Good point. Also worth comparing startups to regular SMBs, who don't do national TV advertising but rather focus on local listings, niche magazines and outdoor. There is a tool for every marketing job, which for a startup might mean sponsoring a meetup of early adopters, then releasing some shwag, doing PR or advertorials, and ending in harvesting demand via search. Otherwise, when you perceive advertising as a hammer, everything starts looking like a nail.
