I agree that cash flow positive is are not evil words to hear.

Still directionally this article is accurate. If an investor (even a seed investor) gets any whiff of "lifestyle buisness" out of you, they will RUN. And cash flow positive is a bad: it indicates that you dont have use for money which could grow faster, or you just don't value growing faster. Still I agree if you said your core business was cash flow postive, but then new investments were going to fund ones crazy growth, then that is a very sellable message. (and lends evidence that the underlying business is sound.)
