The Ithaca Team

Alaric Mostyn

Organisational Design

Management and strategy consultants often sell Organisational Design services to major organisations but their big brand names guarantee a ‘one size fits all’ approach which seldom works for Corporate Affairs and IR. And when they intervene, do they really help the organisation to absorb their advice and new structures so that it becomes owned by the business? Rarely.

Alaric Mostyn has worked with Corporate Affairs functions for more than 35 years and is the global expert on how to help organisations work out what they need from the function, how to structure it best to get that, and how to measure whether that is what they are getting once the new structure is in place. There is no one better in the market.


  • Alaric has held senior consulting and corporate leadership roles at Oliver Wyman, PwC, Young & Rubicam, Wolff Olins and the BBC.
  • He founded and runs Stonecourt & Co, working with leadership teams to change their organisations for the better, with productive cultures and improved performance – including deep experience in how to make the most of corporate affairs.
  • Stonecourt is a long-term collaborator with Ithaca Partners.
