An information marketplace is provided in which information items are received from various sources. Each item and the item providers carry descriptors that identify various attributes of the information being provided and by whom it is being provided. Requests for information are received from information consumers that are also tagged with attributes describing the consumer and the information being requested. A subset of the information available in the marketplace is provided to the consumer based on a degree of match among the characteristics describing the information, the attributes associated with the provider of the information, and the attributes associated with the consumer without identifying the actionable investment opportunity to the information consumer or identifying the information consumer to the information provider.
