Two grant-making bodies have pooled their international development funding so they can distribute more grants.
The John Ellerman Foundation has teamed up with the Baring Foundation to increase the latter's £500,000 international development fund to £650,000.
Both hope the pilot project will lead to more collaboration by grant-making bodies in the sector.
Tim Glass, director of the Ellerman Foundation, said: "Our foundations share a lot of common interest overseas. If it goes well, we'll look for others to join us."
The additional Ellerman money will assist projects in Africa, in line with its traditional aid to the region, while the Baring fund will continue to aid projects in both Africa and Latin America.
The Ellerman Foundation will also continue its separate overseas programmes, which have previously funded medical health and social welfare projects for Africa Now, VSO and WaterAid.
