Figuring out what a startup should say to investors is strangely useful for figuring out what it should actually do. Most people treat these questions as separate, but ideally they converge. If you can cook up a plausible plan to become huge, you should go ahead and do it.

For example, I'm always looking for ways to add network effects to a startup's idea. Investors love those. But network effects are genuinely good to have. So any we come up with in order to feed to investors, they should probably go and make happen.
