Yes you can submit a proposal to different FIWARE accelerators, if it seems to fit with the addressed objectives of the accelerators. However, the same application must not be submitted to more than 3 FIWARE Accelerators. On top of that, the applicant needs to state that in the case of being accepted for funding by one of the FIWARE Accelerators, he/she will immediately notify the other Accelerators with whom it applied with the same proposal. On top of that, the applicant needs to state that he/she will NOT accept any funding or financing aid of more than one FIWARE Acceleratorfor the same proposal.
This shall assure that effort can only be reimbursed once. The submitted applications to the 16 accelerators will also be cross checked to identify any redundant proposals.
