Swappable battery, spare parts and take-back: the device must not become trash.
Buy for the week you’ll actually have.
A clip-on cart device and app that stops food waste at the shelf, before checkout

Swappable battery, spare parts and take-back: the device must not become trash.
Audited factories; English and Spanish voice access.
Opt-in consumer data only; never sold to stores.
Once, in the app. Choose “Busy week,” “Cooking 2 nights” or “Eating out likely.”
One tap on the handle as each item enters the cart.
Reduce, smaller pack or skip. The shopper keeps control of the final decision.
Two short videos add context to the three-step concept: the first is the product video provided by our team; the second is a 30-second extract (1:42–2:12) from the final narrated presentation.
A closer look at the ShopperPal product concept.
Open video separately ↗A short explanation taken directly from the complete final presentation.
Open excerpt separately ↗These videos explain the proposed solution; they do not represent a commercially deployed product or validated waste savings.
One-tap fix before checkout: reduce, smaller pack or skip. 21 of 23 cut the salad kits after one warning in the simulation.
Builds itself from the cart. One question, once, no list.
Money spent, next to money not wasted. This would be an estimate, not a measured saving.
Pay from the app and skip the line. Needs a store partner, at the earliest Phase 2.
Buying right is the proposed saving
No list and no logging
Learns what the household finishes
Two questions sort every alternative: does it act at the shelf, before checkout; and does it work for the shopper or for the store?
Narrow claim: we found no smart-cart tool built to reduce household food waste. Competitors and substitutes do exist.

fine without the device: phone app or either
$150 price − $48 build and import − $10 shipping − $12 fees and warranty = $80 profit per device
Three free months, then $10/month. $8.68 after app store fees × 17 paid months on average = $148 profit per owner

Year 1: −$230k · Year 2: +$272k · Year 3: +$651k.
54% modeled ROE = 15% net margin × 3.6× asset turnover × 1.0× equity multiplier. No debt.

Less than ~$200k drawn before Kickstarter

Only after deliveries
If Kickstarter fails, the plan stops after approximately $200k of spending; the remaining angel commitment is not drawn.
Section owners, internal deadlines, whole-team coordination.
Drafts in Drive. Challenge ideas, not people.
Three-hour integration; quality gate before deadline.
Clear ownership and constructive challenge.
Conflict avoidance and late integration → every voice heard, early drafts, earlier quality gates.
| Our plan | What the tests say |
|---|---|
| $150 device | Only 2/10 would pay $100+ |
| $10 per month | 6/10 chose $5 per month |
| Dedicated clip-on | 8/10 fine without the device |
| Model assumes opt-ins | 0/4 left email after seeing the report |
The device beats the phone app.
People leave deposits at $150.
A store chain allows the clip.
Factory quotes keep landed cost near $50.
1 · Start from the problem: seeing food didn’t stop waste.
2 · Cheap tests beat polished plans.
1 · Clear ownership lets a remote team move fast.
2 · Ownership without an integration point creates gaps.
1 · Unit economics before volume.
2 · With no debt and nothing owned, asset turnover drives ROE.
