Industry Classification - Industry property - Use a standard
I understand that the industrial property in Hubspot is used to buy industry insights but I am surprised at the mixture of different classification types there are.
Why not NAICS Code Directory and map old classifications to the right group. Just as you guys have multiple levels lead source you could do the same for NAICS classifications up the hierarchy. Considering how important customer segmentation is to effective marketing. I'm really surprised and a little disappointed it such a mixture of things... or use the Bloomberg classification - Sector, Industry, Sub Industry. But use a standard... or if it's your own then create a hierarchy and share it with everyone maybe showing how different standards map to your classifications. You could share in a spreadsheet or create an article on your blog about it :-)
