What is agent memory?
Agent memory is what an AI agent keeps from earlier work, such as past conversations, preferences and decisions, so it does not start from zero each time. A model's context window holds only the current session. Memory stores selected facts outside that window, often as files or database records, and brings them back when they are relevant. Well-designed memory lets users see, edit and delete what is stored.
Why it matters to a revenue leader
An agent without memory is a new hire every morning: capable, polite and unaware of what the customer said last month. Memory is what lets an agent recall that a facility manager prefers quarterly invoicing or that a renewal stalled over a price increase. It also creates a record of what the agent believes about your customers and sellers. That record needs the same care as CRM data: accuracy, access rules and a way to correct it.
Example
Fictitious numbersA sales manager at an environmental services company with 14 sellers uses an AI agent to prepare for one-on-ones. Because the agent remembers earlier sessions, it notes that a seller committed to re-engaging two lapsed agreements and asks what happened. When the manager spots an outdated note about a customer's budget, she deletes it so the agent stops repeating it.
"What do our AI agents remember about our customers and sellers, and who can see and correct it?"
