Magnet 360 has a powerful attraction to clients, including 3M, Cargill, and General Mills. The Golden Valley agency, which provides marketing strategy and related IT services, made Inc. magazine's list of the country's 500 fastest-growing companies. Founders Litman and Mallin opened Magnet 360 in 2008 by partnering with a variety of small agencies that each provide a specific service. A couple of years ago, it combined a few of those agencies into one business. Magnet 360 now employs 74 people, and has offices in New York, Chicago, and San Francisco. It also raised several million in new equity to fuel more growth.
