Owner dependency

78/100
High — earn-out structure required

Material founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.

FACTORS
  • +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
  • +Founder name in company name: Company name contains director surname "SIMPSON" — strong identity link between founder and business.
  • +No director turnover: Company is 5 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

36/100
Weak signal

Limited succession signal. Not a near-term off-market candidate.

SIGNALS
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.

Red flags

clean
No red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
