• Contact discovery: Let the agent browse people, pull individual profiles and field data, and see each person's related lists and entries.
• Opportunity review: Direct your agent to list investment opportunities or retrieve the core details of a specific opportunity for deal research.
• List analysis: Instruct your agent to explore available lists, inspect their fields, and review company, person, or opportunity entries with relevant details.
• Saved view reporting: Have your agent discover saved views, inspect their setup, and retrieve the matching rows for focused portfolio or pipeline analysis.
