StackAdapt yesterday launched its Economic Impact Report, a self-serve measurement tool built directly into its platform that lets advertisers connect ad exposure to consumer spending data while campaigns are still running. The feature draws on permissioned transaction data from Affinity Solutions covering more than 150 million credit and debit cards, and it targets travel marketers, destination organizations, and tourism boards first.

What StackAdapt announced

StackAdapt, the Toronto-based programmatic advertising and orchestration platform, introduced the Economic Impact Report on July 30, 2026. According to the company, the tool is designed to move advertisers past two long-standing habits in campaign measurement: waiting for a campaign to finish before assessing its economic value, and relying on proxy metrics such as clicks or engagement rather than actual spending. The report instead connects media exposure directly to consumer transaction data, with results accessible from within the media buying workflow rather than through a separate reporting process.

The company built the tool for a specific set of advertiser categories. Travel marketers, destination organizations, tourism boards, and brands pursuing location-based objectives sit at the center of the initial rollout, according to the announcement. That focus matters because these categories often answer to public stakeholders or government funders, and they have historically depended on delayed, sample-based economic impact studies to demonstrate the value of marketing spend. A tourism board justifying a regional campaign to a legislature, for instance, would traditionally wait months for a post-campaign report before it could show any return.

Data underpinning the feature comes from Affinity Solutions, a consumer intelligence company that supplies permissioned transaction records. The figures StackAdapt cites are substantial: more than 150 million credit and debit cards, over 100 million consumers, 86 billion transactions, and more than $4 trillion in aggregate spend tracked across more than 5,000 brands. StackAdapt frames that panel as representing roughly 25 percent of the U.S. adult population, giving the underlying sample considerable scale relative to smaller survey-based measurement panels used elsewhere in the industry.

How the measurement mechanism works

The Economic Impact Report operates through what StackAdapt describes as modeled attribution, connecting advertising exposure to aggregated spending behavior rather than tracking individual transactions to individual ad views. Advertisers can measure several distinct outputs once a campaign is configured: total attributed visitor spend, return on ad spend, the number of visitors and transactions generated, and the origin markets responsible for the greatest share of economic value.

That last metric, origin market identification, addresses a specific operational question that travel and destination advertisers frequently face. Rather than simply knowing that a campaign generated visits, a tourism board can see which regions or metro areas are producing the visitors who spend the most once they arrive, data that feeds directly into future budget allocation decisions. This differs from engagement-based reporting, which might show which markets clicked on an ad without indicating whether those clicks converted into actual travel spending.

Configuration, according to the announcement, takes minutes rather than the days or weeks typically associated with commissioning a post-campaign economic impact study. Because the tool sits inside the existing StackAdapt workflow, advertisers do not need to export data to a third-party analyst or wait for a separate vendor engagement to interpret the results. StackAdapt describes the report as fully self-serve, meaning advertisers configure and access it without requiring a managed-service arrangement with the platform.

Statements from StackAdapt and Affinity Solutions

Michael Shang, SVP of Advertising Technologies at StackAdapt, framed the launch around the gap between what marketers have long believed about their campaigns and what they have been able to prove while those campaigns were active. "Marketers have long known their campaigns drive real economic value, but proving that impact has often required waiting until a campaign ends," Shang said, according to the announcement. "With the Economic Impact Report, we're bringing transaction-backed measurement directly into the platform so advertisers can measure business outcomes, optimize campaigns while they're running, and make smarter investment decisions faster."

Kalyan Lanka, Chief Product Officer at Affinity Solutions, addressed the underlying data source and why deterministic transaction records carry particular value when paired with media measurement. "Deterministic credit and debit card transaction data offers a powerful lens into real consumer behavior, but it's most impactful when marketers can connect those insights to media ROI," Lanka said, according to the announcement. "Together with StackAdapt, we're enabling advertisers to move beyond proxy metrics and closed-system reporting by tying media exposure to real-world purchase outcomes. That closed-loop visibility allows brands to measure what happened after media exposure, optimize campaigns in-flight and drive growth."

Neither statement addressed pricing, minimum spend thresholds, or a timeline for expanding the tool to advertiser categories beyond travel, destination, and location-based marketing. The announcement also did not specify whether the underlying Affinity Solutions panel extends outside the United States, where the cited card and consumer figures are based.

Positioning against post-campaign studies and proxy metrics

StackAdapt's announcement repeatedly contrasts the new tool against two alternatives: traditional post-campaign economic studies and engagement-based proxy metrics. Both carry recognized limitations that have shaped measurement debates across the advertising industry over the past year.

Post-campaign studies typically require weeks or months to compile, by which point the media budget in question has already been spent and the campaign has concluded. Any insight the study produces can only inform the next campaign cycle rather than the one being measured. Proxy metrics such as clicks, impressions, or engagement rates, meanwhile, describe delivery and attention rather than economic outcomes; a highly clicked campaign does not necessarily translate into visitor spend or transaction volume.

This tension between delivery metrics and business outcomes has surfaced repeatedly across programmatic advertising measurement announcements throughout 2026. PPC Land documented the industry's broader structural shift toward business outcomes as the primary standard for campaign measurement in January 2026, a trend that StackAdapt's Economic Impact Report extends into the travel and destination marketing category specifically.

Other measurement providers have pursued similar goals through different mechanisms. Cint introduced in-flight outcomes measurement inside its Lucid Measurement platform on June 17, 2026, also drawing on Affinity Solutions transaction data to connect brand lift and sales lift signals within a single live dashboard. That launch addressed what Cint executives described as a fragmented workflow in which brand and sales measurement had historically been handled by separate vendors using separate methodologies. Affinity Solutions' data previously appeared in Innovid's pixel-free purchase attribution platform, announced in June 2025, where the company supplied deterministic data drawn from in-store and online credit and debit card transactions to support attribution without relying on tracking pixels.

The pattern extends into retail media as well. A report from Incremental, covered by PPC Land in June 2026, found that last-touch attribution systematically understates return on ad spend for upper-funnel retail media campaigns, in some cases understating true ROI by a factor of three to five, because upper-funnel spend frequently drives sales at retailers other than the one running the campaign. And in May 2026, an Affinity Solutions report found that marketers estimated wasting roughly 11 percent of media budgets on poor optimization signals, even as three-quarters of the same respondents said they were satisfied with their existing measurement tools - a gap that suggests confidence in measurement systems does not always track their accuracy.

Taken together, these prior reports establish the industry backdrop against which StackAdapt's announcement lands: a sustained push, spanning multiple vendors and measurement categories, to close the distance between when a dollar is spent on media and when an advertiser can see what that dollar produced in actual revenue.

StackAdapt's broader platform context

StackAdapt describes itself as an AI advertising and orchestration platform, unifying programmatic and owned channels including connected TV, digital out-of-home, display, native, audio, and email into what the company calls a single workflow. The Economic Impact Report is not StackAdapt's first move into transaction-linked or location-based measurement. The company launched a footfall attribution solution with Adsquare in September 2024, enabling advertisers to measure customer visits to physical locations following digital ad exposure across EMEA, APAC, North America, and Latin America.

The company has also expanded steadily across data infrastructure and channel partnerships over the past year. StackAdapt unveiled a Snowflake Native App for first-party data activation on July 24, 2025, and launched its Ivy AI assistant on July 9, 2025, which the company said processed more than 1,700 in-platform messages during the 30 days preceding its release. StackAdapt achieved a 71 percent reduction in queries per second through an Index Exchange ad podding integration for streaming television transactions announced on July 1, 2025, and it later integrated iHeartMedia's broadcast radio inventory into its programmatic platform in November 2025.

More recently, the company secured certification under the EU-U.S. Data Privacy Framework on February 7, 2026, a mechanism enabling lawful cross-border transfer of personal data between the European Union and participating U.S. organizations without additional Standard Contractual Clauses. StackAdapt also brought self-serve National Provider Identifier targeting to pharmaceutical advertisers on January 6, 2026, and joined OpenAI's ChatGPT advertising pilot as a technology partner on May 5, 2026, placing it alongside Criteo, Kargo, Adobe, and Pacvue among a small group of platforms with early access to conversational AI ad placements.

Against that backdrop, the Economic Impact Report represents a continuation of a pattern rather than an isolated release: StackAdapt has consistently paired new channel access with new measurement capability, whether through location intelligence, healthcare targeting precision, or now transaction-backed economic reporting for travel and destination marketing.

Why this matters for the marketing community

The travel and tourism sector, where StackAdapt aimed this launch, has been navigating its own measurement pressures independent of any single vendor's product roadmap. Impression's Travel & Tourism Marketing Landscape 2026 report, published March 30, 2026 and covered by PPC Land, found that customer lifetime value analysis, marketing mix modelling, and incrementality testing had emerged as the leading effectiveness measurement tools among UK travel marketers, even as nearly 80 percent of respondents in that survey expected revenue growth over the coming year. That research, drawn from 1,000 UK marketing professionals across airlines, hotels, destination marketing organizations, and other travel categories, signals sustained appetite for more rigorous measurement tools within the category StackAdapt is now targeting with its Economic Impact Report.

For organizations accountable to public funding or stakeholder reporting - a category that includes many tourism boards and destination marketing organizations - the shift toward continuous, transaction-backed measurement carries implications beyond simple campaign optimization. A destination organization funded through public tourism levies or municipal budgets typically must justify its marketing spend to oversight bodies, and a report arriving weeks after a campaign concludes limits how quickly that organization can adjust strategy or defend continued funding. Real-time visibility into visitor spend and origin markets could shorten that reporting cycle considerably, assuming the underlying attribution methodology holds up to scrutiny across a broader set of campaigns than StackAdapt has yet disclosed publicly.

The broader measurement debate that this announcement joins is not settled. Whether modeled attribution built on aggregated transaction panels produces results that hold up against more rigorous causal methods, such as randomized holdout testing, remains a live question across the industry, and StackAdapt's announcement does not address how its methodology handles that distinction. What is clear, based on the pattern of announcements from Cint, Innovid, and now StackAdapt, is that transaction-backed measurement data from providers such as Affinity Solutions has become a recurring foundation for vendors attempting to close the gap between media spend and demonstrated business outcomes - a gap that, according to industry data cited above, may currently be costing advertisers a meaningful share of wasted budget through poor optimization signals.
