TopSource Announces CEO Transition; Co-Founder Guil Hastings Appointed Chief Executive Officer
London, 11/03/2026 — TopSource today announces that Ian Larkin will step down as Chief Executive Officer after three years in the role, having decided to pursue another opportunity. The Board thanks Ian for his leadership and contribution during an important period of development for the business.
Effective immediately, Guil Hastings will assume the role of Chief Executive Officer.
Guil was one of the original founders of TopSource and currently serves on the Board of Directors. He has remained closely involved in the company’s strategy, performance and long-term growth initiatives. His appointment reflects continuity in leadership and confidence in the company’s direction.
Doug Sawers, Chair of the Board, commented:
“Ian has led TopSource through a significant phase of growth and operational development. On behalf of the Board, I would like to thank him for his contribution and wish him every success in the future. We are delighted to appoint Guil as CEO. As a founder and active Board member, he brings deep knowledge of the business and a long-term commitment to its continued success.”
Guil Hastings said:
“TopSource has always been a business built on strong client relationships and long-term partnerships. Having remained closely involved at Board level, I am excited to step into the CEO role and build on the strong foundations in place. There is no change to our strategic priorities, and we remain focused on delivering exceptional service to our clients and driving sustainable growth.”
TopSource continues to benefit from the support of Horizon Capital, its majority shareholder.
Ian Larkin commented:
“It has been a privilege to lead TopSource over the past three years during a period of meaningful growth and development for the business. I am proud of what we have achieved together and grateful to our people, clients and partners for their trust and support. With Guil stepping into the CEO role, the company benefits from founder leadership and deep continuity. This transition presents an opportunity to further sharpen our focus on our customers and continue building on the strong foundations already in place. I look forward to seeing TopSource continue to thrive in the years ahead.”
Tom Maizels, Partner at Horizon Capital, commented:
“We thank Ian for his leadership over the past three years and wish him well in his next chapter. We are fully supportive of Guil’s appointment. As founder and Board member, he is uniquely positioned to lead TopSource through its next phase of growth, and we remain confident in the company’s strategy and long-term prospects.”
