Owner dependency

55/100
Moderate — manageable with handover

Some founder dependency, but not acute. A structured handover period should cover most risk.

FACTORS
  • +Young company: Only 1.7 years old — management layer unlikely to be developed.

Succession & seller-readiness

30/100
Weak signal

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

Red flags

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