We describe many different finance tools in other sections which can contribute to systemic change. For investment funds to finance truly systemic ideas they need different methods to those used for investment in established systems. At an early stage there is unlikely to be any clear revenue model, or any benchmarks to draw on. Instead assessments need to include some judgement of the broader direction of change in the field as a whole; some judgement about the qualities of the key individuals; and some rough assessments of the relational capital they bring. Not surprisingly these tools and approaches are rare – and require a great deal of confidence in the funding agency as well as in those receiving funds.
