In fact, my hunch would be that most are started with personal savings and family money.
I think it'd be a much less attractive choice if you were in an area like tech where you do have the option of a well-paying job or funding, though. Lifestyle businesses are still attractive in tech, but only if you're somewhat better off, either coming from a better-off family, having already had one minor success on a previous business, or spending some time in a lucrative job / consulting career that let you save up a cash reserve. That appears to have been Steve Blank's route as well; he became a self-funding entrepreneur only after first having a few successful exits from funded companies.
"personal savings and family money" - sba loan, mortgage the house, credit cards, equity line to name a few more.
