Does this mean you don't consider 37signals a startup?

I would agree to no, they are not. They are a leader in their niche (simple small business products) and they are profitable beyond their original investment.

I can't recall how magazine publications refer to them (as a startup or a company based out of Chicago)

37signals is no longer a startup, its a lifestyle business

Just being picky but - I think 37signals is a "bootstrap" and not a startup.
