Over the years, I’ve worked with teams that involve QA from the very beginning — and others that bring QA in right before launch.
Both can work depending on context.
I’m curious — when does QA enter your process?
Good framing. For the YC list, I'd pick sites where the hero names the category but not the product, because that is where positioning beats layout. Curious whether the fix you land on most is copy or visuals.
