A pattern I have lived through more than once, and watched many of my peers live through, is the moment when a growing organization quietly stops feeling like the one you started with.
The all-hands lands differently. Decisions take a little longer. New hires describe the company in ways that don't quite match what the early team would say. Nobody has done anything wrong. The culture is just no longer doing what it used to do on its own.
I've sat through this transition at many different scales. From small early-stage teams, through the messy middle stages where things grow faster than the operating model, all the way up to large global organizations. Each stage has its own version of this moment. The shape changes, the symptoms change, but the underlying question is the same. The way the team works has outgrown the way it was originally set up to work.
In that moment, the natural instinct, certainly mine and many of my peers', is to reach for the familiar tools. Write down the values again. Run a culture workshop. Hire a Head of Culture. None of that is misplaced; it is often necessary. But in my experience, it has rarely been sufficient on its own. The deeper issue, when I look back at the transitions I've lived through, was usually that the culture was built for a different scale, and the operating layer underneath it hadn't been redesigned to match where the organization was now.
The way I've come to think about it is this. Culture at scale behaves like an operating system. The kernel, your non-negotiable values, stays fixed. The shell, how ownership, decisions, and processes actually work, needs to be rewritten at every growth stage. Organizations seem to struggle when they freeze the shell instead of evolving it.
A note on the evidence
This is not only a metaphor. There is well-known research from anthropologist Robin Dunbar showing that humans can maintain only a limited number of stable relationships before group cohesion starts to strain, which is why some companies, like W.L. Gore, deliberately cap facility sizes and build new ones rather than letting existing ones grow further. Patty McCord, Netflix's former chief talent officer, has written that the conversations she has with CEOs about cultural transitions repeat themselves at almost every growth stage. The fracture isn't a failure of values. It is a structural transition that asks the leader to redesign the operating layer.
Underneath all of this is something I learned the hard way. Clarity from leadership, visibility in decision-making, and helping people see the bigger picture isn't a project. It is a continuous job. I've done it reactively, after an incident made it obvious. I've done it by stepping into someone else's shoes when I should have done so earlier. And I've done it because I was lost once myself, and that probably taught me more empathy than any framework could.
The cultures I've seen scale well aren't the ones with the best values posters. They are the ones where leaders keep the kernel sacred, keep redesigning the shell, and keep processes accountable to outcomes, rather than the reverse.
