Key person dependency
Key person dependency is a business's reliance on one individual — typically a founder, owner or senior expert — whose absence would materially damage operations, client relationships or company value. It is a standard flag in due diligence and business continuity assessments.
What is key person dependency?
The dependency has several strands: decision authority (nothing moves without him), relationships (clients buy from him, not the company), skills and licenses (only he may sign off), and knowledge (only he knows). Insurance can soften the financial blow ("key man insurance"), and delegation can spread authority — but the knowledge strand needs its own treatment, because knowledge is the one asset that cannot be reassigned by decree.
Not to be confused with knowledge concentration risk, which is precisely that knowledge strand viewed on its own.
Why it matters for SME continuity
In an SME the "key person" is usually obvious — everyone walks to the same office when it matters. What is less obvious is the timeline: the dependency grows silently for decades and must be unwound in the months around a retirement or sale. Buyers routinely discount valuations for it, which makes reducing it one of the few investments that pays at exit.
Key person dependency inside MentX
MentX addresses the knowledge strand: the guided capture turns the key person's knowledge into a company asset — a knowledge base in your own Knowledge Space — while the expert keeps veto rights over his profile. The dependency on his presence shrinks; the respect for his knowledge doesn't. The Founding Partner Program →
