Stocklight
A demand forecasting model any small merchant can self-serve, any app can embed.
Stocklight is a subscription forecasting layer for small merchants who make, move or sell physical goods: connect a store, a POS or a wholesale ledger and get SKU-level demand, reorder points and stockout risk that account for promotions, seasonality and local events.

$700 · 4 weeks · 20 prospects
For $700 and 4 weeks, prove that a $1M-10M specialty food merchant will prepay $199 for a standalone SKU forecast and then actually reorder from it.
Riskiest assumption · A $1M-10M specialty food merchant will pay $199 a month for a standalone forecast today, rather than treat forecasting as a feature and wait for Shopify or Lightspeed to bundle one for free.
1Focus group: who and where
Founder or operations lead of a US specialty food brand doing $1M-10M a year on Shopify or Lightspeed, placing Q4 purchase orders this month while cash sits in SKUs they over-bought last season.
where to find 20 · Specialty Food Association member directory, cross-checked for Shopify storefronts (list); the Shopify Community forum's inventory threads and r/shopify overstock threads (community); reviewers of Inventory Planner and Cogsy on the Shopify App Store, where this exact merchant already complains about bad forecasts (channel).
2Sell first, build later
Founding forecast: connect your Shopify or Lightspeed store and within 14 days get SKU-level reorder points, stockout risk and the cash currently trapped in overstock, refreshed weekly through Q4.
the ask · $199 for the first month, then $149 per month locked for a year for founding members (list price $199 per month)
a real yes · A charged card at checkout is a yes; compliments, requests for a free trial, and 'ping me after the holidays' are not
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Twenty overstock calls
$250 · 12 days
Pull 60 brands from the SFA directory that sell on Shopify, plus named reviewers of Inventory Planner and Cogsy; send the outreach script and book 20 calls. On each call one founder walks the merchant's top 50 SKUs, quotes the $199 prepaid first month, and sends the checkout link while still on the call.
keep going if · 5 of 20 calls end with the merchant taking the checkout link
2. Founding checkout page
$150 · 7 days
Ship a three-line landing page with checkout for the $199 prepaid first month and the $149 founding lock; every call follow-up, forum reply and app-review outreach points to it. No ads - this buyer is reached by name, not by auction.
keep going if · 3 or more paid checkouts from the first 60 unique visitors
3. Deliver and watch the reorder
$300 · 14 days
For the first 3 paying merchants, export sales history and build the SKU-level forecast by hand with off-the-shelf time-series tooling; deliver reorder points and an overstock cash number inside 14 days. Then watch the only signal that beats the free-native-forecast objection: did they place or change a purchase order because of it?
keep going if · 2 of 3 paying merchants place or change a reorder within 14 days of delivery
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.
$199
per prospect, refundable
how · First month prepaid at checkout on the landing page: the merchant pays $199 by card as a founding member. Card checkout fits because a Shopify merchant already buys every tool this way, and prepayment before any model exists is the test itself. set up: Stripe Checkout ↗
what it reserves · One of 10 founding-member slots, the $149 per month price locked for a year, and the first forecast delivered within 14 days of connecting the store
refund · Refunded in full if the first forecast is not delivered within 14 days, or on request at any point in the first 30 days.
target · 5 prepaid checkouts from 20 conversations within 30 days
Go: build it if
5 of 20 merchants prepay $199 within 30 days and at least 2 of the first 3 delivered forecasts cause a real purchase order to be placed or changed within 14 days.
Kill: stop if
Fewer than 2 prepayments from 20 conversations, or 0 of the first 3 paying merchants act on the forecast - either way it is a feature nobody pays for standalone.

The idea in full
- What
- Stocklight is a subscription forecasting layer for small merchants who make, move or sell physical goods: connect a store, a POS or a wholesale ledger and get SKU-level demand, reorder points and stockout risk that account for promotions, seasonality and local events. Under it is a transfer-learned demand model trained across thousands of small catalogs, which is why a merchant with eighteen months of thin history still gets a usable forecast on day one. The same model is exposed as an embeddable API so vertical SaaS vendors, 3PLs and agent builders ship forecasting inside their own products under revenue share.
- Why now
- Booko (YC W26) is pitching dynamic pricing for the whole economy and Bizmark (YC S26) an OS for physical-goods companies, while Smartbase, an AI-native ERP for manufacturers, went dead in 2026: the demand signal is fundable but the full-system-of-record approach is not.
- Wedge: first customer and entry point
- Shopify and Lightspeed merchants doing $1M-10M a year in a single category such as specialty food: self-serve install, one number on the dashboard, cash freed from overstock in the first quarter, $199 a month.
- Path to 100x
- Small-business commerce and inventory software is a $10-100B market, and a forecasting primitive is used by every merchant and every app serving them, so distribution multiplies through partners rather than sales headcount. The moat compounds: every connected catalog improves priors for cold-start merchants, so the accuracy gap over a new entrant widens exactly where small merchants have the least data of their own.
- Ceiling
- Forecasting may be a feature, not a platform, in which case it gets bundled into commerce suites at near-zero price.
- Closest real companies, as the generator saw them
- Booko prices goods dynamically and FeatureBox AI recovers CPG revenue at retail; Stocklight sells the forecast itself as a component rather than a full application, which is why it can be inside a competitor's product instead of against it. Smartbase and Instanture both died selling all-in-one operations suites to the same buyer.
- Main risk
- Commerce platforms ship a good-enough native forecast for free and the embeddable layer loses its reason to exist.
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
Cold-start priors improving with every connected catalog is compounding data, and the embeddable API distributes through partners instead of headcount.
Bootstrapper
3/5
Self-serve $199 a month at software margins is affordable to build, but a free native Shopify forecast collapses the price overnight.
Operator
3/5
Overstock cash is genuinely expensive for a $1M-10M merchant, but at $199 a month forecasting reads as a feature commerce suites will bundle.
Technologist
4/5
Transfer-learned priors across thousands of catalogs give cold-start merchants accuracy a new entrant cannot buy, and the gap widens per connection.
Risk
2/5
Connects through Shopify and Lightspeed, and the card concedes a free native forecast from those same platforms removes its reason to exist.
trends
1/5
Transfer-learned SKU forecasting for Shopify merchants was equally possible in 2023, and a dead ERP competitor is not evidence of an opening window.
