Why risky: No growth signal; thin margin for error on price.

What this business does
Primary activity: Management consultancy activities other than financial management
Sector: Professional, scientific & technical
Investor take
Pursue
Strong opportunity: active trading company with strong profile and bankable structure.

Opportunity 75/100 (strong), bankability 75/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. Biggest value-creation lever: Broaden director team. Sole director creates succession risk and reduces buyer comfort. Appoint a second director or strong #2. Most likely exit: share sale to pe / searcher (58/100).

Data confidence

Overall: medium (78/100)

Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency

85/100
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
  • +Sole director: Only one active director — all governance concentrated on one person.
  • +Long-tenure founder: Senior director has been in place 17 years — deep operational knowledge concentrated in one person.

Succession & seller-readiness

68/100
Strong succession signal

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

SIGNALS
  • primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
  • secondary12+ year tenure: Director in role 17 years.
  • secondaryStable-but-static management: Company is 21 years old and no new directors in the last 3 years — succession not yet being planned internally.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
