Focus statement

  • Team of experienced operators: managing £5bn+ AUM with track record of scaling successful businesses and executed 5+ exits
  • First-of-A-Kind (FOAK) financing approach for infrastructure and real assets, backing platforms early with calculated risk
  • Access to enterprise clients for growth underwriting through established relationships
