I realize HN thinks startups are sexy, but these have no business being labeled startups. If Intuit is a startup, what does it take to be a called a mature company? ------- 2 decades after the IPO should be the cutoff point. After that, you're "mature"; before that, you're still considered a 'scrappy startup' which might fold at any moment without the day to day pivoting of the charismatic founders in their garage. ;)
