Owner dependency
81/100
Critical — business is the founderThe business appears inseparable from the founder. Acquisition without a serious earn-out or meaningful transition period would likely destroy value.
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 "ARMSTRONG" — strong identity link between founder and business.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
Succession & seller-readiness
36/100
Weak signalLimited 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
cleanNo red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
