One question, of your own Illustrative
> Did the Q3 discount pay for itself - or just pull demand forward?

Of the measured lift, 61.4% came from buyers who had ordered in the prior 90 days - the demand was mostly already there.

THE Q3 REVIEW
Why it matters

Forecast. Then forget.

Every business forecasts - budgets, demand plans, pipelines. Almost none keeps a graded record of what was predicted, which assumptions drove it, and what actually happened. The same assumptions drive the next decision. Repeated error, no institutional learning.

The backlog

The questions you already have.

Queued behind the data team's backlog - or never asked, because asking used to mean a two-week analysis request.

CEO / CFOWhen we raised prices 8 percent, what really happened - to margin, churn, and repeat purchases?
COOWhich outlets are actually underperforming, once you account for location, footfall, and weather?
CMO / CRODid the discount campaign bring in new customers - or just give margin away to people who would have bought anyway?
DeltaBook Enterprise

Ask in plain English.

State the belief in ordinary language. DeltaBook turns it into an explicit test - the proposed assumptions and data shown before anything runs. You approve, the engine computes - and every figure carries its sample size.

How it works

Five steps. No code.

01
Connect
Your data, in a private, isolated environment.
02
Organize
Clean up and organize your data so it's easy to pull from.
03
Ask
Plain-English questions. The engine proposes; you approve; it computes.
04
Test
Reconstruct what would have happened - using only what was known at the time. Sample sizes shown. When there's no signal, we say so.
05
Track
Keep what holds. Every forecast grades against what actually happened.
Trust, by construction

Every conclusion has a receipt.

Every number is computed - never generated by AI. Inputs, sample, method, timestamp: click any figure and see exactly how it was built, as of what moment. When the evidence is mixed, the answer says so.

The record

Track the Difference.

Forecast vs actual, graded automatically - permanently attached to the exact strategy version that made the call. Find out whether your forecasting was ever right. And keep finding out.

The decision room

Call the meeting.

Most owners are the domain expert - what they lack is the bench. Ask one question and every lens answers: finance, revenue, operations, marketing, each reading the same computed evidence through its own metric library. A factual dispute becomes a test, not a longer meeting. You keep the chair; the decision and its forecast freeze, and reality grades them.

Roadmap - direction, not shipped product
What you bring

Your data, your questions.

Upload what the business already has - the AI cleans it into a structured bank. Then test the questions you argue about in meetings, and get a computed answer with a record. A few that owners bring:

Did the Q3 discount pay for itself, or just pull demand forward?
Orders . pricing . margins
Which channel's leads actually close - not just click?
Marketing spend . pipeline . wins
Does our fastest delivery lane actually keep customers?
Logistics . churn . lifetime value
Did the onboarding change move 90-day retention?
Product usage . cohorts
Is the new supplier cheaper once defects are counted?
Procurement . quality . returns
Does adding support headcount actually cut resolution time?
Staffing . tickets . SLAs

Whatever the question, the workflow is the same one you saw the instrument run: describe the belief, confirm the test, read the computed answer, keep the record.

A shared memory for the whole business.
