Valuation · August 2026
Every buyer asks a version of the same question during diligence: what happens to this business the day after the owner stops showing up?
Valuation professionals routinely apply a formal 10–25% key person discount to a business that depends too heavily on one individual.
If the honest answer is "it struggles," a buyer won't just lower the price — some will walk away entirely, because they're not confident there's a business there to buy, just a job the owner happens to own.
The most rigorously documented figure here comes from valuation theory, not deal anecdotes: Shannon Pratt, one of the field's most cited authorities on private-company valuation, and other appraisers commonly apply a key person discount of 10–25% to a business that's meaningfully dependent on one individual. That's a formal adjustment appraisers make when they value a company, not a claim about what any specific business will sell for.
Separately — and this is looser, more anecdotal evidence — M&A advisors and brokers who work these deals regularly describe founder-dependent businesses closing at noticeably lower multiples than comparable businesses that don't need their owner day-to-day. The exact size of that gap varies a lot by source, which is why the formal 10–25% discount is the number worth anchoring on if you want something defensible.
None of this is fixed with a memo. It's fixed by spending one to three years, well before a sale, systematically moving each item above out of your head and into the company: assigning a second point of contact on every major account, writing down the pricing and vendor logic that currently lives only with you, building a management layer that can run meetings and close deals without you present, and — the hardest one — actually stepping back far enough to prove the business holds up without you.
The takeaway
Owners often treat this as a personality trait ("I just like being hands-on") rather than what it is on a balance sheet: a discount a buyer will apply whether you acknowledge it or not. It's one of the few value drivers almost entirely within an owner's control, given enough runway before a sale.
