note: i have little experience with startups, this is just a placeholder for me to write up some of my notes as i learn
note: some people design 'startup' as a business designed to grow really fast (implying that taking outside funding is almost always necessary, and excluding 'lifestyle businesses'). I don't define it that narrowly here, although in this book i am focused on 'tech startups' more than, say, a dry-cleaners.
