Alternative asset management firm Duet Group, through the creation of Duet Consumer West Africa Holdings (DCWA), has invested US$50 million to take controlling stakes in two Ghana-based companies: Shop N Save, a supermarket joint-venture with the founders of raw and processed agri-commodities distributor Finatrade Group, and GNFoods, a food manufacturing company. The new funding for these two companies will be used to roll-out new food retail stores, expand manufacturing capacity and invest in sales and marketing capabilities.
