Owner dependency

94/100
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 "KEITH" — strong identity link between founder and business.
  • +Senior director age: Director aged approximately 58 — approaching natural succession window.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
  • +No director turnover: Company is 15 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

59/100
Strong succession signal

Multiple signals suggest succession is on the horizon. Candidate for proactive outreach.

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 58. Early succession window.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • secondary12+ year tenure: Director in role 15 years.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
