# Closed-Won Handoffs: From 20% to 100% with an AI Summary

Client: a K-12 education company. What I did: designed and built it end to end. Tools: HubSpot workflows, HubSpot AI data agent.

## The Problem

Across 17 sales reps and 14 customer success reps, only 20% of closed deals came with a handoff. Reps were inconsistent, and many left no summary at all. Customer success had to dig through CRM records by hand, which took 30 to 60 minutes per deal. At 5 to 6 deals a day, that was a lot of lost time.

## What I Changed

I built a workflow that triggers the moment a deal moves to Closed Won. It runs a HubSpot AI data agent over all of the deal's activity: call transcripts, emails, calls, and notes. The agent writes a handoff summary and pins it as a note on the deal. The summary covers who the buyer is, their pain points, what they want to accomplish in the first 30 days, what success looks like to them, and more.

## Keeping the AI Honest

Because the summary is AI-written, I wrote a detailed prompt that tells the agent to use only the data on the deal. If a question has no answer in the data, the summary says 'no data found' instead of guessing.

## Results

- Handoff coverage went from 20% of closed deals to 100%, because the trigger is the Closed Won stage itself.
- Customer success gets up to speed in minutes, down from 30 to 60 minutes of CRM digging per deal.
- Handoff quality no longer depends on which rep closed the deal.
- Customer success saves 12+ hours a week that used to go to digging through deal records.
