Harmon Recruits Marta Sierra from the “Non-Bank” to Join the “Non-Market” as Director of Corporate Communications

Harmon, Spain’s first consultancy specialising in non-market strategies, has appointed Marta Sierra as Director of Corporate Communications, with the aim of continuing to attract top industry talent as part of its growth strategy.

A journalism graduate from the Complutense University of Madrid and holder of a master’s degree in Communication Management and Advertising from ESIC, Marta brings 15 years of experience in corporate and financial communications. She joins Harmon from her role as Head of External Communications at ING, where she led the bank’s external positioning.

With this appointment, Harmon strengthens its professional advisory capabilities in non-market strategy. Following the recent acquisition of the financial communication consultancy Comco and its partnership with the Portuguese firm Generator, the company continues to accelerate its growth, now consolidating a team of 80 professionals as it enters its third year of operation.
