Rebecca Fox is the Founder and CIO/CTO of Relentica, helping ambitious organisations turn technology strategy into commercial growth, stronger performance and reduced risk. A two-time CIO 100 UK award winner and a Northern Power Women Game Changer, she brings more than 20 years of executive technology, transformation and operational leadership.

Rebecca has led global teams and complex change across cyber security, AI, automation, data, cloud, digital platforms and operating models. As Group CIO of a FTSE 250 cyber and technology business, she worked across four continents, led a team of 190 and delivered cost optimisation, platform consolidation and organisational change. Her earlier work included directing a £100m-plus technology portfolio supporting 60,000 users and stabilising technology operations.

Through Relentica, Rebecca works with CEOs, boards, investors and technology leaders who need leadership without necessarily appointing a full-time executive. She provides fractional CIO and CTO leadership, technology and data strategy, transformation assurance, AI adoption, cyber resilience, cost optimisation and support through investment, acquisition and exit.

Her approach connects strategy with disciplined delivery. Rebecca simplifies complex decisions, challenges assumptions and builds the leadership, governance and delivery structures needed to create measurable business value. She is also a keynote speaker, event host and executive roundtable chair.
