We are nearing the end of this course. By now, you have identified a global challenge that you would like to address, found the right customer segment, mapped your environment, and dived deeper in business cultures and management styles. The last step in this course will focus on the impact you can have with your idea or startup.

In this lecture, Esther discusses how to invent a good revenue model for your idea. Next, in the interview video, the entrepreneurs you met in the first modules address their contribution to global challenges and the impact they make.
