Consultants and Agencies to Support B2B Post-Sales Customer Lifecycle Strategy and Execution

For the B2B CLM 300+ Newsletter, I’m putting together a list of consultants/agencies that can help B2B companies with both the strategy and execution of the post-sales customer lifecycle. Typical tasks: data cleanup, segmentation, omni-channel, behavior-based nurture campaigns, cross-sell, repeat buyers, etc. What I'm seeing is openings not getting filled. As a stop-gap, consultants may be able to get the engine started.
