I've seen a handful of cases where a small software house with very limited name recognition that provides some genuine value to customers gets a big bump from advertising targeted to "lookalike audiences" on facebook. Some of these shops run either 0 or 1 ad campaigns at any time, so the correlation is actually visible and quite irrefutable.

However, that is also the exact type of adtech that is extremely dodgy in terms of privacy, because it thirsts for data. I'd love the whole thing to end in favor of some genuine user recommendation system. But as always, any ranking system that drives revenue will be gamed to no end.
