B2B data marketplaces are platforms that allow businesses to buy and sell data about other businesses, such as company information, financial data, and industry insights. These marketplaces are typically used by companies to gain a better understanding of their target market, identify new business opportunities and improve their sales and marketing efforts. B2B data marketplaces can be operated by data providers, independent third-party providers or a combination of both. Examples of B2B data marketplaces include ZoomInfo, Data.com, and Owler.
