I'm not associated with the company or product.

If you sell to a midmarket or enterprise customer base, they regularly need custom stuff.

eg group X of employees cannot see group 1 of customers' data. Or to use a more concrete example: US employees cannot see EU customer data because of GDPR. But it's never that simple: more fine grained, or with other exceptions.

This stuff took up way more eng time than I mentally budgeted; I could see a use case for a service.
