I believe that design can serve an important and valuable role in society. There is always more than one way to do something. Every time you choose to make a product more sustainable, thought provoking or simply invaluable to a person you are putting good out into the world. Here are 3 companies I have a major design crush on.
au.whogivesacrap.org - They make toilet paper, provide aid and pay themselves a good wage. Right on guys. Everybody wins.
www.projecthdesign.org - "Making positive, long-lasting change in lives and communities".
The way I see it Project H understand the community and use available resources and design to make the place better. Simple and elegant. Plus I have a massive girl crush on Emily Poulton. Watch her Ted Talk "Teaching design for change" here.
www.zaishu.com - Zaishu stools are the bomb! They took a collaboration project and turned it into a viable product.
Working with everyone from street artists in Berlin to kids in Fiji this company practices what they preach and get to have a lot of fun doing it from the looks of it.
