Primary activity: Technical testing and analysis
Sector: Professional, scientific & technical
Investor take
PursueStrong opportunity: active trading company with strong profile and acceptable with review structure.
Opportunity 71/100 (strong), bankability 65/100. High owner-dependency — earn-out structure likely required for clean transition. Share purchase looks the cleaner deal structure. Most likely exit: share sale to pe / searcher (58/100).
Data confidence
Overall: low (54/100)Sparse data coverage. Treat AI-generated outputs as preliminary. Manual diligence essential.

Owner dependency
71/100
High — earn-out structure requiredMaterial founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
- +Young company: Only 0.2 years old — management layer unlikely to be developed.
Succession & seller-readiness
36/100
Weak signalLimited succession signal. Not a near-term off-market candidate.
SIGNALS
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
Red flags
cleanNo red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
