LinkedIn launched Sales Navigator as a standalone product in July 2014 to help sales professionals manage relationships. Over the following years, LinkedIn made frequent enhancements to Sales Navigator, adding new features, expanding language support, and integrating with additional CRM systems. Examples include the launch of mobile apps in 2014, new lead recommendation capabilities through integrations with Salesforce in 2014, and the introduction of Sales Navigator Lite for Gmail in 2017. The timeline shows LinkedIn's continued efforts to improve Sales Navigator and make it a key resource for sales teams.
