What this business does
Primary activity: Research and experimental development on biotechnology
Sector: Professional, scientific & technical
Investor take
Pursue
Active trading company with a 71-year-old founder — textbook succession opportunity.

Opportunity 78/100 (strong), bankability 75/100. Strong seller-intent signal (68/100, director aged 71). 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 (73/100).

Data confidence

Overall: medium (78/100)

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

Owner dependency

90/100
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.
  • +Founder age: Director aged approximately 71 — succession pressure is live.

Succession & seller-readiness

80/100
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 71 years old. Natural succession window is now.
  • primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.

Red flags
