At a demo day we had a meeting with a partner from a big fund and pitched him. He turned us down and told us why but was kind enough to have a follow-on meeting with us to talk further about our pitching strategy and general business strategy.
One of the key points I got out of speaking with him was this: VC's (institutional, not necessarily angels) generally want to see high-growth and not high-profit. If you've got revenue coming in and you're "profitable" on it, then you need to be growing more (spending it). To the point that most VC's believe you should grow so fast that you never reach profitability until you exit OR decide to "level out" the business.
