Regreening the Planet with Water From Air


Have fun.

Make impact.

We are a young, ambitious, high tech startup with a mission. Our technology is inspired by nature. By looking at plants and animals in dry coastal areas, we developed a temperature-sensitive smart material that collects water from a massive, untapped reservoir: the air around us. Allowing us to irrigate trees, make drinking water or dehumidify. Fully off-grid, without adding energy and affordable.

Our team currently consists of 5 people and we are expanding. Scroll down to find out more about what we do, our mission, what it's like to work with Sponsh and how you can be a part of our dream team.

Our Mission

To Provide Water From Air to 1 Billion Young Trees by 2040

We Are a High-Tech Green Company

As with nature, our technology is both highly complex chemistry and simple real-life application. The technology behind our material is based on 8 years fundamental research and two publications in 2013 and 2016 by dr Catarina Esteves in the highly regarded scientific journal Advanced Materials. See a video of how the material absorbs and releases water under the microscope. 

Catarina is also co-founder and chief scientist of Sponsh. After founding Sponsh to commercialise the innovation, we improved and scaled-up the material. Our technology is patent pending. We are still in the development phase and chemistry product development forms the core of our startup.

The potential applications of our technology are massive

Our patent-pending technology enables making drinking water in remote areas, irrigating crops when there are no other water sources or dehumidifying greenhouses with very little energy. Apart from these applications, we have been approached by many different industries, including diaper, air conditioning and LNG tank producers. 

Our first product is a water producing tree guard. To help young trees grow in areas where this is otherwise not possible. Regreening the planet with water from air
