Thenetworkone aims to give independent agencies a "pick-and-choose" network to help them compete against the supergroups for international client work.
ELAN affiliate agencies include Alternative in France, BvH Groep in the Benelux, Kolle Rebbe in Germany and SCACS in Spain.
"ELAN is a mini-network that was going after clients in defined markets and we realised that there would be more opportunities if they joined us as part of a bigger group," Simon Tilden, the senior managing partner at theonenetwork, said. "The relationship gives our clients more choice of agencies in each European market and allows smaller agencies to compete with the big boys."
Theonenetwork has most recently worked with Vallance Carruthers Coleman Priest to provide it with network capability in France and Germany to help it win the AAR-run pitch for the delivery company FedEx.
The then-Butterfield Day Devito Hockney (now Partners BDDH) was a UK founding partner of ELAN, but ceased involvement in the network after becoming part of Havas Advertising. Mustoes has also worked with ELAN, but stopped earlier this year after the Japanese holding company Hakuhodo took a 49 per cent stake.
In May, theonenetwork picked up its first major client when Esselte, the office supplies business, awarded its global ad and promotional account to the start-up.
