We have built an app that suggests daily activities and eco-friendly brands to people who are trying to live more sustainably. When people start to switch to a sustainable lifestyle they need to do a lot of research and find out what they will do on their own. We have helped these people to find those things, do it with a community and see the collective impact. Previously we worked on Nemria and Carbofil is the result of this learning process!
