William Blair Investment Management is a global asset management firm based in Chicago with resources in New York, London, Zurich, Sydney, Stockholm, The Hague, Singapore,* and dedicated coverage in Canada. Our investment teams employ disciplined, analytical, research processes across a wide range of strategies, including U.S. equity and non-U.S. equity, fixed income, multi-asset, and alternatives.
We work closely with consultants, private and public pension funds, insurance companies, endowments, foundations, sovereign wealth funds, and financial advisors.
And, we are committed to active management. Our equity investment teams believe markets are inefficient at differentiating between average and quality growth companies—meaning bottom-up research is required to identify companies with strong long-term potential.
