Repeat and customer tiers
Identify your most valuable shoppers—and build strategies to expand them.
The repeat and customer tiers suite helps brands dissect their customer base into precise purchase frequency segments—so you can see exactly who fuels your performance. From shoppers who purchase only once a year to ultra heavy buyers who return five or more times, this capability reveals how each tier contributes to sales, profit, and lifetime value across retailers and channels.

With these insights, your teams can benchmark loyalty behaviors, quantify the revenue concentration among top-tier customers, and spot hidden opportunities to nurture repeat purchasing. Whether you’re designing targeted retention campaigns or optimizing promotional investments, you’ll have clear visibility into the dynamics of customer loyalty and attrition.

This level of granularity helps brands tailor strategies that motivate occasional shoppers to return, while cultivating the advocates who consistently deliver the highest value. Equipped with a data-rich profile of your customer tiers, you can unlock sustained growth by systematically expanding your most committed audiences.

Cross-sell analytics
Know which buyers convert to multi-product loyalists.

The platform compares your cross-sell and upsell performance to any competing brand, providing a clear benchmark of where you lead—and where you lag.

By tracking cross-category buying habits, brands gain a deeper understanding of the factors that drive multi-product loyalty, repeat purchasing, and higher customer lifetime value. Teams can pinpoint the characteristics of shoppers most receptive to new product introductions or promotions, then design targeted strategies to replicate those behaviors at scale.

Retention analytics
Illuminate the full journey of your loyal and lapsed customers across retailers.
The retention module redefines how consumer brands understand loyalty.

Brands can see precisely who returns, who lapses, and who migrates across platforms while staying engaged with your products.

You’ll uncover detailed trends in year-over-year retention and churn—all benchmarked against competitors.

Armed with these insights, teams can design proactive engagement and retention campaigns that meet shoppers where they are—online, in-store, or anywhere in between. By understanding why some audiences remain loyal and others drift away, you gain the strategic clarity to strengthen relationships, protect market share, and grow lifetime value.

Subscription analytics
Uncover the economics behind retailer subscription loyalty programs.

You’ll see which customers are choosing Amazon Subscribe & Save, Chewy Auto Ship, and other subscription programs—and how these cohorts perform compared to competitors.

The platform enables you to measure the economics of subscription retention, track growth over time, and understand the share of your customer base committed to repeat purchasing.

With these insights, brands can optimize investments in subscription loyalty strategies, ensuring resources target the highest-value shoppers. Whether you’re benchmarking performance or refining how you market subscriptions, this module delivers the clarity to design programs that elevate recurring sales and strengthen long-term relationships.

With this intelligence, your teams can quantify incremental sales lift, understand cross-channel shopping journeys, and calculate true ROI across your advertising ecosystem.
