There are massive network effects, employers only sign up to learn information from other companies, and give up their own information as a condition for the former. It's a business that bootstraps when you have an existing customer base of related services, dealing with employee and payroll management, credit ratings etc. and mine your existing data for a prototype product good enough until the network effects kick in. Maybe you could make it bootstrap by making it very cheap or free, so that, even if employers don't usually get anything from you, they still remained enrolled for the rare instance when you deliver something that others lack, so that you can buildup your database in time. But then highly secure, easy to use and long term come at odds with free.
