- Equipping Sales and Customer Success with customer-centric messaging, adoption toolkits, executive business review materials, ROI content, playbooks, and trigger definitions

- Working with Marketing Operations, Revenue Operations, and Customer Success Operations to improve segmentation, data quality, trigger detection, automation, attribution, and reporting
