I funded my first business with credit cards, and it worked out very well. Many if not most small businesses get funded to some degree in that way.
And I’ve used credit in my business. Was charging about $15k a month to American Express mostly for travel and business expenses. Then a customer billing went from $300k a month to $0k because a vendor screwed me. All of a sudden Amex was telling me not to make my house payment or feed my kids so I could pay them. Got them paid and have learned to do business without them.
