He leads FIL Platforms, which delivers the capabilities that enable Fidelity International’s global business across Asset Management, Distribution and Group Functions. His remit is to improve how FIL executes for clients, enabling faster, more consistent delivery of client and investment outcomes, with clearer prioritisation, stronger accountability, and reduced duplication across the organisation.

Earlier, he led Technology and Enterprise Services through a period of significant digital transformation. This combination of client, business, technology and operational leadership shapes his focus on simplifying delivery, strengthening accountability, and building capabilities that scale across the organisation. 

He is a strong advocate for inclusive leadership and building diverse, empowered teams. Stuart serves on FIL’s global DE&I Council, chairs its Early Careers programme, and was the first executive sponsor for Social Mobility at FIL. In 2026, he joins the Advisory Council of Inclusion in Finance (IiF), contributing to industry dialogue on financial services and inclusion.
