Tinder isn't a real startup, but a manufactured success for a couple of well-connected douchebags (who behave as if they're above the law). It's the Disneypreneur phenomenon (http://michaelochurch.wordpress.com/2014/06/09/silicon-valle...). If you look into it, both of these guys are invaders from the MBA culture.
These phony startups, that are actually pre-arranged by powerful players in the mainstream corporate/McKinsey world, are becoming a lot more common and they're often difficult for genuine, old-style startups to compete with. (They blow up big, suck up a lot of talent and attention, then fail and lose credibility, so their inferior capability still leads to a both-lose outcome.)
This is going to blow up big in a couple of years: this massive proliferation of propped-up junk businesses and pseudo-startups run by incompetents. We're already seeing the embarrassing-but-not-yet-devastating fuckups. We haven't seen an Enron yet. But that's going to come, and it's going to have massive effects (and probably negative ones, on good and bad players) on the startup scene.
