The Subcontracting and Partnerships Exchange, or Bourse de Sous-Traitance et de Partenariats (BSTP) in its original name, is a platform that connects local businesses looking for a market with foreign companies operating in the mining, processing industries, infrastructure, construction, banking, insurance and other sectors.

The BSTP is a non-profit organization whose members come from the Government, the Guinean private sector, and socio-professional organizations. It is initiated by the Ministry of Mines and Geology with technical and financial support from the International Finance Corporation (IFC) of the World Bank Group.
