The Recurse Center[1] is the opposite of this. They don't take any of your income, they just help you find jobs and companies pay them to find cool people. And there is no curriculum. They believe that if people work on cool things they will learn a lot. I can't recommend it enough!
The "no curriculum" style automatically filters for a certain kind of self learning high achieving student. This is a reasonably guarantee of success and also limits the scale of the operation.
Lambda School is more of an attempt to train the average guy who wants to increase his earning ability. He doesn't have the time or patience to "work on cool things" in the hope of "learning a lot" which is loosely correlated to finding a good job.
They cater to different crowds and solve somewhat different problems.
+1 to this. I attended RC in winter of '18. It wasn't the best fit for my personal learning style, but it's an incredible program for the right person.
I highly, highly recommend it to anyone considering going there. Some of the kindest and smartest people you'll meet.
