How it runs. Ward isolates incremental volume from baseline, measures cross-SKU cannibalization, estimates pull-forward effects, and calculates true ROI.
How the connection works. Ward connects via Snowflake SQL API with key-pair authentication. Read-only warehouse. Your data never leaves Snowflake.
The short list
- Net lift measurement (not gross)
- Cannibalization quantification
- Pull-forward detection
- Promo ROI scorecards

I pulled Store 37’s last 28 days against the chain baseline. Two root causes, both compounding.
| Signal | Finding |
|---|---|
labor_efficiency | Rev/labor-hour −22% vs. cluster, staffing mismatch at 11a–1p peak |
inventory.fresh | Fresh fill 83%, backroom replenishment lag at 2–4p |
promo.lift | BOGO crackers cannibalized Brand Y by 28%, net category +6% |
Recommend: re-baseline Store 37 schedule against true peak, raise replen window to 1p, and review the BOGO before next cycle.

Why Promos matters for Grocery retail
Most grocery chains measure promotions by gross lift, ignoring cannibalization, pantry loading, and margin erosion that destroy actual ROI. Ward isolates each effect to calculate true net promotional lift, giving category managers evidence to kill underperformers and concentrate spend where it generates real incrementality.
What Ward has eyes on.
The connection to Snowflake is read-only and runs on your schedule. Ward ingests any table or view in your Snowflake account, cross-database joins, and the rest of the feed, then combines it with external context your Data Platform does not carry: weather, local events, competitor pricing.
The promos model runs on a daily cycle, not on a reporting calendar. It spots the pattern, explains root cause, and attaches a recommended action before the number reaches a review deck.
Ward keeps a running read on 30,000+ SKUs over your stores, at the store-category level rather than the chain roll-up. The metrics under watch include fill rate, shrinkage %, fresh waste %. A roll-up hides a single-store problem inside a healthy average, which is how fresh waste & spoilage stays invisible for a quarter.
At the metric level. Ward decomposes promo results into gross lift, cannibalization rate, pantry loading, halo effects, and true incremental margin contribution. It also tracks promo fatigue, when repeated discounts permanently shift baseline demand downward.
Why this combination
is its own problem.
Promo Effectiveness produces a lot of output that is technically correct and operationally useless to procurement. Ward filters on whether the finding changes a decision a Head of Procurement can actually make.
- 01 Halo effects are credited to the wrong promo because chains run 3-5 overlapping events at any time and don't isolate which one drove what.
- 02 Vendor-funded promos look ROI-positive on margin reports because the funding offsets the visible discount, while cannibalization erodes the rest of the category.
Benchmarks. Grocery promos typically show 30-80% gross lift but only 10-25% net incremental lift after cannibalization and pull-forward. The vast majority of promos are net-margin-positive only after vendor funding; remove the funding and roughly half lose money.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Snowflake. Ward pulls from any table or view in your Snowflake account, cross-database joins, historical data at any depth and starts building baselines. First findings land inside 48 hours, before baselines are stable, so you can see the shape of the output early.
-
02
Weeks 2 to 3: calibration
Baselines stabilize per store and per category. Ward stops flagging normal variance and starts flagging exceptions. This is the window where the false positive rate drops sharply.
-
03
Weeks 4 to 12: operating rhythm
Cards arrive daily and get triaged like any other queue. Most teams find the volume settles into something one person clears in ten minutes. What matters is the action rate, not the alert count.

Ward delivers daily insight cards covering Fill rate, Shrinkage %, Fresh waste %, tailored for Procurement decision-making. Each card includes what changed, why it matters, and what to do next.
Ward decomposes promo results into gross lift, cannibalization rate, pantry loading, halo effects, and true incremental margin contribution. It also tracks promo fatigue, when repeated discounts permanently shift baseline demand downward.
A major snack vendor proposes a co-op BOGO program across 12 SKUs. Gross lift looks strong, but Ward shows net category lift is minimal after accounting for cannibalization and pantry-loading pull-forward. Several SKUs generate negative net category contribution. Ward provides SKU-level promo scorecards the category manager uses to restructure the deal around the SKUs with genuine incremental lift.
First insight cards arrive within 48 hours of data connection. Ward needs approximately 2 weeks to establish stable baselines for your specific operation.
No. Ward sits on top of your existing stack. It is the proactive intelligence layer that watches your data continuously and delivers insight cards, so your team acts on findings instead of hunting for them.
