This is just the same spam you get at any startup. The “scam” is they are just information brokers, not venture capitalists. To give you the “valuation” they ask for a bunch of inside knowledge about your operation and employees, which they sell to the various “startup tracker” websites. And the dark web if you give them enough info. They’ll be like “we need to do background checks on you and your employees for our potential investors” and ask for W2 records and SSN and bank deposit info, etc.
