A large number of people know more about the world and how stuff works than a single person, right? Obviously, we want to understand how the world works, but we think that ideas from people like you and me are very very important: we want to understand the world together! We take seriously to make live better for people, so our job is to help those who are working on the really hard problems. Most of the time, our people sit behind closed doors, read papers, type into their computers and — by chance — miss day-to-day problems of people like you and me. We help them to be open and change their way of finding things out about the world. Being open is important and the key-word for us: it is at the heart of what we do. If you you want to work like this, you should come to us, we are living in a very cool city, you can visit with your horse, if you want — seriously!One approach of our job is to find new ideas and questions that are important for people. There are many good ideas already out there, we just need to catch them. We are wondering what different groups of people — we call them crowds — think about several problems they face in their day to day life. They should not be ignored and taken seriously. With this, we can find new problems that no-body ever thought of and give them to our people to work on these problems.
