I'm curious: does the term "bootstrapped" apply only to how you begin the business, or to the entire history? I tend to read it that way, but I can see where others might disagree.

Where do you draw the line? I think everyone starts with something of their own before getting investor money, eg: clothes, a computer, travel expenses. What's the cutoff? $100? $1000? etc

We've bootstrapped Stormpulse for years. Even if we take outside investment, I will still acknowledge our start as bootstrapped. At that point we would no longer be "bootstrapping" though.
