Owner dependency

88/100
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 "FISH" — strong identity link between founder and business.
  • +Founder age: Director aged approximately 72 — succession pressure is live.

Succession & seller-readiness

79/100
Likely off-market candidate

Strong acquirability signals converging. Worth approaching directly — this is how off-market deals start.

SIGNALS
  • primaryFounder aged 70+: Senior director is approximately 72 years old. Natural succession window is now.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondary12+ year tenure: Director in role 14 years.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
