Pitching
Verify a Market Statistic Before It Goes in Your Deck
Make your pitch statistics defensible. Use a claim-to-source ledger to check the population, period, denominator and conclusion behind a number.
What you will learn
- Trace a market claim to its original evidence.
- Check population, denominator and observation date.
- Rewrite a claim so the source actually supports it.
Before adding a market statistic to your deck, open the original source and check what it actually measures. Match the population, period, geography, unit and wording to your claim. A relevant-looking number is not enough if it answers a different question.
Trace the number past the summary
A search snippet, AI answer or blog may point toward a useful source, but it is not a substitute for reading that source. Follow the citation to the original report, dataset or survey methodology. If the primary evidence is unavailable, label the claim unverified or leave it out. Do not cite the latest article in a chain of articles that cite each other.
For survey-based claims, AAPOR’s disclosure checklist helps identify the population, sample, questions, dates and methods you need to inspect. Use the original provider’s own definitions for other datasets.
Use a claim-to-source ledger
Original source-check worksheet
| Field | What to record |
|---|---|
| Proposed claim | Exact sentence that will appear in the deck |
| Original source | Publisher, report, table or page, stable link |
| Measured unit | People, firms, transactions, dollars, seats or accounts |
| Population | Inclusion rules, geography, stage and sector |
| Period | When the underlying events occurred, not just publication date |
| Denominator | All eligible units or only disclosed/responding units |
| Coverage limit | Missing values, selection effects and revisions |
| Verdict | Supported as written, rewrite, hold or remove |
Work a fictional mismatch
Imagine a source reporting that 60 of 100 responding enterprise teams use at least one automation tool. A draft deck says “60% of all small businesses want our workflow product.” That changes the audience, behavior and object of interest.
Repair the claim without borrowing its meaning
| Check | Source | Draft error |
|---|---|---|
| Population | Responding enterprise teams | All small businesses |
| Observation | Uses an automation tool | Wants this product |
| Denominator | 100 survey respondents | Entire market implied |
| Time | Specific survey period | Timeless demand implied |
A faithful sentence is: “60 of 100 responding enterprise teams reported using at least one automation tool during the survey period.” That may still be irrelevant to a small-business pitch. The right next move may be finding better evidence, not forcing this statistic into the deck. The example and number are fictional.
Separate arithmetic from research
If you multiply a sourced account count by an assumed annual price, the result is your market-sizing scenario. Label the price assumption and explain the reachable subset. The source did not independently verify your resulting revenue opportunity. Use the bottom-up TAM worksheet for that separate calculation.
Check percentage points versus percentage growth. A rate moving from 10% to 15% increases by five percentage points and by 50% relative to its starting value. Those are different descriptions of the same movement, not interchangeable units.
Keep uncertainty in the caption
A short, useful caption can state: source and table, observation period, geography, definition and one material limit. Put the source near the claim, not only in a final bibliography that a reader cannot map back to the chart. Keep a fuller internal evidence record for diligence.
If two credible sources disagree, compare definitions before choosing the larger number. A total addressing one geography or a forecast for a later year may not contradict a smaller current estimate. Avoid turning disagreement into false precision.
Practice with one sentence
Choose the most important outside statistic in your deck. Complete the ledger, then try to disprove your own wording. If it survives, keep it. If not, rewrite the sentence, change the source or remove the number. A clear qualitative explanation is better than a statistic you cannot defend.
In Finta, keep the reviewed evidence with the materials used in investor conversations. When a source changes, record which claims and follow-ups need attention. That keeps your fundraising story consistent without pretending the research is more complete than it is.
