You’re also adding qualitatively different kinds of people to the team. One metaphor I use to explain this shift is to take yet another analogy from military history: the marines take the beach, the army takes the country, and the police govern the country. Marines are start-up people who are used to dealing with chaos and improvising solutions on the spot. Army soldiers are scale-up people, who know how to rapidly seize and secure territory once your forces make it off the beach. And police officers are stability people, whose job is to sustain rather than disrupt. The marines and the army can usually work together, and the army and the police can usually work together, but the marines and the police rarely work well together. As you blitzscale, you may need to find new beaches for your marines to take rather than ask them to help patrol the existing ones.
