The problem

Marketers and agencies are miles apart.

78%
of marketers think their briefs give clear strategic direction
5%
of agencies agree

That gap gets expensive.

33%

of marketing budgets are estimated to be wasted through poor briefs and misdirected work. That's more than €370 billion worldwide every year.*
