The challenges Big Finance and Big Technology bring to social finance must be faced, and the opportunities they offer seized, if their potential to scale social impacts are to be realized. The previous chapters describe these challenges and opportunities, as well as a leadership approach that can help channel the power of ‘Big’ into doing good. Using case studies of the UBS Optimus Foundation and the Future-Fit Foundation (FFF), this chapter returns our attention to how Big Finance can leverage change for positive social and environmental outcomes. In the case of the former, social finance and technology tools are being used to help the poor and enslaved. In the case of FFF, the influence of the financial sector is being deployed to build a regenerative economy in line with the SDGs. In both examples, the context, the tools and outcomes, and the Deliberate Leadership each brought to bear are detailed.
