The field of innovation for social purposes is developing rapidly all over the world, with new institutions and methods, growing confidence and evidence of impact. Social innovators are changing the way governments work, the way civil society achieves impact, and the actions of business. The field combines commitment, experience and energy. But it lacks the systematic and sophisticated infrastructures of support available to other fields – in particular access to appropriate finance and funding. The result is that although there is no shortage of good ideas, far too few achieve the impact they could. The report sets out a vision for where we want to be ten years from now. It highlights how these various infrastructural gaps will need to be overcome in order for the field to develop to maturity and puts forward recommendations for how we can achieve this.
