27 April 2026: London – GBST and AJ Bell have announced a new 10-year deal, reinforcing their long‑standing technology partnership and setting out a clear roadmap for the continued evolution of AJ Bell’s advised and direct to consumer (D2C) platform.
Under the agreement, the global technology provider’s Composer wealth administration platform will continue to support AJ Bell’s advised and D2C channels as the platform continues to grow.
As AJ Bell continues to operate at scale, managing total assets under administration of £109 billion across 723,000 advised and D2C customers1, the long-term extension enables the continued provision of a modern, resilient operating model designed to support long‑term growth across both advised and direct‑to‑consumer channels.
AJ Bell has seen strong growth in recent years, driven by its clear customer proposition, competitive pricing and reputation for high-quality service among both financial advisers and investors. GBST’s Composer platform underpins key operational capabilities across AJ Bell’s advised and D2C channels, helping to meet the needs of its increasing customer base while maintaining high levels of service.
Michael Summersgill, CEO of AJ Bell, said: “GBST has been a key technology partner for many years, supporting the development of both our advised and D2C propositions. This long-term partnership reflects the strength of our relationship and our confidence in GBST’s ability to help us scale and innovate, enabling our business to continue to grow.”
Rob DeDominicis, CEO of GBST, said: “AJ Bell is one of the UK’s leading investment platforms and we are proud to support its future growth through our Composer technology. Investment platforms play a central role in the UK wealth market and the technology that underpins them must adapt as adviser and investor expectations change. Our continued investment in the Composer platform, cloud-based delivery, and emerging AI‑enabled capabilities allows firms like AJ Bell to benefit from modern, scalable technology that enables long-term growth, operational resilience, and improved decision-making while maintaining the reliability advisers and investors expect. We look forward to working closely with AJ Bell as its platform business continues to scale.”
David Simpson, Head of EMEA at GBST, adds: “The long-term extension to our relationship with AJ Bell highlights our close collaboration and shared innovation, built over 15 years. During this period, the platform has grown significantly and our underlying technology has continued to evolve to meet the changing needs of investors and advisers. The next stage of our partnership will provide AJ Bell with the benefits of a modern operating model, making it even easier to extend functionality and support the continued expansion of its adviser and D2C channels.”
