Different? We’re worlds apart

MASECO was founded on the belief that great wealth management knows no borders or boundaries. As pioneers and practitioners of tailored strategies for US, UK and global families, we’re motivated not by how many assets we manage, but how many lives we enrich.

A service as unique as your needs

Our expertise comes from an unparalleled position of first-hand experience and real understanding.

Why MASECO?

We aspire to provide an exceptional service. But we are so much more than a wealth manager. We are a trusted partner, adviser, and friend to our US, UK and global client families.

Pioneering thinkers

In 2008, our founders believed that there was a better way to serve the needs of high-net worth and ultra-high net worth US families living overseas.

Today, we stand at the nexus of analytical research and immersive wealth planning – bringing vast international experience, unique investment insight and the broadest network of specialists to our US, UK and global client families’ lives.

Life Partners

Your goals guide everything we do. We understand that navigating your wealth the way you want takes more than a plan – it requires a partner. We specialise in creating deep, fiduciary relationships where our clear investment pathway and unique evidence-driven approach provides the clarity and reassurance you need to focus on the journey ahead.

UK/US focused and tailored to your distinct multi-jurisdictional needs, our powerful three-step program – Best of All Worlds™ – plans and maps a clear, data-driven pathway.

Data devotees

Backed by over 15 years of multi-jurisdictional financial expertise, comprehensive quantitative and qualitative analysis drives MASECO’s methodology. Data underpins our academic approach to systematically active investing – leveraging returns while managing risk – delivering a researched, systematic approach implemented consistently across asset classes and the globe.

We’re proud of our culture

We work with trust, transparency and openness. We believe that when your life is guided by a sound plan, you can achieve great things.

With your goals as our guide, our commitment to always do what’s right for our clients sets us apart.

  • We know that phenomenal client service and enduring success lies in having a strong culture and outstanding employees who live our values.

    In a fast-moving and increasingly complex global financial landscape, our success depends on how adeptly we adapt, but equally, how faithfully we adhere to our core values. To act with integrity and responsibility at all times, while supporting the growth of our US, UK and global client families.

  • Over the last fifteen years we have listened to, and worked with, thousands of families to enable them to make choices on how they can live their best life. We have gathered that data and experience and created a three-part program to help our families live a rich and thriving life.

    We call it: Best of All Worlds™.

  • MASECO’s mission is to make a difference. We operate on the guiding principle that the future of wealth management is intrinsically linked to a sustainable future for all.
