Fast growth is exhilarating. It is also unforgiving.
Especially in AI, many companies are seeing hyper-growth, changing the leadership job faster than many founder-CEOs expected. What once required deep personal involvement suddenly demands scale and breadth. The question for leadership is how to adapt without losing the mission, or the magic, that made the company take off in the first place.
Having worked closely with founder and non-founder CEOs at every stage, I see the same patterns repeated whenever organizations grow faster than leadership roles evolve. The strengths that make founders extraordinary early on can become constraints if they are not deliberate about how they lead as the company grows.
Here are three leadership shifts that matter most as companies move from liftoff to orbit.
1. Focus founder attention on what only they can do.
The CEO role in a large organization typically has a broad scope, with responsibilities ranging from setting strategy to aligning talent, capital, culture, and external relationships.
In mature companies, CEOs manage the full remit by spreading their time to juggle it all. However, founder-CEOs are often different. They tend to be spiky in their strengths: exceptional product intuition, deep engineering judgment, or a visceral connection to the mission. Those strengths are not incidental. They are why the company exists.
The best founder-CEOs do not abandon or dull their strengths and quirks. Many continue to focus on their distinctive gifts rather than becoming “generalist leaders”. They stay focused on the areas where they are gifted but they must do it at a different altitude. The risk comes when they stay too close to execution in the areas they love most. Reviewing every design decision, diving into technical debates, or rewriting product specs can feel like leadership. Over time, however, this approach crowds out what only the CEO can do: setting direction, placing big bets, and building the leadership bench.
Instead, great founder-CEOs make their thinking legible and repeatable by others. When teams understand a founder’s mental model, such as how trade-offs are weighed, and what will not be compromised, decisions move faster without waiting for direct involvement.
2. Design a shared leadership model.
If founders concentrate on what they do best, the rest of the typical CEO responsibilities must be covered deliberately by others.
In practice, this often means a shared leadership model. While these can be problematic in traditional companies, they have proven powerful in founder-led firms. Many iconic companies pair a founder-CEO with an operating leader, whether a co-CEO, president, or similar role, with clearly differentiated mandates. Founders often focus on product, engineering, and mission, while partners take primary responsibility for mobilizing the organization, running operations, and managing external stakeholders.
Titles are less important than design. What matters is clarity, alignment, and solidarity. Two conditions are essential. First, there must be a unified direction and voice. Disagreements are inevitable, but they must be resolved at the top and behind closed doors, not played out across the organization. Second, people need to know who decides what. Without that clarity, teams test seams, escalate selectively, or shop for a different answer.
When designed well, shared leadership increases speed rather than slowing things down.
3. Make leaders operate as an enterprise team.
Even with the right leadership model, execution does not take care of itself.
One of the least discussed fragilities in fast-growing companies is that much of the leadership team is suddenly in the biggest job of their lives at the same time, and those jobs are expanding as fast as the company itself.
That reality calls for judgment, not heroics. One stabilizer is to seed the team with a few leaders who already have experience in companies a few stages ahead of where the company is now. They can anticipate what is coming and have the pattern recognition to know where companies tend to break and which issues require attention when.
Equally important is to shift how leaders operate. As companies grow, leadership teams must move from functional excellence to enterprise leadership. Leaders who were once rewarded for optimizing within their own domains now need to know how to weigh second- and third-order effects and make trade-offs for the whole. When teams do not make this shift, decisions stall, escalate, or fragment. Momentum slows. The CEO becomes the default integrator and, ultimately, the bottleneck. The differentiator between good and great leadership teams is rarely brilliance. It is discipline: the ability to think beyond silos, decide together, and move forward with coherence.
Leaders operating in a period of rapid growth face the same question: are they evolving how they lead, or relying on the instincts that worked when the company was smaller? The answer will determine not just how fast the rocket travels, but how far it can go.
