Test it before you build it
$2,150 · 5 weeks · 30 prospects
For $2,150 and 5 weeks, prove that independent retailers will actually keep tagging inventory after week one and that local brands will prepay $500 for the sell-through data - using off-the-shelf readers, before any software is built.
Riskiest assumption · Staff at independent specialty stores will keep tagging every incoming item as a daily receiving habit after the novelty fades, because the reorder and shrink alerts matter enough to the owner to enforce it - and local brands will pay real money for the sell-through data that habit produces.
1Focus group: who and where
Two people in the Denver-Boulder metro: the owner-operator of a specialty food or beverage store (1-3 locations, no IT staff) who eats shrink and stockouts personally, and the founder or head of sales of a local brand doing $500k-5M through 20-200 independent stores who learns about a sell-out only when the reorder fails to arrive.
where to find 30 · The Naturally Boulder member community for local brand founders, the Specialty Food Association member directory filtered to Colorado as a brand and retailer list, the published vendor lists of the Boulder County Farmers Markets, and a Google Maps sweep of independent bottle shops, co-ops and specialty grocers in Denver-Boulder as the retailer walk-in channel.
2Sell first, build later
For brands: live sell-through, stock and shelf-age data for your SKUs across up to 10 named Denver-Boulder stores, tags supplied and applied, dashboard live within 30 days of payment, 90-day pilot. For retailers: a $399 founding-price reader kit with 6 months of tags free, delivered in October 2026, with automatic reorder and shrink alerts.
the ask · Brands: $500 prepaid for the 90-day, 10-store pilot, then $75 per store per month. Retailers: $399 one-time kit at the founding price, reserved with $100 down.
a real yes · A real yes is a brand's $500 prepayment landing in the account or a retailer's $100 deposit at checkout; a store letting us install a free loaner, 'we'd definitely look at this', and unpaid dashboard access do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Two-week tagging habit trial
$1,800 · 21 days
Buy three off-the-shelf UHF handheld readers and 5,000 preprinted tags, recruit 5 stores in person with the offer of a free kit loan plus a weekly shrink-and-slow-mover report, and have staff tag incoming items as part of receiving. The founder visits twice a week, counts tagged versus received units from invoices, and watches whether week-2 behavior holds without prompting.
keep going if · 4 of 5 stores tag at least 80% of incoming units in week 2 with no reminder from us
2. Brand prepaid data pilots
$150 · 14 days
Pitch 15 local brand founders from Naturally Boulder and the SFA directory a live dashboard of sell-through, stock position and shelf age for their SKUs across the trial stores. The ask on every call is a $500 prepaid 90-day pilot covering up to 10 stores, tags included; a mockup dashboard with real trial-store data is the demo.
keep going if · 5 of 15 brand founders prepay $500; fewer than 2 means the brand subsidy engine does not exist
3. Retailer founding kit pre-orders
$200 · 10 days
Offer the 5 trial stores plus 10 more walk-ins a founding deal: $399 kit (below the $500 list) with 6 months of free tags, reserved with a $100 deposit at a simple checkout page, October delivery. Present it in person at the end of the trial with each store's own shrink numbers on one page.
keep going if · 6 of 15 retailers put down the $100 deposit
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$500
per prospect, refundable
how · For the brand, the primary payer: a $500 pilot order prepaid by card or ACH at a checkout page after the call, which is the small-business-appropriate instrument of a prepaid first period rather than a contract; the founder signs a one-page pilot order naming the stores. Retailers separately reserve kits with a $100 checkout deposit. set up: Stripe Checkout ↗
what it reserves · One of 10 brand slots in the first Denver-Boulder cohort, tags for up to 10 stores included, and the $75 per store per month price locked for a year.
refund · Refunded in full if the brand's live dashboard is not showing real store data within 30 days of payment, or on request any time before tagging starts.
target · 5 brand prepayments of $500 from 15 pitches, and 6 retailer deposits of $100 from 15 offers, within 35 days
Go: build it if
4 of 5 trial stores still tagging 80%+ of incoming units in week 2, plus 5 of 15 brands prepaying $500 and 6 of 15 retailers down $100 - habit and money on both sides.
Kill: stop if
Week-2 tagging falls below 50% of incoming units in 3 or more of the 5 trial stores, or 1 or fewer brands prepay after 15 pitches - either one means the network never forms.

outreach message
You find out a store sold out of your product when the reorder finally shows up - or never does. We are wiring specialty retailers across Denver-Boulder with RFID shelf kits: every tagged unit of yours reports sell-through, stock position and shelf age daily, all your stores in one dashboard. The 90-day pilot is $500 prepaid for up to 10 stores, tags included and applied for you. Do you have 20 minutes this week to see the dashboard with real store data in it?
landing page
See your sell-through in every store, live, every day. $500 prepaid 90-day pilot: up to 10 Denver-Boulder stores, tags included, then $75 per store per month locked for a year. Claim one of 10 brand slots in the October cohort.
deposit terms
Your $500 prepayment reserves one of 10 brand slots in the October Denver-Boulder cohort and covers your full 90-day pilot across up to 10 stores, tags included.

The idea in full
- What
- Shelfgrid sells a sub-$500 RFID reader kit plus cheap tags to independent retailers and the small consumer brands that stock them. Every tagged item reports sell-through, stock position and shelf age in real time; brands see live data across every store that carries them, and retailers get automatic reordering and shrink alerts without a POS migration. Revenue starts in year one from kit sales and per-store brand subscriptions.
- Why now
- Tag and reader costs have fallen far enough that an NSF I-Corps award (~$50k) is funding RFID digital inventory even in shellfish aquaculture, and Adrich (Alchemist Class 41) is putting usage sensors into consumer packaging - item-level tracking is finally cheap enough for stores with no IT staff.
- Wedge: first customer and entry point
- Fifty specialty food and beverage retailers in one metro plus the ten local brands they all stock; the brands subsidize the tags to get sell-through data they have never had, which recruits the retailers for free.
- Path to 100x
- Retail inventory and shelf analytics for the long tail of stores is a $10-100B market with no incumbent, because every existing system assumes chain-scale IT. The mechanism is a two-sided network: each new store makes the dataset more valuable to every brand, each brand subsidy recruits more stores, and the winner becomes the default demand signal for independent retail - a category that does not exist today.
- Ceiling
- If the network stalls at a few thousand stores, this is a niche hardware vendor with reseller economics, not a data network, and tops out well under $1B.
- Closest real companies, as the generator saw them
- WVN sells in-store analytics to large retailers from camera and sensor data; Adrich instruments individual packages for brands. Shelfgrid instead makes the retailer-brand pair the unit, so the same tag serves both sides and the value grows with each store added.
- Main risk
- Independent retailers abandon the tagging habit after the novelty fades, and without dense retailer coverage the brand-side data product never becomes worth paying for.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
3/5
Brand-subsidized tags recruiting retailers is a genuine two-sided flywheel, but reader kits placed store-by-store by field teams make density expensive.
Bootstrapper
3/5
Sub-$500 kits and year-one revenue are affordable, but brands subsidizing tags and retailers abandoning the scanning habit make retention the weak point.
Operator
2/5
Every item must get tagged by staff at fifty independent stores - the model dies on a daily workflow change the retailer gains least from.
Technologist
2/5
Sub-$500 readers and cheap tags are commodity RFID; the defense is retailer density and habit, not anything hard to build.
Risk
3/5
Ten local brands subsidizing tags is the recruiting mechanism, so brand-side budget cuts stall retailer acquisition before density arrives.
trends
2/5
Falling RFID tag costs are a decade-long curve, not a 2025-2026 shift; an NSF I-Corps award is not a timing signal.
