A multi-client study is a comprehensive research project conducted by a third-party organization that gathers and analyzes data from multiple clients in a specific industry or market. This type of study allows for a broader and more diverse perspective, as it combines the insights and expertise of various companies to provide a comprehensive understanding of a particular topic. Multi-client studies are often used to identify trends, opportunities, and challenges within an industry, and can provide valuable insights for businesses looking to make informed decisions and stay ahead of the competition.
