Monster, the online recruitment company, is seeking an agency to handle its pan-European advertising account.
A shortlist of undisclosed agencies has been compiled to pitch for the business, worth an estimated £20 million across Europe. An appointment is expected by the end of July.
The move comes as part of a centralisation process by the company, which will see it handle marketing on a regional, rather than market-by-market, basis.
The pitch will be handled by AAR and overseen by Eric Sabbah, the director of advertising and media at Monster.
The UK incumbent, Leo Burnett, is to repitch for the account. The agency has held Monster's UK above-the-line and digital business on a project basis for just 18 months, having won it from Saatchi & Saatchi in 2005.
A spokesman for the company said: "Monster has been a phenomenal success globally. With our advertising, different geographic regions may require different approaches, and we are, therefore, looking to appoint an agency that will help us bring the Monster proposition to life in as compelling a way as possible to our diverse audiences.
"We've been working with a number of agencies over the past year, but we're now looking to establish a relationship with a single agency," he added.
