My take on it: You can't find a date with your brain. It just doesn't work that way.
Speed dating works. It's more or less the only thing that does without a huge mountain of crap to sort through. Here's your /r/shittymilliondollaridea: Be the Uber of speed dating. Let people filter by either one or two variables. Age, height, credit score, cup size, educational level. But put strict limits on it so that people really are just getting themselves into the desired ballpark. Then, run a big matrix operation so that when 12 people of the appropriate genders have all matched, pop up a notification that they all have reservations at X restaurant / bar / whatever that weekend, and the ladies need to switch tables whenever their phone dings.
Best of both worlds, and you don't have to rent a venue.
