I would bet people are staying on over 50% given the acceptance rate and self selection there, but that's 12M in revenue even at 100% active paying and 10% acceptance rate.

That's 200K per employee - server costs. Seems like they're likely near break even, but even if not, they aren't burning a ton is my bet. VC's would be head over heels for that audience for even just a whiff of influence or monetization being dangled in the future.
