Owner dependency

86/100
Critical — business is the founder

The 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 "BLACK" — strong identity link between founder and business.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
  • +No director turnover: Company is 13 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

49/100
Moderate signal

Some succession indicators present. Worth watching; approach if sector/strategy fits.

SIGNALS
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondary12+ year tenure: Director in role 13 years.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
