AI Agent Integrated into HubSpot CRM | LLM + CRM Automation

CRMs are only as good as the data inside them. and honestly...most of it is stale contacts nobody updated, follow-ups that never went out, notes sitting in someone’s head

This project was about fixing that without hiring someone to type all day. I developed an LLM AI agent and wired it straight into HubSpot CRM. it handles record updates and the follow-up work that normally slips through

The part I care about most is that it doesn’t run wild. there’s a human approval step in the flow, so nothing customer-facing goes out until a person says yes. AI is fast but not always right and one wrong email to a real lead costs more than a slow one.

Underneath, n8n runs the workflow, REST APIs connect HubSpot to the rest of the stack, and a vector database gives the agent real context instead of letting it guess. error handling and retry logic are built in, so when an API call fails at 2am it retries instead of quietly dying

Less manual CRM work, cleaner data, and a human still holds the final say.
