Who We Are

Treeline's founders started working in commercial web development in the mid-nineties working with iconic brands such as Kodak, Lever Faberge, Meyer Prestige, Silentnight, Channel 4 and others. But it was their award-winning work at former agency Moonfish with ActionAid, Amnesty International and WWF that drove them to start an agency dedicated to charities in 2002. Since then they have campaigned, fundraised, persuaded, educated and recruited in partnership with an unrivaled worldwide client list including such names as ActionAid, ChildLine, Her Justice, Mines Advisory Group, AMREF and HelpAge International.
