Yeah, let's see if we can list some companies that already do that...
Credit card companies, depending on our credit score, give us...
- discounts on interest rates, money transfers (not useful to us since we never maintain a balance, but still)
- free unlimited travel via hotel/airfare with credit card hacking (super useful to mustachians)
- access to more cards with no annual fee and better cash back
Banks give us lower interest rates on loans depending on credit score.
Car insurance companies rate us on our driving history and price us accordingly.
Life insurance companies do a health report, and price our insurance based on when they think we're most likely to die.
Tennis clubs will often give extra time/benefits to their top junior players, because they know that other juniors will train wherever the "good kids" train. I assume this is true for many sport/music oriented businesses.
