Funny name, serious business

We make eco-friendly products and donate 50% of our profits to provide clean water and help build toilets for the billions of people who lack proper access. So far, we’ve contributed over $18 million AUD (roughly $12.5 million USD) to fund sanitation projects around the globe. Basically, we’re really good at doing good. 

With hubs in Australia, the Philippines, China, the US, UK and Europe, our amazing team of 200+ work to make the biggest possible impact for people and the planet. Over the next couple of years, we’re hoping to increase our annual donation tenfold to get us closer to our dream of everyone in the world having access to clean water and sanitation services.
