About
The honest planner for Shopify brands.
Inventory is the biggest cash line on a brand’s balance sheet, and most brands under $25M still plan it in spreadsheets and black-box tools they don’t trust. Sellcast is one AI loop that forecasts demand, drafts the buy, scores the promo, and gates the markdown, with every number shown and every action yours to approve.
Buy right, then sell through what you bought.
Why now
The default planner is being switched off.
Shopify retires Stocky, its own free planning app, on August 31, 2026, API included. Tens of thousands of brands are shopping for a planner they can actually trust: one that explains itself and does the work, not another dashboard to re-key into a spreadsheet.
Three shifts make a better answer possible: forecasting has commoditized, AI agents can now draft real actions at SMB prices, and the category’s free anchor is gone. Sellcast is built for that moment.
The thesis, in one line
Most tools help you buy right. Almost none help you sell through what you bought.
Sellcast closes the whole loop (forecast → buy → promote → liquidate) as one system. The forecast drives the buy, your stock position drives the promo, and what won’t sell gets gated for markdown.

Four principles, published on purpose
They’re not a values page. They’re how the product is built, and how you can hold us to it.
Show the work
Every forecast, buy, promo, and markdown opens to the drivers behind it. In a category of black boxes, we earn trust one reconciled number at a time.
You approve every move
The agent drafts; you decide. Nothing executes on its own. The authority envelope defaults to zero, and every action is audit-logged.
Pricing that doesn’t punish growth
Published prices at every tier, monthly always available, no renewal ambush. You should never be surprised by your own bill.
Your data is portable
One-click CSV export, always. We want you to stay because the product earns it, not because leaving is painful.
How it’s built
Founder-led, and heavily AI-leveraged.
Sellcast is a young, founder-led company in early access, and it’s built with the same kind of AI leverage we sell. A small footprint means we ship fast, answer support ourselves, and stay close to the operators we build for.
It also means we’re candid about where we are: the core planning product is built and running; the polish for a public launch (the App Store listing, self-serve onboarding) is in progress. Our roadmap says exactly what’s shipping and what’s next, with no invented history.
