After graduating, Coyle and her family moved to Botswana, where she worked in small business development. After returning to Canada, Coyle completed her master's degree, before moving to Indonesia to work as a rural development advisor. Her master's paper on small-scale businesses attracted the attention of Calmeadow, a microfinance firm; Coyle was approached to design a program for Indigenous peoples in Canada, resulting in the establishment of The First People’s Fund, which provides microfinance loans to First Nation and Métis communities, and helped create BancoSol in Bolivia, the world's first commercial microfinance bank.
