Turning a call transcript into a proposal in ten minutes

Why speed matters more than polish

The call ends. The prospect has six other things to do this afternoon. By Thursday, you're competing with the memory of your own call — blurrier each day.

A proposal that lands within two hours of the call doesn't have to be better than the one that lands Thursday. It just has to be there. Momentum is the point.

The loop

We run the call through Fathom. Fathom produces a transcript. We paste the transcript into Claude with this prompt:

Below is the transcript of a discovery call with [Company]. Write a 2-page proposal based only on what was said. Structure: (1) the problem, in their words, (2) what we propose, (3) scope — tasks and exclusions, (4) timeline in weeks, (5) price per month, (6) what's included. Do not invent services they didn't ask about. Do not pad.

Claude produces a draft. We edit for maybe 15 minutes. Branded PDF out the door.

What makes this better

The proposal quotes the prospect back to themselves. Their exact phrasing about the problem. Their specific numbers. Their vocabulary. That alone converts better than any amount of glossy design.

What to never do

Don't add services they didn't ask about. Every agency does this. "We noticed you could also benefit from..." The prospect rolls their eyes. Claude, if you let it, will also do this. The prompt above specifically forbids it.

Don't use a template. We have a layout, not a template. The words change for every proposal because every call is different. The moment your proposals all sound the same, you're losing deals to ones that don't.

The thing that actually closes

The last section — "What's included" — is where most proposals fail. People write fluff ("dedicated account manager," "weekly sync") and miss what the prospect actually said they wanted.

Good version:

What's included: - 250 researched LinkedIn messages per week, targeting the Heads of Data Engineering in APAC that you identified on our call - Weekly call review — we listen, you just run your calls - Proposal writing service for every closed meeting - A live client dashboard at report.prospectengine.com/decube

Specific. Scoped. Accountable.

The 2-hour turnaround

We aim to send every proposal within 2 hours of the call ending. This is non-negotiable for our team. It requires:

• Recording every call (Fathom, no exceptions)
• A standing proposal layout (Notion template, exports to PDF)
• Claude draft time: ~8 minutes
• Human edit time: ~15 minutes
• Export, brand, send: ~10 minutes

If we can't do it in 2 hours, it's because we're busy, not because the system doesn't work.

We do this for every proposal we write. It's part of Revenue. Or steal the prompt — it's the same one we use internally.
