Why Now
2026: You Cannot Afford to Let a Single High-Intent Visitor Leave
Customer Acquisition Cost is at an all-time high.
Paid social CPMs are rising, and organic reach is shrinking.
Every visitor to your retail touchpoint has cost you real money. A static catalogue that fails to respond to their intent is leaving that investment on the table.
CAC at All-Time High
Increasing Customer Lifetime Value and repeat sales is now essential, and can be achieved by significantly improving customer loyalty through deep personalization.
Intent Is Fleeting
The window between interest and abandonment is measured in seconds. Real-time intervention is essential before the moment is gone.
The Responsive Retail Environment
CartTheorem transforms your store from a passive catalog into a live retail environment that acts instantly on every signal of intent.
CartTheorem is not just an app. It is the essential infrastructure for the next era of retail business. Don't fall behind.
The Problem
Marketing Blindness: The Cost of Missed Moments
Most retailers are still trapped in state-driven marketing. They wait for a page to load or a cart to open before acting. By then, the critical moment of intent has already passed.
70%
Carts Abandoned
Most merchants lose 7 out of 10 potential sales.

Lost Revenue Annually
Global commerce revenue lost to cart abandonment.
3-5s
Window of Intent
The fleeting moment between interest and abandonment.
5x
CAC Increase
Acquiring new customers now costs 5x more than 3 years ago—making customer retention and repeat purchases critical for survival.
Loyalty apps like Smile.io build relationships, but can't close a sale right now. Klaviyo fires after the fact. Rebuy checks the cart on load. Every legacy tool reacts to history – not to the live customer. This leads to missed conversions, margin-destroying blanket discounts, and a static retail environment that feels unresponsive.
The Solution
The CartTheorem Solution
CartTheorem offers a powerful, multi-part platform designed to transform your marketing. It empowers merchants to create unlimited personalized promotion strategies by combining targeting signals with various reward types.
These strategies are then delivered in real-time as customers shop. Forget generic algorithms or complex coding – CartTheorem executes your unique strategy at machine speed.
Merchant-Designed Strategy
You define who gets what offer based on customer behavior, loyalty status, browsing activity, and business goals. Build unlimited promotion combinations using your brand knowledge and intuition.
Custom AI Per Merchant
Every store gets a unique AI prediction engine trained exclusively on their own customer data—not generic industry patterns. Your AI engine learns what works for YOUR audience and gets smarter over time.
Multi-Channel Deployment
Deploy your promotion strategies across all retail touchpoints, including physical stores, petro convenience, and AI shopping assistants. One platform, every touchpoint.
The Three-Layer Architecture
01
Core Engine
A no-code promotion builder where merchants design custom offers. Combine targeting signals (demographics, loyalty, browsing, RFM, inventory) with reward types (discounts, points, gifts, shipping, bundles). The permutations are endless, allowing each merchant to create a unique suite of promotions.
02
AI Enhancement
Each merchant receives a unique AI prediction engine. This custom model is trained exclusively on your store's data, learning which customers respond best to which promotions. It optimizes timing and adds surprise elements to maximize customer delight.
03
Multi-Channel Execution
Seamlessly deploy your promotion strategies across all retail platforms (Shopify, WooCommerce, POS systems), physical stores, petro convenience, and AI shopping assistants (via MCP servers). It's one platform covering every customer touchpoint.
This is merchant-first promotion intelligence—you stay in control of strategy, budget, and risk.
CartTheorem executes with precision across thousands of customers in real-time, ensuring maximum impact for your business.
Core Platform
Build High-Impact Personalized Promotions

Customer Perspective
Instantaneous Gratification — The Dopamine Effect
CartTheorem delivers instant, tangible value at the exact moment customers are most engaged. This triggers the same dopamine rush as winning and transforms hesitant shoppers into delighted buyers, closing sales today.
The Customer Journey
01
The Hesitation Moment
Sarah, a Gold tier customer, has $180 of travel gear in her cart. Her cursor hovers over checkout, then drifts. She thinks: "Should I wait for a sale?"
02
The Instant Trigger
A message flashes: "Sarah, we noticed you love travel ✈️ As a Gold member, enjoy an additional 5% off travel products + 100 bonus points—applied instantly to your cart!" No code, no delay. Immediate, personal value.
03
The Dopamine Hit
Sarah is surprised and thrilled. The store gets her, rewarding her loyalty precisely when it matters. Hesitation vanishes. She completes the purchase, feeling delighted, not manipulated.
Why This Works Better
What Doesn't Work
  • Generic 15% off offers (feels impersonal)
  • "Earn points for your next purchase" (delayed gratification misses today's sale)
  • Abandonment offers (often too late)
  • Email follow-ups (customer's attention has moved on)
The CartTheorem Difference
  • Personalized: Based on Sarah's interests and behavior.
  • Rewarded: Acknowledges her loyalty tier and purchase history.
  • Instant: Applied immediately, no friction.
  • Perfect Timing: Delivered at the precise moment of hesitation.
  • Surprise Factor: Unexpected delight strengthens loyalty.
  • Result: Purchase completed, customer loyalty deepened.

This is precision retail psychology—delivering the right reward, to the right person, at the exact micro-moment when it matters most. Generic discounts can't compete with this level of personalization and timing.
