What's "the NFP space"? I googled but all I find is random local clubs and companies called NFP, none of which look like powerful lobby clubs.
Try the likes of the Hans Wilsdorf Foundation, the beneficial owners of Rolex who operate under the guise of a charity.
There is no requirement to disclose financial or charitable donations under law, and the company pays no corporate taxes as a result of being owned by the Foundation.
Not for profit.
Covers full charities, and other legal statuses like public beneficials etc.
NFP = Not For Profit
People usually call i t NGO for non-government organisation. Not For Profit is just another euphemism. In casual conversation people usually say nonprofit. Or if they feel fancy, a 501.c3 nonprofit. In the US. Not sure how these work in other countries.
