A data broker in the tech industry functions as an intermediary that collects, analyzes, and sells consumer data. These companies aggregate vast amounts of information from various sources, including social media, public records, and online activities. Their analysis helps businesses target specific audiences and personalize marketing efforts more effectively. Additionally, data brokers can provide insights on consumer behaviors, preferences, and trends, which can be invaluable for companies looking to enhance their strategies and improve decision-making. However, this practice raises privacy concerns regarding the handling of personal information.
