Ranking Europe’s top business CIOs

Clare Simmons — October 2013

Who are the most powerful CIOs in Europe? We identify the individuals who manage the greatest challenges at the Continent’s biggest companies — and spend up to €2-3bn a year in the process.

Most European economies may still be faltering, but the region’s largest companies continue to ride high in the global revenue charts. And critical to sustaining their competitive positions, in an increasingly digital business environment, is the leadership that defines and guides their IT strategies.

As the only publication focused on global CIOs, I-CIO profiles below the top 20 enterprise CIOs in Europe (based on their organization’s last reported annual revenues).

CIOs from three sectors — energy, automobiles and financial services — dominate the table, with the geographical spread centered on Europe’s most buoyant economy. In fact, CIOs from German companies take a quarter of the places in the top 20, followed by CIOs at French and Italian companies with 20% each of the slots.

Notwithstanding the supra-national nature of such companies, only six of the CIOs listed are from outside their organization’s homeland. Americas Alan Matula and Mike Gibbs, at Shell and BP respectively, are notable exceptions to the rule, as is Tesco’s Irish-born Mike McNamara, Enel’s Rafael López Rueda, originally from Spain, German Dirk Marzluf at Axa and Glencore Xstrata’s French CIO Cyril Reol.

Whatever their origin, these are by far the most powerful IT executives in European technology — with stratospheric annual IT budgets to match. One shared with us how he had cut the annual IT budget by a quarter in recent years, leaving him with just €1.7 billion ($2.3bn) to spend.
