Looking For A Comprehensive Sector Categorisation (string) For A Boolean Search On Company Name

Hi,

I’ve got a large list (1M+) of company names which have input by users. I’d like to categorise them by sector, but given the regional bias of some sets (e.g. SIC, NAICS) and the cost of others (Bloomberg) there isn’t a single comprehensive source that I can find.

Does anyone know of one? The end output is career guidance for people getting back into main street work (e.g. mums after kids, veterans leaving the forces).

​

Thanks
