Then you look up and the room has gone quiet. The higher you climb, the fewer people are positioned to challenge your thinking, stress-test a call before it becomes a commitment, or tell you that the read you are proud of is actually a blind spot. Development flows downward, and at the top it thins to almost nothing.

I have watched the value of that missing room the long way around. Over the past few years, former OpenAI leaders have gone on to build Anthropic, xAI, Safe Superintelligence, and more, different companies drawn from one origin. Whatever else that environment held, it produced people who could think at the frontier and then go do it on their own.

The environment built that capability through pressure, exposure, and rooms full of peers who had no reason to defer. Most senior operators had exactly that on the way up. Past a certain altitude they lose it, and they rarely notice until a decision they were certain about goes sideways.

I felt this most acutely after I left my corporate roles in 2021. Inside a large company the structure hides the gap. There is always a review, a skip-level, a board that pushes back. Step outside it, or climb high enough inside it, and the pushback quietly disappears.

For the first time the quality of my decisions rested entirely on the quality of the thinking I brought to them, with no system left to catch a weak one. The irony was not lost on me. I had spent two decades making sure the leaders under me never had to decide alone, and I had quietly stopped arranging the same thing for myself.

What I lacked was a room of peers operating at my level with no reason to agree with me, and no volume of information substitutes for that.

That absence is quiet and expensive. A leader without real challenge does not feel themselves getting duller. The decisions still get made and the organization still moves. The judgment simply stops being tested, and untested judgment is where senior careers plateau without ever announcing it.

You can see it in how leaders handle their biggest bets. The ones still being sharpened argue with someone real before they commit. The ones who are not have started arguing only with themselves, which always feels like rigor and rarely is. From the outside the two look identical for a while. Then a market shifts, and only one of them adjusts in time.

So turn the OpenAI question on yourself. If your best people left tomorrow, they would go build things partly because of the sharpening they got working near you. What is sharpening you right now? Who in your world has both the standing and the incentive to tell you your certainty is misplaced, and would you actually hear it if they did?

For most senior leaders the honest answer is no one. That is the room I built the C-Suite forum to be: a small group of peers at your altitude, no deference, real pressure on real decisions before those decisions harden into commitments you have to live with.

Someone in that room has run the re-org you are about to run. Someone has already made the AI bet you are hedging on. They have no stake in flattering you and every reason to show you where your thinking is thin.

If you have spent your career developing everyone but yourself, this is where that changes: join the room.
