Personally, I'm sad that this model seems to not pan out. I'm a successful bootcamp story - I graduated from App Academy about 7 years ago and have been working as software engineer since. My closest friends were all successful and all work at companies that you've heard of. The ISA model was key to me enrolling as I was skeptical of bootcamps. I was happy to pay if it worked about, but wanted to hedge my bet in case I enrolled in one of the many of the unscrupulous bootcamps that didn't actually teach anything.

In my case, I found AppAcademy really helpful because I had a set of engaged peers, I had access to TAs to help answer questions, and the material was solid. However, from what I've gathered, a lot of the industry moved away from teaching this way in order to scale their classes and make more $$. Videos have replaced live instruction, class sizes have increased, and they let anyone TA classes. I wonder if most of the failures of ISAs are due to the poor product these companies are offering vs the issues with ISAs themselves.
