About Attain
Built for privacy — with visibility across all retailers, verticals and purchases — Attain provides solutions for the modern marketer. Its real-time measurement and optimization solutions coupled with high-fidelity audiences and proprietary insights enable marketers to drive valuable business outcomes.
The power of transaction-based audiences
Attain’s real-time transaction data provides a 360-degree view of consumer behavior. What makes this approach more effective than traditional demographic or behavioral targeting?
Attain is the industry’s most trusted source of live purchase data, powered by a robust panel of 8 million fully permissioned consumers. Our platform delivers unmatched, real-time visibility into consumer purchase behavior across retailers, industries, and payment methods. Marketers gain deep insights — such as in-store vs. online purchases, payment methods, purchase frequency, cart contents, and average transaction value — enabling more precise audience targeting and media strategies. With Attain’s rich, transaction-based data, marketers can optimize campaigns with direct, actionable sales signals.
Ensuring data accuracy and relevance
Attain curates audiences using real-time transaction data, but advertisers often ask whether this data is deterministic or probabilistic. Can you clarify your methodology, and if probabilistic, how do you ensure accuracy and representation across the entire US population?
Our transaction data comes directly from the largest live purchase data panel in the U.S. Covering over 10,000+ merchants and $600B in cumulative spend, our dataset offers a complete and dynamic view of real-world purchase behavior. Using advanced machine learning, we scale this data to represent the entire U.S. population with unmatched accuracy, ensuring a balanced and unbiased reflection of consumer spending patterns. Our rigorous methodology eliminates outliers, continuously optimizing for precision and stability, so marketers can trust our insights for better targeting, measurement, and optimization.
Privacy-first data practices
Attain is built on a privacy-first, consumer-permissioned model. There are many ways to capture purchase data—why did Attain choose a panel-based approach, and how does this method compare to other collection strategies in terms of accuracy, scale, and compliance?
Attain’s panel-based approach is the foundation of our privacy-first, consumer-permissioned model. By capturing real-time transaction data directly from our opted-in consumer panel, we ensure unmatched accuracy and ethical data sourcing — paramount in today’s privacy-conscious world.
In exchange for sharing their data, consumers receive valuable benefits like early wages, savings tools, and shopping rewards, with no hidden fees. Unlike legacy third party data providers, our directly sourced transaction data provides deeper, more precise insights, enabling highly granular and actionable audience segments.
Our continuously growing panel reflects a broad cross-section of U.S. consumers while maintaining strict privacy and compliance standards. We fully adhere to regulations like CCPA and GDPR, giving both consumers and advertisers confidence in the responsible use of data. Attain’s approach delivers the ideal balance of accuracy, scale, and compliance—while prioritizing consumer trust.
Cross-channel addressability
With brands activating audiences across display, mobile, and CTV, how does Attain’s purchase data help advertisers refine their cross-channel strategies?
Attain’s purchase data empowers advertisers to refine cross-channel strategies with smarter, data-driven insights. Our real-time transaction-based audiences enable scalable activation across display, social, online video, and addressable TV — ensuring campaigns reach high-intent buyers more likely to convert.
By applying purchase-based audiences across all channels, marketers are utilizing the strongest signals possible, which enables a more effective holistic strategy to drive to that ultimate sales outcome. Whether through social media, TV/CTV, mobile, or programmatic platforms, Attain helps brands connect with consumers at key moments in their buying journey, maximizing media impact with real behavioral insights instead of proxies.
With an expansive and growing network of media partners, Attain ensures brands reach their audiences wherever they are, delivering consistent, high-impact messaging. Whether optimizing for brand awareness or performance, our data helps marketers make smarter decisions to drive superior results.
Proven performance with live purchase feedback
Attain moves beyond traditional proxy metrics by providing live purchase data. How does this help advertisers optimize campaigns while they’re still running?
What sets Attain’s audiences apart isn’t just the data fidelity and holistic coverage of consumer behavior, it’s that they’re built and validated using live, privacy-safe purchase signals. Advertisers can execute campaigns confidently, knowing that they’re reaching real consumers based on recent, real-world transactions, not outdated models or inferred, probabilistic behaviors.
Attain’s ability to measure sales lift across a wide range of inputs means that marketers can easily understand which audiences are driving actual sales outcomes during flight. This unlocks smarter mid-campaign optimizations, discovering new audiences, and fine-tuning targeting — to ensure audience performance continually improves against real revenue goals.
Attain’s closed-loop approach gives advertisers a faster path from targeting to transaction, helping brands maximize the value of every impression.
Industry-specific use cases
Beyond CPG, Attain supports industries like QSR, retail, and financial services. Can you share a compelling example of how brands in these verticals are utilizing your audiences?
Attain’s audiences provide a comprehensive view of the consumer, capturing all aspects of their purchase behaviors — from travel and dining to TV content consumption and shopping habits. This broad perspective offers brands a far richer set of buying signals than ever before, enabling them to make more informed decisions across the entire consumer journey.
- Quick service restaurants (QSR): With a comprehensive view across all transaction types (cash, credit, debit) – Attain enables QSRs to capture a full picture of customer spend at their nationwide locations. Ensuring these brands have holistic coverage across all sales channels, powered by a direct relationship with the consumer, Attain captures transactions both in-store, online, and through 3P delivery apps like UberEats and Grubhub. This powers Attain’s deep insights, which QSRs can use for intelligent, precise targeting- including frequent visitors, competitive share, products purchased, and more. QSRs can use this data to solve a variety of business objectives, like retention/growth, competitive conquesting, and more.
- Retail: In retail, Attain provides a wide range of audience segments, including loyalty shoppers, in-market buyers, competitive shoppers, and even adjacent buyers who may be interested in similar products. By combining these segments, retailers can optimize their campaigns to target real-time shoppers with the highest intent, rather than relying on outdated or generalized profiles that other providers might offer. Additionally, with our industry-leading refresh rate, brands benefit from the most up-to-date data, ensuring their campaigns are always aligned with the latest consumer behaviors.
- Financial services: In the financial services sector, Attain’s purchase data helps identify consumers who are actively considering financial products such as credit cards or loans. By understanding their purchasing behaviors, marketers can deliver highly personalized and relevant offers to those already displaying intent, leading to better conversion rates and more effective acquisition strategies.
Integration with Experian’s marketplace
Attain is now available through the Experian marketplace. How does this integration make it easier for advertisers to activate and scale your audiences?
Attain’s integration with Experian marketplace makes it easier than ever for advertisers to activate our purchase-based audiences across TV, social, and programmatic. This partnership makes Attain’s data even more accessible, supporting our mission to build the most comprehensive and trusted consumer data ecosystem.
With direct access to our real-time audiences within Experian’s marketplace, advertisers can more efficiently launch campaigns at scale and make more precise, data-driven decisions. As one of Experian’s inaugural partners, we’ve already seen strong adoption and demand, reinforcing the value of this partnership.
The future of transaction-based targeting
As the use of transaction data in advertising continues to grow, what changes do you anticipate in how brands will apply it for targeting and measurement? And how is Attain evolving its approach to support those shifts?
As transaction data reshapes advertising, brands can shift from targeting probabilistic audiences to reaching high-intent consumers for greater ad relevance and conversions. Purchase data also unlocks highly accurate incrementality measurement, closing the loop and revealing which tactics and channels drive true incremental sales.
Attain’s platform is built for outcomes-driven advertising, capturing data across the entire media cycle to continuously optimize performance. As we continue to make investments in AI and machine learning into our platform, our insights will become even more actionable and efficient — helping brands maximize impact, drive incrementality, and fuel long-term growth.

"Twine is a respected player in the onboarding space", said Chris Feo, SVP of Global Data Licensing and Strategic Partnerships at Tapad.

At the core of one-to-one marketing and true personalization is identity resolution. For marketers, the ability to accurately and safely connect customer activity across desktop/laptop, mobile, CTV, tablets, as well as CRM and offline touchpoints is ultimately what enables informed and personalized future conversations with each customer. Tapad is known for the precision, accuracy, and scale of their cross device connections, setting them up as an ideal partner for Twine’s TrueData deterministic identity graph. “We believe that by combining Tapad’s renowned cross-device connectivity and our deterministic identity graph, marketers will finally be able to seamlessly segment users based on digital and offline behaviors as well as easily distribute those audiences to both DMP and DSP environments for personalized messaging,” said Elliott Easterling, CEO of Twine Data. With this partnership, Tapad will build a client's cross-device graph off of identities onboarded by Twine from a client's offline CRM. The resulting identity graph can either be delivered directly to brands looking to host their own identity graph, or can be leveraged in a managed fashion for marketers looking for simple connectivity of their offline CRM audiences to their DSPs. To date, Twine & Tapad have seen full connectivity rates* for CRM segments from advertisers at between 259 percent and 322 percent at major DSPs. *Full Connectivity Rate is defined as {total unique desktop, laptop, and mobile devices active at DSP} / {unique CRM users in original audience post cleansing}.

Marketers Using Centro’s DSP Basis Can Leverage Tapad’s Technology for Extended Cross-device Reach Chicago – May 15, 2018 – Centro, a provider of enterprise-class software for digital advertising, today announced that its Basis programmatic ad platform has licensed cross-device marketing technology from Tapad, a part of Experian, the company reinventing personalization for the modern marketer. Media professionals using Basis can now drive better performance by identifying a person across the different devices he or she uses, serving ads in the most optimum environment, then analyzing performance to see what ad worked best based on creative, device, location and time of day. Today’s digital media ecosystem is fragmented. People consume content on their multiple devices from multiple locations. According to digital analytics firm GlobalWebIndex, a typical consumer owns three digital devices and has seven digital ID’s active in the last 60 days. Advertising technology that treats every device as a single user would not be able to guide customers down the marketing funnel according to how users jump from one device to the next. Furthermore, they wouldn’t see when conversions occur on a device different from that in which the ad was first shown to the user. The Tapad Graph identifies the point of conversion across all screens – smartphones, tablets, home computers, and smart TVs – so that marketers can better gauge the efficiency and return on ad spend. “Our technology helps brands gain a deeper level of understanding of their customer, enabling marketers to better deliver services and products users want,” said Chris Feo, SVP of Global Data Licensing and Strategic Partnerships, Tapad. “With our technology as part of Basis, Centro is providing robust, accessible tools for marketers that want to advance their knowledge of the consumers they want to reach.” Centro’s Basis enables advertisers to plan, buy and analyze real-time bidding (RTB), direct, search and social campaigns in a single platform. It is the only platform that combines all of these elements with cross-device conversion attribution and advanced reporting features in a DSP. With the Tapad Graph integrated into Basis, marketers can now identify consumers across all of their devices during any point of the consumer journey. This can help marketers determine ad spend effectiveness for optimizing campaigns in real-time or for the future. Other cross-device marketing capabilities for Basis users include: Frequency Capping: Apply frequency caps at a unique person-level rather than at a device-level to prevent saturating users with ads and showing them more impressions than desired. Audience extension: Expand the reach of a campaign by learning what other devices a single user may have, then deliver ads to single users’ other devices. Reporting insights: Learn how users interact with ads across their devices. Gain insight about how consumers respond on devices to improve targeting parameters. Conversion attribution: Record conversions on devices different from that in which the ad was displayed to learn the true effectiveness of advertising efforts. “Cross-device analytics and optimization aligns with our vision that converging the different parts of digital media to create a holistic view of campaigns will drive performance,” said Katie Risch, EVP of customer experience, Centro. “Having Tapad’s powerful capability of personalized marketing gives our advertisers high-quality data to cultivate relationships with customers, wherever they are in digital channels.” About Tapad Tapad Inc. is the marketing technology company reinventing personalization for the modern marketer through its identity-driven solutions.

The concept of identity resolution has emerged over the years as a strategic imperative among marketers and technology vendors. A report by Forrester contends that accurately establishing and maintaining customer identity is one of the most perplexing challenges facing marketers today. Customers have footprints in the offline and online worlds and tend to seamlessly transition across various channels and devices – presenting a unique challenge to truly understand who they are. But the ability to stitch these disparate components of information together means marketers can make better decisions and have more meaningful interactions with their customers. And for customers, this means an experience with personalized advertising content more likely to resonate with them. Why should marketers prioritize identity? The ability to accurately identify customers is the most basic prerequisite for marketing analytics, orchestration and execution. As such, it is becoming increasingly important for brands and marketers planning to link together disparate systems of audience insights and engagement to foster a more seamless and personalized omnichannel customer experience. For example, if an advertiser can identify a customer’s interests, as well as how that person prefers to consume information, then the advertiser can create and deliver messaging that will resonate with the customer. However, like most competitive differentiators, the mission critical components to accurately determine an identity reside within the suite of identity management tools at the marketers’ disposal and the expertise required for proper execution – a struggle for most marketers. But when properly implemented, a comprehensive customer identity strategy can be among a brand or marketer’s most valuable and proprietary assets. Where to begin with identity resolution? With the convergence of CRM platform data, cross-channel online touchpoints, offline record linkage management, probabilistic cross-device graphs, and data onboarding—evolving from point solutions to unified platforms—marketers are faced with an increasingly complex set of challenges in addressing and solving for customer identity management. To properly implement from the get go, and to avoid having to bolt on disparate technologies down the road, emerging industry trends and success stories suggest marketers need a neutral technology service provider that can provide each of these solutions via a single, unified platform. A vendor that can build a solid identity management foundation comprised of omni-channel targeting and attribution, cross-device resolution, online-offline linkage management, and data onboarding form the nexus of a cohesive identity strategy, built to last.
