Building a New Futures

If you're building a product that's going to eventually need to have users pay for it, the first stage of growth is optimization. You want to know what features are most important and how many people will use them at any given point in time. And then when you've got more than one million users, start thinking about your next step: How do we make this even better? The key is getting good leading indicators such as user reviews or net promoter scores.
