You shall use results of the Future Internet programme that were developed before. The basic intention is to test, improve and promote the wide uptake of those results to achieve a critical mass of commercial adoption. In the FInish accelerator we are furthermore promoting the use of the FIspace platform, which is one of the FIWARE technologies. Moreover, there is the FIWARE catalogue that offers additional software (http://catalogue.fi-ware.org/).
For being eligible to ask for a sub-grant you need to use FIWARE results. Without this usage your pro-posal cannot be considered for funding.
