If you’re curious, the point of the startup was to path-find between you and people you want to be connected to but aren’t (investors, say), telling you which friends-of-friends to prioritize getting to know in order to later leverage them as intermediate links in the chain to meet the people you really want to meet, that are three or four or five steps removed from you, and so entirely invisible to your local part of the network.
(And yes, that’s a really darn cynical play. But the data that we did have showed that the intermediate “links” in your chain would almost always be business-people, “growth hackers”, etc. for whom getting to know you was valuable in its own right—they would value any chance to grow their Rolodex. So it at least seemed like a positive-sum interaction on the surface.)
On the surface, it sounds useful, but also like Tinder, would've likely been abused.
