An AI agent follows up on lost deals, 90 days later.

A consulting agency handed an AI agent the follow-up of its lost deals and former clients. Every morning, the agent proposes a follow-up in Slack; the salesperson reviews it and sends it from their own mailbox.

Results

  • Day 90

    Every lost deal gets one follow-up, 90 days after it was lost.

    By design

  • 0

    Emails sent without approval: each one leaves from the salesperson's own mailbox.

    By design

  • < 2 min

    To review and approve a proposal.

    Target

Commercial results (reply rate, reopened deals) will be published once the client has measured them.

01

The problem

Once a deal is marked "Lost" in the CRM, nobody follows up on it again.

  • Follow-ups depend on each salesperson's memory.
  • Former clients are on no follow-up list.
  • A good follow-up means rereading the whole record, and nobody has the time.

02

What we built

An agent that prepares each follow-up for the salesperson, without ever sending it on its own. The salesperson stays in control of every email.

Why this follow-up

Angle chosen: revive the project postponed for budget reasons, without talking price.

• Lost 3 months ago for "budget": the client postponed and never negotiated the price.

• New annual budget in January (call note from September 12).

Ruled out: offering a discount. The blocker was timing, not price.

  3. Three buttons

    Review, regenerate or ignore. The draft lands in Gmail, and the salesperson sends it when they want.

How it works

  1. 01

    Selection

    Every morning, the agent finds the deals lost 90 days ago in HubSpot. On Mondays, it adds former clients.

  2. 02

    Reading the record

    It rereads the loss reason, the last exchanges and what has changed at the client.

  3. 03

    Proposal in Slack

    It posts an angle, an email and its sources, tagging the salesperson in charge.

  4. 04

    Approval

    The salesperson reviews, edits if needed and saves the draft to their Gmail.

Next step. Sending straight from Slack, and a second follow-up when an email stays unanswered for two weeks.
