Friendfinder and their brands are run by Andrew Conru. They're quite successful; they own Penthouse. At one point he tried to buy Playboy, but Hefner wouldn't sell. They don't really have 300,000,000 accounts; there's been litigation over their fake accounts. It's probably going to turn out to be like Ashley Madison, where over 95% of the female accounts were fake.
They had a breach last year, but it wasn't as big.[1]
