ZenPayroll CTO here. At least for the stage that we're currently in, having high unit test coverage, high-level integration tests, a strong code-review process, and individual accountability for bugs has worked very well for us so far. So well, in fact, that we don't feel we need a dedicated QA team. It's also worth mentioning that when coming up with our values/principles, we started with the understanding they can and probably will change over time, especially as we grow. So while we don't have dedicated QA team today, we'll keep an open mind do whatever works best for us in the future.
