I started my career at a company that was entirely bootstrapped, and by the time I left, they were doing nine figure annual revenue. Since then I've worked at VC-backed startups (all of which have actually generated revenue). The longer I think about it, the more I think that bootstrapping at the beginning is the right move, and then to see how far you can go while bootstrapping. Raising money should be on the table, and will often be the right decision, but the longer you can go without raising it, the better position you'll have put the business in to succeed after raising.
