What it does

  • Pulls the last year of closed lost deals and their call transcripts
  • Puts the buyer's exact objection next to each account
  • Checks if the objection still holds or the blocker has left
  • Finds the new company of past champions
  • Drafts a follow up only when it can say what changed

Your approval boundaries

Approval required

These actions always wait for your yes:

  • Sending any follow up
  • Opening new deals in the CRM

You decide what happens next.

More about this workflow

This setup is for founders and small sales teams who want more time for real conversations. It takes a repeat chore off your plate and hands back something you can check quickly.

First, it pulls the last year of closed lost deals and their call transcripts. Next, it puts the buyer's exact objection next to each account. Then it checks if the objection still holds or the blocker has left. After that, it finds the new company of past champions. Finally, it drafts a follow up only when it can say what changed. It works with your CRM, call recorder and web search, each on its own login with limited access.

You get the prep work done and waiting for you. The agent stops and asks for your yes before sending any follow up and opening new deals in the CRM, and says plainly if a step cannot be undone.

“The person who killed your deal might have just left the company.”

A person sends, pays, posts, or deletes. - Keep a short log of every action you took and every source you read. - If you are unsure, ask instead of guessing.

Run your workflow

Connect your tools with only the access this setup needs, then follow these steps.

Steps

Do these in order. Test on old data before it touches live work.

  1. 1Connect HubSpot CRM with its own login, not yours. Grant read scopes, plus notes write.
  2. 2Set up Call recorder. Keep it to read access to transcripts you choose.
  3. 3Set up Web search. Keep it to public search results only.
  4. 4Paste the prompt where your harness takes instructions. See the note under the Copy button.
  5. 5Do a dry run on old or test data first. Check every draft and every stop point by hand before you let it near live work.
  6. 6Read its log after the first real run. Only widen access once a week of runs looks clean.

Safeguards and trust score

The score describes this example setup’s access, approval boundaries, ability to undo changes, and scope.

Access18 / 30

Can draft things that send or spend, so it sits close to risky actions.

Human approval30 / 30

Waits for a yes on: sending any follow up, opening new deals in the crm.

Undo and logs14 / 20

Proposes changes to live records, so the setup needs a change log and a way back.

Scope16 / 20

Runs on its own login across 3 tools. Fewer connections means a smaller blast radius.

How to raise it

  • Access: Take away its ability to send, post or spend. Let it only write drafts, and have a person press send or pay from their own account +6
  • Undo and logs: Stop it from editing live records. Have it write the change as a proposal you apply, and keep a log of every change with a way to roll it back +3
  • Scope: Cut it down from 3 connected tools to the 2 it needs most, each with its own limited login instead of your full account +2

Do all of these to reach 89, up from 78.
