The amount of people involved in social innovation is rapidly increasing. Many people are trying to improve people’s lives and create more resilient and sustainable societies through innovation in social enterprises, innovation labs, grass root organisations, and within social and public-sector organisations. Many great examples exist of successful social innovation, as well as many failed initiatives. There is still a lot we need to learn about how we can advance this field and I believe that learning together and sharing knowledge is one of the keys to achieve this. In this blog I reflect on how we learn, and how we can learn from each other in social innovation, based on a one-month visit in May 2018 to the MaRS Solutions Lab in Toronto as International Fellow.
