Maybe you could say a bit more about why you’re asking. In some cases others would be right to suggest that you find material relevant to business for yourself.

The one case that I can think of off the top of my head that might apply to this situation is if there are disagreements re:product refinement/feature set/bug prevalence. (Basically, “why doesn’t this work as seamlessly as X?”) In that case you might do well to find the MVPs (and later iterations) of famous startups.
