Test it before you build it

$1,500 · 4 weeks · 25 prospects

For $1,500 and 4 weeks, prove that growers will put $100 down on a counting kit that does not exist yet and $1,000 into pilots that do.

Riskiest assumption · A shellfish or nursery grower will pay up front for item-level counting of their own stock alone, before any trading partner owns a reader and before the one-cent tag exists.

1Focus group: who and where

Owner or operations manager of a US shellfish farm or wholesale plant nursery with 5-50 staff, who counts cages, bags and pots by walking the rows and discovers the shrink months later at settlement or sale.

where to find 25 · East Coast Shellfish Growers Association member network and newsletter (community); state shellfish aquaculture lease registries such as the Virginia Marine Resources Commission's public lease list, plus the AmericanHort member directory for wholesale nurseries (lists); the Pacific Coast Shellfish Growers Association annual conference this fall (event).

2Sell first, build later

Two things sold before any custom silicon: a $499 starter kit (one handheld reader plus 500 rugged tags, Q2 2027 delivery) reservable today, and a 60-day paid pilot starting this October that counts one real product line with commodity tags.

the ask · $100 refundable reservation against the $499 kit; $1,000 per pilot, invoiced up front

a real yes · A card reservation or a paid pilot invoice with a calendar start date is a yes; 'this would be useful at the dock', letters of interest and free-trial requests are not

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

1. Fifteen dockside calls
$350 · 12 days
Assemble 40 growers from the VMRC lease list, the ECSGA network and the AmericanHort directory; call and email with the script. One founder runs 15 conversations about how they count today, then pitches both asks on the call: the $100 kit reservation and the $1,000 October pilot.
keep going if · 6 of 15 growers ask for the reservation link or the pilot scope
2. Reservation page for the kit
$150 · 10 days
One-page pre-order: $499 starter kit, one reader plus 500 rugged tags, Q2 2027 delivery, $100 fully refundable reservation taken by card. Send it in every call follow-up and ask ECSGA to carry it in the member newsletter.
keep going if · 6 reservations from the first 40 unique visitors
3. Two paid commodity-tag pilots
$1,000 · 14 days
Scope a 60-day counting pilot on one product line using off-the-shelf UHF labels at about 10 cents each and a sub-$500 handheld reader - no custom silicon. Invoice $1,000 up front against a written scope and an October start date; this tests whether counting alone changes decisions before any ASIC exists.
keep going if · 2 growers pay $1,000 up front and put a start date on the calendar

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.

$100

per prospect, refundable

how · A $100 refundable pre-order reservation taken by card on the kit page, backed by a stated delivery quarter - the pre-order fits because these growers already buy equipment direct from vendor sites with their own money and no procurement. The two design pilots are separately invoiced at $1,000 up front against a signed one-page scope. set up: Stripe Invoicing ↗

what it reserves · One kit from the first production run of 25, the $499 launch price locked, and a Q2 2027 delivery slot

refund · Refundable in full at any time until the kit ships, and it counts toward the $499 balance at shipment.

target · 8 reservations from 25 grower conversations within 30 days, plus 2 paid pilots

Go: build it if

8 or more $100 reservations from 25 conversations and both $1,000 pilots paid with start dates on the calendar within 30 days.

Kill: stop if

Fewer than 3 reservations from 25 conversations and no grower pays for a pilot - single-site counting is not worth money, so the network never starts.

outreach message

You count cages and pots by walking the rows, and the shrink only shows up months later at settlement. I'm building a tag-and-reader kit that makes every bag, cage and pot countable with a $200 handheld - tags cheap enough to leave on and lose. Before it ships I'm running two paid 60-day pilots this October using off-the-shelf tags on one real product line. Can I get 20 minutes to see how you count today and whether a pilot fits your operation?

landing page

Count every cage, bag and pot without walking the rows $499 starter kit - one reader and 500 rugged tags; reserve yours for $100, fully refundable until it ships Reserve a kit from the first run of 25

deposit terms

Your $100 reserves one starter kit - a handheld reader plus 500 rugged tags - from the first production run of 25, at the locked launch price of $499, targeted for Q2 2027 delivery. The reservation is fully refundable at any time until your kit ships. At shipment it counts toward the $499 balance.

The idea in full

What: Custom backscatter silicon and a $200 reader that bring item-level tracking to businesses that could never justify RFID: a hardware store, a hatchery, a small distributor. Tagfabric builds the tag ASIC and antenna in-house to hit a one-cent bill of materials, and any reader on the network can identify any member's tag, so a pallet tagged by a supplier stays readable at the shop that receives it. Customers buy a starter kit online, no integrator and no field team.
Why now: The NSF has already funded I-Corps translation work on a marine-adapted RFID and analytics platform for digital inventory management in shellfish aquaculture at roughly $50k, which is the signal that item tracking is now being pushed into low-margin physical sectors; meanwhile Shielded (YC S26) is doing decision intelligence for the world's largest supply chains, leaving the small end of the same problem with no data source at all.
Wedge: first customer and entry point: Shellfish and nursery growers who already lose inventory to guesswork and are the cheapest place to prove a rugged one-cent tag, sold as a 500-tag starter kit direct from the site.
Path to 100x: Global item-level tracking hardware, tags and the software on top is a $10-100B market, and cutting the per-item cost roughly tenfold makes a new category - tracking things nobody tracks today. It is winner-takes-most because tags are only worth applying if downstream readers can see them: every reader sold raises the value of every tag, and the shared read graph across trading partners is the network competitors cannot rebuild from zero.
Ceiling: Existing UHF RFID vendors cut prices enough that the network never gets a running start, leaving Tagfabric a component supplier rather than the standard.
Closest real companies, as the generator saw them: Shielded serves the largest supply chains with decision intelligence and depends on data these businesses do not generate; Bizmark is software for physical-goods companies with no sensing layer; Instanture (graveyard, 2024) tried to manage orders across channels without ever knowing where inventory physically was.
Main risk: The one-cent tag never leaves the lab at yield, and the whole cost-collapse argument disappears.

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
4/5
A one-cent tag ASIC plus shared read graph across trading partners is exactly the compounding network that justifies capital-heavy silicon risk.
Bootstrapper
1/5
Custom backscatter ASIC to a one cent bill of materials is a tape-out scale capital program, nowhere near two founders and three years of nothing.
Operator
1/5
A one-cent tag is worthless until trading partners install readers, so the whole chain has to move before a hatchery sees value.
Technologist
3/5
Custom backscatter ASIC is serious silicon, but the entire thesis rests on a one-cent yield that the card admits may never leave the lab.
Risk
1/5
Capital-heavy custom ASIC with a one-cent bill of materials that must clear yield, three years before revenue, against UHF RFID incumbents who can cut price.
trends
2/5
A $50k NSF I-Corps award carries the entire why-now for a cost-collapse thesis that RFID vendors could have chased any year this decade.
