We explain Tinder’s early campus loop: Facebook-only signup reduced the first step to roughly 10 seconds, sorority parties supplied a concrete installation reason, fraternities added the other side of the network, and contract promoters later repeated the motion across campuses. A Turkey paid-market test was largely unsuccessful because paid users behaved differently from organic users. Source: [Original Tinder case](https://first1000.substack.com/p/tinder).
