The PME Leader status is a seal of reputation created by IAPMEI (Institute for the Support of Small and Medium-Size Enterprises) to distinguish national small and medium-size enterprises for their superior performances. It is granted in partnership with Turismo de Portugal (in case of companies in the tourism sector), a group of partner banks and Mutual Guarantee Societies. It is based on the notions of rating and economic and financial indicators.

A PME Leader has access to a number of benefits, such as special conditions to financial products and a network of services, as well as bank facilitation and the prestige associated with the PME Leader brand in their relationship with stakeholders.
