Heather’s early career was shaped by entrepreneurship and resilience. In 2008 she launched TopLine Comms, an agency she built during the global financial crisis. Despite challenging conditions, she grew TopLine into an award-winning international agency serving hundreds of clients, from global giants like Samsung, Shell and the University of Cambridge to high-growth tech start-ups such as Xero and Sonovate. Over 13 years she employed more than 100 people and helped position her clients for remarkable growth stories. During this time, Heather also discovered her love of mergers and acquisitions, completing the company’s first deal in 2018 and eventually selling TopLine to Definition in 2021. These early experiences gave her a sharp understanding of leadership, innovation, and the realities of building successful businesses from the ground up.

After the sale, Heather joined the Definition leadership team, first as Marketing Director before becoming CEO. In this period, the company grew achieved over 200% growth in less than 3 years. Under her leadership the agency expanded to more than 100 staff across three offices and launched Definition AI, a pioneering technology arm. The business climbed into the PR Week Top 150 Consultancies and worked with clients including Amazon, HSBC, Lego and Transport for London. Heather then chose to focus entirely on the future of AI, investing over 2,000 hours in studying data science, governance, ethics and practical applications. This led her to take on the role of Advisory Board Chair at EXUS and to found One Somebody Limited, helping entrepreneurs achieve successful business exits.
