The company operates from 500 E Pike Street, Suite 200A, Seattle, Washington 98122 and supports campaigns in the United States as well as EMEA, APAC and Latin American markets.

Add3 states that it manages more than $150 million in annual media spend. Its client model organizes specialists around individual channels while using shared reporting and strategy to coordinate acquisition across platforms. The company reports an average client engagement of more than five years, which is notable in performance marketing where agency relationships can be relatively short. Add3 emphasizes continuing optimization and direct platform expertise rather than one-time campaign setup.
