Heidi Whitfield, G3 managing director, relishes her role. ‘I spend much of my time with our senior advisers, which is both a privilege and a crucial point of differentiation. They are all leaders in their fields and provide access for clients that isn’t available to everyone.’ A former corporate lawyer before discovering that her ‘strong analytical skills, interest in international politics and natural manner with clients were perfectly suited to the business intelligence sector’, she highlights G3’s ability to provide ‘sensitive, difficult-to-access information’, thanks to the team’s background in intelligence — and the ‘knowledge and connections’ of their ten-strong board of senior advisers, including the former senior partners of Slaughter & May and Herbert Smith Freehills, Tim Clark and Lord David Gold, Richard Reid, Lord Paddy Ashdown, Sir David Scholey and Sir Peter Bonfield. ‘Our clients really appreciate our private briefings and discrete gatherings with ambassadors and former country leaders. Senior adviser Paddy Ashdown is reliable for incisive political insight and has been particularly valued over the last 12 months.’ It’s a factor that sets G3 apart, she says: ‘We are able to provide discrete human intelligence.’ Whitfield spends time in Berlin, Geneva, Moscow and Zurich: G3’s Berlin office is headed by Dr August Hanning.
