The concept is simple: your PI score makes you eligible for different discounts. Presumably, higher scores will qualify you for larger discounts.
The discounts aren’t tailored to you, they’re offered based on your overall PI score. The hope is that you’ll find something you’ll like, that the discount will be sufficient for you to tell your friends and that your friends value your opinion.
This is influencer marketing on a broad scale. People aren’t being segmented by interest; the only contextual information is your overall PI score. Scale is key for this product to be a success, however, one thing that can be guaranteed is that as with every business that relies on volume, it will not impress the purists.
