A decades-old process finally gets a shared surface
DemandTec announced its Co-Planning Calendar on September 22, timed to Groceryshop 2026, describing it as a shared workspace where retailers and CPG suppliers jointly plan promotional events, align funding commitments, and set performance targets against live data instead of email and spreadsheet reconciliation. That framing understates how entrenched the old process actually is across the industry. Trade promotion planning between a retailer's category managers and a CPG's account teams has run on the same basic workflow for decades: a proposal drafted in a spreadsheet, a negotiation conducted over email, and a funding commitment that gets confirmed weeks or months later, if it gets confirmed cleanly at all.
CEO Jack Tirella's diagnosis of why this persisted is the more interesting claim in the announcement. In his own words, every retailer and CPG we talk to has the data, what they don't have is a shared place to decide and act on it together. That points to a coordination failure rather than an analytics failure, and it explains why so many retail data platforms that focused purely on building better forecasting models never actually fixed the underlying friction between trading partners. The forecast, in most of these organizations, was already good enough. The two sides simply never had one persistent, shared record of what had actually been agreed to.
The scale claims are the credibility test
DemandTec is citing real scale to back the launch: roughly 7,800 CPG trade partners, more than 120 retail banners, and 30,000-plus daily users on the existing platform this calendar now extends. That installed base matters because a shared-planning tool is only as useful as the number of counterparties already using it on the other side of the table. A retailer adopting a co-planning surface that its top CPG suppliers haven't already joined has effectively built an island rather than a bridge, no matter how good the underlying software is.
The company also claims 90%-plus demand forecast accuracy on the underlying platform that the Co-Planning Calendar sits on top of. That figure is doing a lot of work in the pitch, but it only closes the loop if the promotional calendar itself, not just the demand forecast, is trustworthy in the first place. A highly accurate forecast built against a promotional calendar full of unconfirmed, tentative commitments still produces a bad operating plan downstream. The Co-Planning Calendar is explicitly trying to fix the calendar's reliability, which is a different and arguably harder problem to solve than forecasting accuracy on its own.
Where the money actually leaks
The financial stakes here are concrete rather than abstract. CPG suppliers fund 40 to 60% of promotional events industry-wide, according to DemandTec's own framing of the problem, and that funding is routinely allocated against historical estimates rather than confirmed, current commitments between the two parties. Every gap between the original estimate and the eventual confirmed commitment is margin leakage that neither the retailer nor the supplier can see clearly until well after the promotion has already run its course, at which point correcting it is no longer possible.
For a retail CFO or CIO, that gap is the actual business case for this category of tool: a shared, live workspace where both parties see the same numbers in real time closes the reconciliation window where that leakage traditionally hides from view. Whether DemandTec's specific implementation delivers on that promise is unproven this early after launch, but the underlying diagnosis of where the money disappears inside a promotional cycle is difficult to argue with given how consistently it shows up across retailer and supplier reporting.
Why this launched at Groceryshop specifically
The timing is not incidental. Groceryshop draws exactly the audience this product needs in one room: grocery and CPG executives who own the trade promotion relationship on both sides of the negotiating table. Launching a shared-workspace product at a conference built around that specific audience is a faster path to the kind of two-sided adoption this tool requires than a traditional enterprise sales cycle would allow, since a retailer and its top three CPG partners can plausibly walk the same show floor and agree to pilot together before they leave Las Vegas.
That go-to-market logic also reveals something about how mature the co-planning category has become. A product built around getting two historically adversarial trading partners to share one calendar only works once both sides have independently concluded that spreadsheet-based reconciliation has become more expensive than the trust-building cost of a shared system. DemandTec's existing scale suggests that threshold has already been crossed for a meaningful share of the grocery and CPG market, which is itself a signal worth noting even for retailers not yet ready to adopt the tool.
The decision this creates for retail technology leaders
This announcement is a useful prompt to audit your own trade promotion workflow, regardless of whether DemandTec ends up being the right vendor for your organization. If your category managers and your top CPG partners are still trading promotion terms over email and reconciling actuals a full quarter later, you are running the exact process this tool is built to replace, and you are almost certainly absorbing avoidable margin leakage as a direct result. The build versus buy calculus favors buying here for all but the very largest retailers, because the value of a shared planning surface depends entirely on your CPG partners already being present on it.
The harder question for 2027 planning is governance: who owns the shared record when a retailer and a supplier disagree about what was actually committed to. Tools like this move the argument from he-said-she-said email threads into a system of record, which is genuine progress, but it also means retailers need clear internal ownership of that system before rolling it out broadly, or the tool simply becomes a faster way to surface disagreements that used to stay conveniently hidden until the quarter closed.
