As far as I know, Fiinovation is one of the best CSR Consultancies in India. There are many friends of mine who have availed services of Fiinovation and have always praised for its professionalism and work ethics.
In fact, as many people do not know, CSR is a very vast field and any corporate who wants to perform a CSR activity, has to look after many aspects like Grant Management, Grant Facilotation, Detailed Project Assessment Report, NGO Assessment, NGO Funding, On-ground Activation, Porject Assessment Reports, etc. And above all of them they will have to deal with local authorities.
