How does Honey make money, aside from the obvious data collection? I know a few people who use it, and I've cautioned them in the past that I can't think of any savory business model that would make this profitable. Is there one? Is it just tracking purchases for advertisers, or is there some other monetization strategy I'm missing? Their main site says they make commissions, but I don't know how to square that with…
From what I've heard they don't actually sell purchase data. I don't know for sure though.
I don't understand how referrals are worth 4b though.
