How do you know they don't? Mojang Specifications, this year's hottest new game studio, uses Scrum. The Lean Startup movement combines customer discovery with Agile practices. That said, my experience is that development practices have little to do with startup success (unless they're overly rigid or formal, in which case they get in the way of success). They affect organizational scalability and long-term maintenance costs, which fall in the category of "nice problems to have" for a new startup. I do see ideological blinders here, but not the ones you meant.
