The Robert Wood Johnson Foundation wanted to pursue a new area of funding in which they did not have a great deal of experience. So, before releasing a Call for Proposals (CFP), Aggregate identified and engaged influencers who could help them reach new communities to inform their funding strategy and build trust for the foundation among those working in the field. Throughout the process, we served as the program officer’s coach, helping her build her online network and to share timely and transparent updates. The process contributed to establishing the program officer as a credible thought leader and led to new relationships and opportunities well before the CFP was released. When it was released, the CFP generated a level of interest unprecedented by past CFPs issued by the foundation.
