Work on all clients, including the other wins - Motley Fool, Equifax and The Higher Education Academy - is set to begin immediately. The assignments vary from formulating clients' overall internet strategy, to driving increased website revenue through consumer and business insights.
Matthew Pitt, managing partner at Generator, said: "The online marketplace is actually oversupplied with companies offering a myriad of disciplines. It's rather confusing for marketers. By offering everything in one place that a client needs to drive their business online, we seem to have pressed the right button."
Motley Fool is a personal finance site, Equifax is a credit reference agency and The Higher Education Academy offers online support for higher education institutions.
Motley Fool marketing director Emma Davies said her company "didn't just want usability advice", but wanted a consultancy that had a track record of "creating clear-cut new revenues".
Generator was established as a specialist division within I-Level in 2001, but then became an independent firm. It is run by chairman Charlie Dobres, managing partners Pitt and Jeremy Swinfen-Green. However, it is currently searching for a managing director. The consultancy works with a mixture of private and public sector businesses, including Bradford & Bingley, GCap Media, the AA, RAF, BSkyB, Gillette and Orange.
