Praise be to Allah.
If the situation is as you describe, and the money does not go back to the person who donated it according to the proportion that he donated, but is now no longer owned by any one of them and is to be spent only for the purpose for which they donated it, then there is no zakaat due on it. And Allaah knows best.
