Lithium is an enterprise-grade social community platform, which is most commonly used to allow for interactions between B2B and B2C customer, prospects and partnering in either a Support (call deflection), Marketing or Collaboration environment or context. Communities deployed by its customers are predominantly external-facing. The product is modular, so it can be expanded with additional functionality over time. Lithium offers connectors to popular enterprise backend systems, such as Salesforce. Additional connections or functionality can be programmed via APIs. Most customers use professional service organizations to launch Lithium for them.
