Empresas Públicas de Medellín (EPM) is a utility company offering energy and water services based in Medellín, Colombia. EPM's clients often have outdated, inefficient home appliances, or lack access to these in the first place.

Furthermore, many of the company's clients are excluded from formal credit lines that could enable them to access to better appliances. In 2008, the company launched an inclusive business program, Financiación Social, aimed at offering micro credit loans to its low income customers.

The offering is based on the unique credit score EPM obtains from clients' payment records on their utility bills. EPM had issued 100,000 cards by autumn 2012, with the goal of expanding the program to 500,000 clients in 2016.
