We do the hard work

  • We’ve screened over 20,000 charities for strong governance.  
  • We screen these charities by annual revenue, years in operation, charitable status, and more. 
  • We’ve scored hundreds of the best charities by impact, scalability, networks and co-benefits 
  • We perform further due diligence on operations, financial statements, governance documents, etc. 
  • We’ve admitted the highest scoring charities in six sectors to our Portfolio. 
  • We produce detailed Impact Reports.
  • We re-score our Portfolio every six months.  
  • We replace organisations if we find stronger-performing charities.
