I don't see revenue taking part in the discussion other than showing you have a true business model. Having a stable, profitable business model means you're a small business and not a startup.

I also tend to start calling a company with 30+ employees a small business rather than a startup. You can't support that many employees without being a stable profitable company (ideally I suppose).

Funding doesn't need to be able to support 30 people in order to be decent. What's decent depends on what the company needs.
