The NGLCC represents the interests of an estimated 800,000 to 1.4 million LGBT owned businesses. Through its network of 45 based chambers and business organizations as well as 9 internationally, the NGLCC is the largest LGBT business development and economic advocacy organization in the world.

In addition to many other programs and services designed to help LGBT and allied businesses succeed, the NGLCC is the exclusive national certifying body for LGBT owned and operated businesses. Supplier Diversity Initiative (SDI) is modeled after the National Minority Supplier Development Council (NMSDC) and the Women’s Business Enterprise National Council (WBENC), the national certifying bodies for ethnic minority and women-owned businesses, and their missions to create opportunities for minority owned businesses to gain development and procurement opportunities with major corporations.
