Here is a new CRM Lead Management Magic Quadrant from Gartner.
Lead management integrates business process and technology to close the loop between marketing and direct or indirect sales channels, and to drive higher-value opportunities through improved demand creation, execution and opportunity management.
The two leaders are Eloqua and Marketo, the leading “Marketing Automation” vendors. CRM systems like salesforce or Microsoft Dynamics have basic lead management.
Leaders in the CRM lead management market provide market-leading functionality that supports B2B, B2B2C and B2C lead management processes across multiple channels, and supports both outbound and inbound marketing processes
The summary is shown below but you can get the full report from Gartner or some of the vendors,
