Robert Allen has had more students become self-made millionaires than any other person I’ve ever heard of. I’m sure people have failed who have done his program (and they probably blame him) but that’s the same with anything because you have to do it not just sign up.
I don’t know anyone else who can claim that their students have reported making $1.2B.

Prosper, Inc. is his “results-based education” partner. I found page where he talks about why he partners with them: http://www.prospering.com/partners/robert_allen.php
Robert Allen seems to me like one of those people who has proven that his stuff works. If you’re ready to take the leap into creating your own income, Robert Allen and Prosper are probably going to be a lot of help based on the results.
