# A marketing agency wakes up 1,000+ old leads and closes a $200K deal with an AI prospecting agent

Major Tom, a digital marketing agency, pointed HubSpot's Prospecting Agent at its old, dormant leads. It re-engaged 1,000+ of them, booked 24 meetings in 3 weeks, led to more than $750,000 in proposals, and one deal of about $200,000 closed as a direct result.

## Problem

Major Tom had about 7,000 dormant contacts going back to 2020 and no reliable way to re-engage them at the quality they deserved.

## How to do this

1. HubSpot Prospecting Agent
2. Old leads that once showed interest
3. A person to book the meeting when someone replies

## Verdict

Old leads get a new note in your voice, and a person books the meeting when someone replies.

## Tools

- [HubSpot Prospecting Agent](https://www.hubspot.com/products/artificial-intelligence): Writes to old leads and hands replies to a person


## Result

Re-engaged 1,000+ dormant leads, 24 meetings in 3 weeks, $750K+ in proposals, and one deal of about $200,000 closed as a direct result; active pipeline grew about 30%
