That's why you need the original founders to make it again. OkCupid was a site made by 140 IQ dudes in Boston for 100+ IQ types. It was not an easy problem. It succeeded because the match % was uncannily accurate. Loss of the site (acquisition and tinderification by Match) was like the sack of Rome.
That said, I think the world has changed in ways that would make it difficult to replicate now. For one thing, imagine all the AI bot profiles that would exist. For another, the legal environment has only gotten worse in the sense that entities like Match will try to sue you for infringing on some bogus patent.
Also, let's not forget that the takeover by Match was a deliberate choice: those "140 IQ dudes" chose to sell out their nice product to a big evil company although it was pretty foreseeable they were going to ruin it. Who's to say that wouldn't happen again?
I married one of them and 2 of them are still close friends.
Sadly not very active or funded, right now.
That's why Tinder won. It's an easy way to filter out the unsexy.
I even tried to verify this by looking through old registries available online (where marriages and births were recorded), some of which are digitized and OCR'd by Yandex, but it seems that they do not have a list of unmarried people. Although the birth records typically mention whether a child is "legally born" (within a marriage) or not.

GP is correct. Human history spans hundreds of thousands of years. You are talking about the most recent ca. 5000 years of enforced monogamy through the social/cultural institution of marriage, but this era has come to an end and we are reverting to the natural state of affairs (polygyny) again.
