It's not something most people should do, but if you're in a pinch it might be a lot better than diluting & dealing with the hassles of bringing in more angels. I don't think you're giving enough credit (no pun intended) to credit card companies willing to give you 0% interest for 6 months to a year.

But to your point, it's very risky and NOT something most people should even consider. There's no way in hell I'd sell my soul to a credit card company at 20% APR either.

I have never bootstrapped a company on a CC. Fortunately this latest endeavor is all about micro-transactions so we're cash-flow positive very quickly. If I bootstrapped on a CC, I would never exceed a debt level more than the value of personal assets (car, equipment, etc..). Always plan an exit...
