Paul Graham combines his background as both a computer scientist and painter to view great programmers as artists rather than engineers, which shapes how he evaluates founders as creative makers, and he co-founded Viaweb, one of the first web-based SaaS companies written in Lisp, giving him unusually deep experience with early internet software. He has become uniquely influential as a startup essayist, writing dozens of canonical essays like "How to Get Startup Ideas" and "Do Things that Don't Scale" that communicate his investment philosophy, and he turns his observations from Y Combinator founders into generalizable principles through this distinctive feedback loop between investing, observing, and publishing.
