What this is: a dated directory of companies publicly associated with UK early-stage investment portfolios. Membership is a research snapshot dated 2026-03-31, not proof of current ownership, tax qualification, investment availability or performance. Company status is refreshed separately. Six source records currently have no exact mapped company and are retained as noindex coverage notes.
Comparison
See where portfolios overlap
Shared companies can reveal co-investment patterns and explain why two fund portfolios move together. The comparison report maps repeated company numbers without turning them into a performance ranking.
A newer portfolio will usually show a higher raw active rate. The survival report compares companies against others incorporated in the same year before drawing a conclusion.
Start with coverage and identity: the same trading name can refer to different legal entities, so CompanyBeacon keys every mapped company to its Companies House number. Then check the membership source date, current company status and the age of each portfolio. Do not use company counts or active rates as a substitute for fees, mandate, eligibility, valuation, realised returns or professional advice.
