London – June 27, 2025 – Brown Advisory, an independent investment and strategic advisory firm committed to delivering exceptional outcomes for its clients, is pleased to confirm that it is in advanced conversations with London-based Marylebone Partners LLP (“Marylebone Partners”) to build a leading endowment-style offering for clients based outside of the U.S. The plan will bring together two firms with a shared commitment to client values, the pursuit of investment excellence, and long-term partnership.
Marylebone Partners was co-founded by CIO Dan Higgins in 2013 and is trusted by families, charities, endowments, and trusts to grow and protect their wealth. The firm is recognised for its ability to identify differentiated investment opportunities, sourced through a global ideas network built over nearly three decades.
The move will enhance Brown Advisory’s existing capabilities by providing a greater range of investment opportunities and strategies to meet the developing needs of clients. Specifically, it will:
- Provide distinctive and complementary return sources including hard-to-access independently managed funds, co-investment opportunities and direct investments, enhancing the return potential of client portfolios.
- Strengthen Brown Advisory’s investment team by adding one of London’s most respected allocators with three decades of experience investing in fundamental strategies, including alternatives. Marylebone Partners will bring with it an extensive database, proprietary investment and risk analytics, and sophisticated portfolio construction tools.
- Enable the clients of Marylebone Partners to benefit from Brown Advisory’s extensive global resources, infrastructure, and in-house investment expertise.
- Allow the Marylebone Partners investment team to focus on sourcing and managing high-return potential, differentiated investments for their clients.
- Provide Marylebone Partners’ clients with access to Brown Advisory’s leading direct equity and fixed income strategies.
Marylebone Partners’ team will remain responsible for the management of its client portfolios, which should immediately benefit from being part of Brown Advisory. Marylebone Partners is expected to continue as the investment manager of Majedie Investments PLC, an investment trust with a ‘liquid endowment’ strategy.
Upon completion of the transaction – which is subject to regulatory approval – Marylebone Partners’ principals will convert their ownership interests into Brown Advisory’s equity.
Logie Fitzwilliams, Co-CEO of Brown Advisory, added: “We have long admired Marylebone Partners’ thoughtful approach and investment expertise. We are always looking to improve and build our service for clients, by offering a broader range of investment opportunities and strategies that meet their bespoke needs. With the Marylebone Partners team onboard, this will enhance our ability to serve endowment, family, and trust clients with an increasingly differentiated investment platform. I am thrilled to welcome them to Brown Advisory.”
Dan Higgins, Co-Founder, Partner, and Chief Investment Officer of Marylebone Partners, commented:
“I have known and respected the team at Brown Advisory for more than a decade, and we will be proud to become part of their success story. The current environment presents some of the most compelling investment opportunities we have seen since founding the firm and, working within Brown Advisory, we will be able to take full advantage. Our clients’ portfolios will continue to be managed by the team they know, with our capabilities enhanced by greater investment resources, research and expertise. Brown Advisory’s partnership model, client-first culture and commitment to the highest level of service, align with Marylebone Partners values. We have committed for the long-term, and I am very excited to join forces.”
