William Blair is a global firm delivering sound, conflict-free advisory services to clients around the world. The firm has more than 1,100 employees and is based in Chicago, with office locations in 15 cities across four continents, including Boston, London, New York, San Francisco, São Paulo, Shanghai, and Zurich. This extensive global reach allows us to identify the optimal transaction partner for our clients regardless of location or language; more than one-third of our transactions are cross-border.

People. Our people are our greatest assets, and we have created an environment that attracts and rewards people who are passionate about delivering outstanding results for our clients. As an employee-owned partnership, we have created a collegial, supportive culture where senior professionals take a long-term view of the firm’s success and have an active interest in the development of their junior colleagues. We believe that rewarding our best performers—regardless of their title or tenure—is essential to the success of the firm. Compensation and promotions are determined by each employee’s track record of delivering outstanding results.

Growth. We have a mandate to help companies grow. Our clients rely on us from the time they are an emerging enterprise looking to gain access to capital until the time they become an industry leader looking to complete a transformative acquisition. We are committed to providing trusted guidance, industry expertise, and outstanding transaction execution every step of the way. We continue to expand our global footprint to provide enhanced local market knowledge to our clients. Since 2010, we have opened offices in Frankfurt and São Paulo and formed a strategic alliance with Business Development Asia.

Independence. William Blair has remained privately owned by active employees since the firm’s founding in 1935. This spirit of independence resonates throughout the firm. The stability provided by our diversified business model and strong balance sheet enables us to remain steadfastly focused on our clients’ objectives through all market conditions. We have a flat organizational structure that encourages collaboration and depends on employees at all levels to provide insight and new ideas.


Community Engagement. At William Blair, we are committed to serving our neighbors and being a long-term partner to the communities in which we live and work. Last year the William Blair Foundation contributed to more than 360 not-for-profit organizations, and each year our employees personally contribute to hundreds more through their time, money, and leadership. Each year William Blair forms strategic partnerships with several organizations that address the most pressing needs of our communities. Since 2011, our community partners have included the Greater Chicago Food Depository, Comer Children’s Hospital, and the By The Hand Club For Kids.


Future.  As our clients’ needs and the global financial marketplace evolve, we will continue to enhance our ability to deliver outstanding results for our clients. Across industries and geographies, we will continue to strengthen our expertise and presence in the areas that will provide the greatest growth opportunities for our clients. We know that our success depends on our ability to attract and develop people who are defined by their sharp intellect, uncompromising standards, and rigorous work ethic.
