After the closure of each call, the FInish accelerator will evaluate the proposals with the help of external ex-perts. Finally, the proposals will be ranked and the sub-grant agreement (i.e. contract) needs to be signed by the FInish accelerator and the proposer. All this might require some 8-12 weeks. This means that you could start in Spring 2015 to develop an app, if you submit a proposal for the first open call.
