Our network

A foundation of data and trust

 

Our research combines source documents, fund data and analyst judgment. We record the fund and share class examined, the evidence date, the scope of the work and unresolved questions.

 

  • Operational review: Examine documented controls, service providers and relevant risks within the agreed scope. Record where evidence remains incomplete.
  • ESG Integrity: We partner with RIBI (Responsible Investment Brand Index) to audit the consistency between a manager’s corporate culture and their responsible investment claims.
  • Documented conclusions: Research records explain the findings, limitations and follow-up questions relevant to the fund decision.
