This reminded me that OKC used to blog about results and data a lot. Before they got bought by Match it really did seem like they had some interest in matching people. But it is also crazy now that of the 3 main apps (Tinder, Bumble, Hinge), Match owns 2 (Tinder and Hinge). The unfortunate part of all this is that network effects are essential to dating apps working, so it is hard to enter the space.
