I pulled the spring pre-build against the last three seasons and the weather signal for the 22 Southeast stores.
| Signal | Finding |
|---|---|
seasonal_prebuild | Mulch on-hand hit 61% of plan the week temps broke 70°F |
dc_push | DC push started 9 days after the first-warm-week trigger, LY it was 2 |
attach.project | Soil and edging attach fell 18% at stores that gapped on mulch |
Recommend: tie the push trigger to the 10-day forecast instead of the calendar week, pre-position two truckloads at the 8 stores that gapped, and re-set the attach endcap.

Why Promos matters for Home retail
Home improvement promos drive traffic spikes, but most promotional purchases would have happened at full price within 30 days, the customer was already planning the project. True incrementality comes from triggering project starts, not discounting items already in someone's plan.
What Ward has eyes on.
The promos model runs each day, not on a reporting calendar. It catches the pattern, traces root cause, and attaches the next step before the number reaches a review deck.
Every one of your stores gets its own baseline. Ward tracks project basket value, seasonal accuracy, long-tail turn against it and surfaces only the deviations that hold up. The two that show up most in home retail are project basket identification and seasonal pre-positioning, and both are baseline problems before they are P&L problems.
Ward reads Snowflake rather than replacing it. Any table or view in your Snowflake account, cross-database joins, historical data at any depth come across on a read-only connection, get enriched with contextual data, and come back as findings. Your Data Platform is untouched.
At the metric level. Ward measures project-start incrementality, pull-forward rates by category, Pro vs DIY promotional response differences, and project basket value vs single-item sales. A 30-day pre/post window captures the full demand-shifting effect.
Why this combination
is its own problem.
Most promos projects stall at data access. This one does not, because Snowflake already exposes any table or view in your Snowflake account, cross-database joins, historical data at any depth through an API Ward reads directly.
- 01 Project-starter bundles typically generate 2-4x the basket size of equivalent single-item discounts but get treated equivalently in promo planning.
- 02 Pro customers and DIY customers respond to promos completely differently; chain-wide ROI averages obscure that Pro promos often have lower incrementality than DIY events.
Benchmarks. Home improvement holiday promo events show 40-90% gross weekend lift but typically 5-25% net incrementality after pull-forward and post-event drag. Project-starter bundles usually deliver 2-4x the incremental basket value of single-item percentage-off promos.
What the first 90 days
actually look like.
-
01
Week 1: connect
Read-only credentials to Snowflake. Ward reads any table or view in your Snowflake account, cross-database joins, historical data at any depth and starts building baselines. First daily cards land inside 48 hours, before baselines are stable, so you can see the shape of the output early.
-
02
Weeks 2 to 3: baselines
Ward needs roughly two weeks of history per store to separate a real deviation from normal variance. During this window the insight cards are directionally right and the thresholds are still moving.
-
03
Weeks 4 to 12: steady state
Ward returns findings on a daily cycle, each with the cause and the next step. Volume settles at a level a single person can read over coffee. The measure of success is not how many findings arrive, it is how many get acted on.

Your P&L surprises are born on the store floor. Ward solves this with automated insight cards: GMROI tracking by category with weekly insight cards. Inventory carrying cost alerts when capital efficiency drops. Working capital optimization recommendations based on turnover trends.
Ward delivers daily insight cards covering Project basket value, Seasonal accuracy, Long-tail turn, tailored for Finance decision-making. Each card includes what changed, why it matters, and what to do next.
Ward measures project-start incrementality, pull-forward rates by category, Pro vs DIY promotional response differences, and project basket value vs single-item sales. A 30-day pre/post window captures the full demand-shifting effect.
The Memorial Day event shows strong weekend revenue lift, but Ward's analysis reveals most of it was pull-forward from purchases that would have happened within 30 days, plus deal-seekers with below-average basket sizes. The highest-incrementality performers were project-starter bundles that triggered new project purchases. Ward recommends shifting future event strategy from broad discounts to project-starter bundles.
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.
