We’re an early phase start-up with a Big Hairy Audacious Goal to provide all coastal communities and regions affected by drought with easy and affordable water. There are many ways you can support that goal. Or contact us at hello@sponsh.co

Join us as a volunteer or intern

We’re in the early phases and can certainly use help. Are you interested in testing the prototypes, supporting our marketing and communications or setting up connections in other parts of the world? We’d be glad to get you on board.

Testing the prototypes or pilots

We have several partners where we are testing the prototypes. Are you interested in testing the prototypes or pilots at your farm, garden or estate?


With the current development pace, we will soon be hiring staff. In particular we’ll soon need a bright chemist with an entrepreneurial spirit. Read more about our team here


Currently we are not seeking investors. However, in the future we will need support from investors to scale-up. Interested in investing?
