Not GP, but in a similar position. No, no concern whatsoever. The owners are not greedy which makes all the difference in the world. Not that the profit is low - it is probably much higher this way, when the whole company pulls toward the goals. I have never worked in an environment with so low amount of office politics.
With the way things look right now for high-tech (or any software development) companies the margins are quite high. But of course, if you are a VC who invests in hundreds of businesses, and expect only a few of them to fly, then those few must fly pretty high to make it worth your while. Which means that being just very profitable is not enough - you need to be extremely profitable. And that comes with compromises (mostly for the workers at such startups).
