Midas – Enriched contact information for email lists

This is good, but still falls into the FullContact/Intercom/Clearbit camp without clear differentiation. The service would add a lot more value if it niched down and provided really relevant information. As a sales person, I haven't found a service that actually tells me what I want to know about a lead/company. I often find myself wanting to know some combination of the following:

# of employees, approximate revenues, years in business, family-owned or not, number of locations, age of founder(s), scope(s) of work.

This helps me form a mental image of the company and helps me decide whether or not its worth pursuing them.

How is this different from Clearbit's Enrichment API?

How can I trust this service (and others like it) to keep the list of email addresses I provide confidential?

Another spammer to block. Is there a way to identify email processed through this system?
