Stagwell is working to build an investment portfolio of marketing services companies. We are putting digital first in all investments without being weighed down by legacy assets. Our portfolio will only have one or two of each kind of agency from: digital media buying to market research to public relations and beyond to allow for true cooperation. Most importantly, we know great talent needs to be valued and nurtured to achieve best in class growth that will allow for generous incentives and financial rewards. To facilitate that growth, we will act as value added investors, not simply managers, through new business development, strategic counsel and add-on acquisitions that keep agencies on the cutting edge of marketing innovation.
