Organizations don’t just grown on their own. You build them, and you may end up building multiple organizations, each one atop the previous one. The scale-up logic is straightforward: You present what you did (the past) to motivate where you will go (the future), but what you work on is the middle (the present). Most emerging organizations fail because they build for the future having ignored the entire present. But you don’t have to worry about whether a decision is optimal for that rosy future—it just needs to work today. As you build the next organization, you’ll reuse parts from the old one and you’ll get to implement everything you’ve learned. Growth and scale-up work like problem solving: no one cares how you first came up with the solution. The organization that systematizes your current innovation prototype is your first big milestone.
