London Mayor Boris Johnson spoke to a crowd of 80 clients and staff at the official opening of M's new global head office in Isleworth, West London yesterday (8 October).
The creative, marketing and events agency moved from its former offices in Ealing in July, following a raft of new business wins, including the NATO Summit, which it delivered in Cardiff last month.
It also announced the launch of Resonance, a new consultancy brand that will be led by Daniel Ritterband, a former director of marketing for the Mayor of London, who joined the agency in June.
Resonance will sit under the M Group umbrella, alongside six other creative brands including Voice, Amigo, Sportcel and PJF.
Managing director Jim Curley said: "We outgrew our previous offices and decided to relocate to Old Isleworth to help the business to continue to grow. In 2013 we saw 15% growth and I think we can maintain double-digit growth this year as we have had our busiest year yet."
Speaking at the event, Johnson said: "Astonishing things are happening at all points of London’s compass and M will bring incredible creativity, as well as some of the finest minds in marketing and communications, to Isleworth. Their new office is opening during a time of extraordinary growth in our city and they will be well placed to capitalise on the wealth of economic opportunity that should offer."
British Airways, BAE Systems, Royal Navy, Delta and Ernst & Young are on M's client list.
