Many leaders point to community-grown solutions as more trusted, sustainable, and embedded in local realities than top-down approaches. But few examples show what it takes to move those solutions into the mainstream or how public systems can scale them without diluting what made them effective. One exception is village savings and loan associations (VSLAs), or savings groups. By embedding savings groups in national development plans and systems, governments lend them legitimacy and long-term backing. But what if public systems could scale community-led solutions not by absorbing or reshaping them, but by recognizing their value and investing in the conditions that help them grow?
