The practice

Senior expertise, without the institutional overhead.

Johannes Horstmann, founder of J Advisory

J ADVISORY (Pty) Ltd offers financial modelling, financial structuring, capital raising support, financial close process management and hedging process management to project developers, investors and banks in project finance transactions.

Every mandate is led personally by a senior adviser with close to twenty years on infrastructure transactions — from bid strategy through lender negotiation to financial close and into asset management. The result is faster answers in the room, and a model the lenders trust.

  • RobustNo broken formulas, no cell overwrites, far fewer human errors.
