  • The IIMI strengthened by the appointment of seven new Board members

The Independent Investment Management Initiative (“IIMI”), a boutique asset management think tank whose membership accounts for approximately £500 billion in client assets, has appointed Sebastian Stewart as its Chairman as it embarks on the next phase of its development. The new, strengthened Board has significant and varied experience across the asset management sector, deepening the value that the IIMI can bring to its membership.

The new Board has refreshed its core aims, which are to:

  • Shape a regulatory environment that supports boutiques and promotes competition
  • Promote the strengths of boutiques and facilitate commercial opportunities for members
  • Drive best practice across the membership

Sebastian Stewart has been on the Board of the IIMI since 2017 and became Deputy Chairman in 2019.

It is as important as ever that we support the crucial role specialist asset management plays in the financial services sector in the UK and globally. I look forward to working with my colleagues on the Board to build on the excellent work of my predecessors while bringing fresh perspectives to the organisation. We are committed to supporting entrepreneurial specialist asset management firms, which are increasingly important in an industry dominated by global financial giants.”
