What Does an Interim CEO/COO Do?

Companies occasionally face situations where a highly experienced top-level leader is needed at short notice. Whether it’s the sudden departure of a managing director, an unexpected corporate crisis, or a phase of rapid growth, in these moments, an Interim CEO or COO can be the decisive solution. This temporary executive steps in to lead the company or its operations, providing stability until a permanent appointment is made.

Definition: Interim CEO/COO

An Interim CEO (Chief Executive Officer) or Interim COO (Chief Operating Officer) is a highly experienced top executive who temporarily assumes leadership of a company or oversees its operational management. Interim CEOs and COOs bring many years of senior leadership experience and can steer an organisation confidently through challenging phases such as restructuring, rapid expansion, or transitional periods. Their responsibilities also include strategic realignment, leadership under pressure, and bridging leadership gaps at the top. They are ready to start immediately and, thanks to their broad experience, can make critical decisions and implement necessary measures without lengthy onboarding.

Typical Scenarios for Interim CEOs/COOs

Interim leaders at C-level are primarily deployed in exceptional situations where swift, competent management is required. Typical scenarios include:

Corporate crises: In moments of acute crisis — such as liquidity issues, dramatic revenue decline, or structural problems — an Interim CEO acts as a crisis leader. They stabilise the organisation, develop immediate measures, and initiate turnaround programmes.

Succession challenges: When a CEO suddenly leaves or a generational transition is underway, a leadership gap often emerges. An Interim CEO bridges this vacancy, keeps the company on track, and prepares the successor for a smooth takeover.

Rapid growth phases: Fast expansion — for example, through entering new markets or rising demand — requires solid structures and processes. An Interim COO with strong scaling experience ensures operational stability, implements efficient processes, and manages growth sustainably.

M&A integrations: Following mergers or acquisitions, different cultures, systems, and teams must be brought together. An Interim CEO or COO can act as a neutral facilitator who drives integration, aligns teams, and reduces friction.

Leadership and Stability During Transitions

Interim Executives stand out for their strong leadership skills and adaptability. During transition periods, they provide the stability needed to reassure employees, customers, and investors.They make clear, fact-based decisions — including difficult ones — and ensure uninterrupted business operations. While the Interim CEO sets and communicates a clear strategic direction, the Interim COO ensures this direction is executed effectively. Thanks to their authority and experience, Interim Executives quickly gain acceptance across the organisation — keeping the company fully operational and preparing it for the future.

Advantages for Companies

Engaging an Interim CEO or COO provides several advantages in challenging situations:

• Maximum flexibility: They are contracted for a limited period and only for as long as needed.

• Deep expertise: They draw on extensive leadership experience and have often successfully managed similar situations.

• Fast impact: With minimal onboarding and a strong results focus, they tackle urgent issues immediately — saving valuable time compared to permanent hiring processes.

Why Interim Executives Are Particularly Effective in Switzerland

In Switzerland — shaped by many SMEs and highly specialised global players — Interim CEOs and COOs can create significant impact.SMEs benefit from access to top-tier management expertise that is not always available in-house. Since losing a single leader can be critical in such structures, an Interim Executive quickly closes leadership gaps. Many Swiss companies are also active internationally. Internationalisation requires experience with different markets, cultures, and regulations — something Interim Executives often bring with them. Additionally, many family businesses face generational transitions. Here, an external Interim CEO can act as a bridge, ensuring stability while the internal succession is prepared.
