Meet the team

Hi, we are 100WEEKS! We are based in the Netherlands, Rwanda, Ghana and Uganda. (We use Zoom a lot.) The core of our organization consists of a small permanent team surrounded by a larger circle of professionals that work for us on an ad-hoc basis. This keeps our overhead low and allows us to adapt quickly to changing circumstances. A pretty dynamic bunch!
