Key-Person Risk: Could You Replace Your CXO in 90 Days?

Here is a simple test every board and CEO should run on themselves: if any one of your critical leaders left tomorrow, could you replace them — credibly — within 90 days? For most companies, the honest answer is no. That gap is key-person risk, and it is one of the most consequential exposures few companies actively manage.

What key-person risk is Key-person risk exists wherever too much depends on one individual: their knowledge, their relationships, their decisions, their relationships with customers or investors. If that person is irreplaceable in the short term, the company is carrying an undiagnosed, uninsured exposure.

Why it hides Key-person risk is invisible while the person is present and performing. Everything works, so no one asks the uncomfortable question. It only becomes visible at the worst possible moment — when the person resigns, is poached, or is suddenly unavailable.

Where it concentrates - Founders and CEOs — Especially in founder-led businesses where the founder holds the key relationships. - Rainmakers — Individuals who carry disproportionate revenue or client relationships. - Irreplaceable specialists — Deep technical or institutional knowledge held by one person.

How to manage it - Identify — Name your key-person dependencies honestly. This belongs on the board's leadership-risk agenda. - Reduce — Distribute knowledge and relationships; document what lives only in one head. - Prepare — Build succession options and know your external search options before you need them.

The 90-day test as a habit Run the 90-day test annually for every critical role. Where the answer is "no", you have found a risk worth managing before it becomes a crisis.
