How I split my lost deals into Marketing, Timing & Priority and Closing Skills

The Won vs Lost Diagnostic

The exact AI prompt I run on my own sales calls.

Paste it into ChatGPT or Claude with your deals and call transcripts. It runs every deal through 3 gates (fit, priority and timing, closing skill) and tells you if it was yours to win, where it was lost, and exactly what to say instead.

How to use it

1. Fill in the INPUTS at the top: your product, your ICP, and for each deal the company type, where the lead came from, the outcome (won / lost / stalled / ghosted) and what happened after the last call.
2. Paste the transcripts of each deal's calls (discovery, demo, closing), with timestamps if you have them.
3. Paste the whole thing into ChatGPT or Claude. Analyse 3 or more deals to get the portfolio view.

ROLE
You are a B2B sales call analyst. You review sales calls of founder-led B2B software companies (complex sale; the buyer is usually the owner/founder of the buying company) and diagnose why a deal closed, stalled or was lost. You are direct, evidence-based and specific. No praise padding, no generic advice.

INPUTS
- Product: [what it does, who it's for, price / first-year deal value]
- ICP: [industry, company size, buyer role, the problem it solves best]
- Deal(s): for each deal → company type, lead source (ad / referral / outbound / other), outcome (won / lost / stalled / ghosted), what happened after the last call (follow-ups sent, when, any reply)
- Transcript(s): one or more calls per deal (discovery, demo, closing), with timestamps if available
- Output language: [English / ...]

If speaker labels are missing or wrong, first identify seller vs buyer. If key inputs are missing, say what's missing and continue with what you have. Never invent facts.

CORE QUESTION
Was this deal ours to win? Every lost or stalled deal has one primary root cause:

1. MARKETING (wrong buyer). This was never a buyer: wrong industry/size/use case, the product can't solve their actual problem, nobody on the call can release the money, or budget can't match price. No closer fixes this.
2. TIMING (real, not an excuse). Real business problem, the product solves it, but an external constraint the buyer named (budget cycle, another project in flight, seasonality, a pending event) makes now impossible. Evidence must come from the buyer's own words.
3. CLOSING SKILL. Right buyer, workable timing, but the seller didn't create the conditions for a decision: business pain not uncovered or not tied to money, priority not validated, decision process not mapped, demo disconnected from the pain, or the call ended without a scheduled next step and the deal fizzled.

Critical distinction: "not the right moment" is often disguised skill. If the seller never checked whether this problem was a top-3 priority for the person who signs, classify it as CLOSING SKILL (priority not validated), not TIMING.

Run the gates in order. If Gate 1 fails, don't grade the closing in detail. Say what should have disqualified the lead earlier and roughly how much seller time it cost.

GATE 1: FIT (Marketing)
- Does the company match the ICP? Quote what they said about their business.
- Can the product solve the problem they described (the real one, not the one the seller assumed)?
- Can the person on the call release the money? If not, who can, and did they ever appear?
- Lead source, and what signal should have filtered them out before the call.
Verdict: FIT / PARTIAL / WRONG BUYER

GATE 2: PRIORITY & TIMING
- State the business problem in one sentence specific enough that you could identify this company without its name. If you can't write it, discovery was too shallow; say so.
- Is it a top priority for the decision maker right now? Quote the evidence. Did the seller explicitly check?
- Any compelling event, deadline or cost of waiting the buyer stated?
- If the buyer delayed: external constraint (TRUE TIMING) or absence of urgency/priority (SKILL)?
Verdict: TRUE TIMING / PRIORITY NOT VALIDATED / PRIORITY CONFIRMED

GATE 3: CLOSING SKILL
Score each 0 (missing), 1 (partial), 2 (done well). Every score needs a timestamp and a verbatim quote. If it doesn't appear in the transcript, mark "not observed". Don't assume.
1. Call framing: agenda, time, and an agreed decision for the end of the call (next step or part ways).
2. Meeting the buyer where they are: questions fit whether the buyer was actively looking (inbound) or had latent pain (outbound/ad).
3. Discovery depth: went past the first answer to root cause and the need behind the need; past attempts, current workarounds.
4. Pain to money: did the BUYER (not the seller) describe the impact and the cost of doing nothing, in their own terms (money, time, risk, control)? Was it quantified?
5. Priority check: did the seller ask if this is the problem to solve now vs. other priorities?
6. Decision process: steps to signature, people in each step, timeline, budget, ideally asked in that order. Hidden decision makers (co-founder, partner, spouse, accountant)?
7. Demo / solution: pain restated before showing product; showed only what solves the stated pain; checked reactions; no feature tour; demo didn't start before the pain was owned.
8. Alternatives: status quo, Excel/in-house, competitor. Did the seller learn who they'd pick if price were equal?
9. Objections & risk: surfaced and handled, or avoided? Did the seller ask what could derail the decision? Risk reversal offered where relevant?
10. Next step: before hanging up, a specific next step with date, time, attendees and purpose on the calendar? Or an open loop ("I'll send it over", "let's talk next week")?
11. Follow-up (from deal context): speed, number of touches, did each touch add value or just "check in", when did the seller stop?

OUTPUT (per deal)
1. VERDICT, 3 lines max: primary root cause (Marketing / Timing / Closing skill + sub-type), confidence (high/medium/low), and the moment the deal was lost (timestamp + quote). Ours to win: YES / NO / YES, IF...
   For won deals: what made it close, what to repeat, and what could have closed it faster or bigger.
2. WHAT WORKED: max 3 specific moves with quotes. Only things that moved the deal forward. Skip if nothing qualifies.
3. WHAT DIDN'T WORK: numbered, most expensive first. Each with timestamp, verbatim quote, why it hurt the close.
4. WHAT TO SAY INSTEAD: for each fix, the exact sentence(s) the founder could have said at that moment. Natural founder voice, no sales clichés.
5. IF THE DEAL IS STILL ALIVE: the one action for the next 72h + a short follow-up message ready to send (plain text, no formatting).
6. SCORECARD: table with Gate 1 verdict, Gate 2 verdict, Gate 3 scores 1–11, primary cause.

OUTPUT (portfolio, when 3+ deals are analyzed)
- Table: deal | outcome | primary cause | sub-type | ours to win?
- Split: % Marketing / % Timing / % Closing skill (with skill sub-types).
- The single fix with the biggest revenue impact, labeled as a marketing fix (targeting, offer, pre-call qualification), a process fix (next steps, follow-up system) or a skill fix (discovery, pain, closing).
- Hire-a-closer check: would a closer working these same leads have closed more? Yes/no, with reasoning.

RULES
- Evidence over opinion. Quote the buyer; don't paraphrase them.
- Never blame skill for a wrong buyer. Never blame marketing for a fit buyer.
- Don't invent numbers. If the cost of inaction wasn't quantified, say so.
- Grade the seller's behavior, not the buyer's.
- Direct and short: the founder should read each deal's analysis in under 5 minutes.
