Most founders assume that what got them to $100m will get them to $1B. It won't.
I've seen this pattern play out at both Uber and Revolut. The early days reward speed, instinct, and a small team that moves faster than the market can react. But somewhere around the $500m–$1B mark, the game changes completely. The skills that made you successful — tight loops, founder-led decisions, scrappy execution — start working against you.
What actually changes: the cost of a bad hire compounds faster. At 20 people, a wrong call costs you three months. At 2,000, it costs you a division. Decision quality matters more than decision speed. Process stops being bureaucracy and starts being leverage.
What stays the same: the best operators I've worked with never stopped thinking like founders. They kept the urgency. They stayed close to the customer. They didn't let organisational complexity become an excuse for distance from reality.
The transition is hard because it requires you to evolve your identity, not just your tactics. The founders who navigate it best are the ones who hire people smarter than them early — and then actually get out of their way.
