For entrepreneurs and innovators, it can be hard to find problems to tackle with their expertise or assets. It's like looking for nails to hit with your hammer - but only finding screws.

Our mission is simple: we bring problems to you. We hope that new approaches will be explored this way. And hopefully, our society will be able to tackle its biggest challenges.


We are happy to share with you some of the biggest problems we found in the litterature. Just sign up to receive the newsletter once a week. In return, please tell us what's the biggest challenge in your field!
