Completely agree with some of the comments, actually the hardest part is to execute these tests in a fast an reliable manner paralelizing the most of it, for your regression tests.

As we all know, in large orgs the form issue has been solved by using trusted components with unit tests. What worries me is how somebody were actually to provide valuable bugs, those that keep you up at night trying to fix them.

I worked with exploratory testing companies that would report hundreds of bug that nobody ever cared about. Does YC really care about the bug that they found, or have a business impact?
