When a Startup Becomes a Company: Three Critical Turning Points in Leadership

Many growth companies encounter their first significant leadership challenges when growth is already in full swing. The organisation has scaled rapidly, new talent has joined, and business operations have become more complex. Meanwhile, leadership models have often remained stuck in the initial start-up phase.

While growth challenges are often discussed from the perspective of finance, strategy, or the market, in practice, one of the key bottlenecks is leadership and organisational structure. Leadership methods that work for a ten-person team no longer function in an organisation of fifty or a hundred employees. Many companies perform excellently in the early stages but face unexpected challenges precisely as growth accelerates. The cause is usually not a poor strategy, but rather the fact that the company is transitioning into a new stage of development.

During growth, three recurring leadership turning points require new ways of thinking from both management and HR:

1. From Founder-Led to Shared Leadership

In a start-up’s early days, decisions are made quickly. The founder or a small core group knows the business inside out and can react agilely to changing situations. However, as the company grows, this approach can easily begin to slow the organisation down. With more employees, every decision can no longer pass through a single person.

The first major leadership turning point is the transition from a founder-led model to shared leadership. In practice, this requires three concrete shifts:

• Responsibility is genuinely transferred to other leaders.
• Decision-making is decentralized throughout the organisation.
• Roles, responsibilities, and leadership models are made transparent.

For many growth companies, this phase is difficult because it requires founders to relinquish some control. At the same time, the organisation must learn a new logic of leadership: not all important decisions are made in the same room any more.

2. The Culture Testing Phase

In the beginning, corporate culture arises largely on its own around the founders. A small team works closely together, and common practices take shape through day-to-day life. With growth, the culture is put to its first real test. New employees are no longer part of the company’s origin story, and the organisation splits into multiple teams.

At this stage, many growth companies notice that communication begins to fragment, teams make decisions in different ways, and company values easily become abstract. If the culture is not articulated and led consciously at this point, the organisation will gradually begin to develop several parallel ways of operating. This is reflected, for example, in decision-making, co-operation, and how people perceive the company’s direction.

3. The First HR Crisis

Many growth companies view HR as a support function for a long time. This works well initially because the organisation is small and informal. However, as growth continues, people management becomes a strategic issue. A typical turning point occurs when the company faces its first broader personnel-related challenge.

Often, this takes the form of an employment law situation. For instance, a rapidly growing company may find that a leader recruited in haste does not fit the organisation, or that the role no longer matches the company’s next growth phase. The situation can escalate quickly: should the role be changed, can the person be moved to another position, or is it a matter of terminating the employment?

In such a moment, leadership, corporate culture, and employment law become intertwined. For many growth companies, the situation is surprisingly taxing because it is only then that they realise personnel matters can no longer be resolved solely informally. At this stage, many companies recognise that HR management is no longer just recruitment or administration. It begins to directly affect the company’s ability to grow and execute its strategy. Often, it is at this point that HR shifts from a support role to becoming part of the core business operations.

Leadership Changes as a Company Grows

One key challenge in managing a growth company is recognising when the organisation is moving to the next stage. Often, problems do not stem from strategy or the market, but from the fact that the leadership model does not evolve with the company.

As a start-up grows into a larger company, the focus of leadership shifts from individuals to structures: clarity in decision-making, management team operations, and the more conscious development of organisational culture. The founder’s role changes from specialist to leader of people, and leadership capability becomes a critical factor.
