keenly needed—but also bolster their presence in France, Spain, and their home terriotory Tunisia.

So far, these innovative machines produce between 20 and 30 litres of drinking water daily, capable of running either on standard electrical power or via solar energy. They've proven especially useful in schools, hotels, remote camps, and communities dotted across Europe, Africa, and the Middle East. I can quite easily picture this technology being immensely useful at some of those far-flung work camps out in the desert, or rural African villages facing severe water scarcity.

Given global water shortages, it's heartening to see ventures like Kumulus Water stepping up. Sustainable tech that's practical, effective, and seemlessly blends into day-to-day life—now that's something Arageek readers can certainly cheer about.
