Senior marketers from Aviva, Barclaycard, Virgin Media, Diageo and Mars are speaking at the one-day event.
Topics covered will range from social media and data to the marketing director of the future.
The conference will be chaired by Piers North, Yahoo! UK's strategy director. North has been at Yahoo! for more than seven years; he previously worked at Rivals Digital Media and 365 Group in sports publishing.
In July Yahoo! hired Google senior executive Marissa Mayer as its president and chief executive.
Insiders say Mayer is focusing the company on its technology credentials, in particular on its advertising platforms and products such as Yahoo! Mail and Flickr.
