Keith Weed, chief marketing and communications officer, Unilever

Weed may not do much brand-centric marketing these days, but he’s certainly very active marketing Unilever, and has been a constant presence on conference platforms over the past year. His pitch about sustainability is important, and one he delivers with conviction. Mobile is another hot topic you’ll probably hear his views on, too. The smartly starched Weed is arbiter of best marketing practice at one of the world’s biggest brand owners, and it doesn’t get much better than that
