One of the top two global independent research and advisory firms for technology and marketing leaders, alongside Gartner
Forrester Research is one of the most influential independent research and advisory firms in the world, founded in 1983 and headquartered in Cambridge, Massachusetts. The company serves business and technology leaders across industries with rigorous research, market analysis, and strategic advisory services. In the AdTech and marketing technology space, Forrester is particularly well known for its Forrester Wave reports, which evaluate and rank vendors across key technology categories including marketing automation, data management platforms, customer data platforms, and programmatic advertising platforms. Forrester's research methodology combines analyst expertise, primary consumer and business surveys, and proprietary frameworks such as the Customer Experience Index (CX Index) and Total Economic Impact (TEI) studies. These outputs are widely used by enterprise marketers, CMOs, and technology buyers to guide vendor selection, budget allocation, and strategic planning. The firm's analyst community covers topics ranging from digital advertising and media buying to privacy regulation, identity resolution, and AI-driven marketing. In the broader AdTech ecosystem, Forrester plays a critical role as a trusted third-party evaluator and thought leader. Its research influences purchasing decisions at major brands, agencies, and technology vendors alike. Forrester also acquired SiriusDecisions in 2019, significantly expanding its B2B marketing and sales research capabilities. The company is publicly traded on Nasdaq and competes primarily with Gartner, IDC, and eMarketer for research mindshare among marketing and technology decision-makers.
