The challenge

Marketplace orders can create customer-data blind spots

When customers purchase through third-party marketplaces, buyer data may be limited, masked, or governed by platform policies. This can make it harder to connect purchases to customer profiles, understand cross-channel attribution, and measure the customer journey.

Ad attribution misses marketplace buyers

Orders placed through marketplaces may not be fully connected to the campaigns that influenced them, making performance measurement and budget decisions harder.

Driving repeat purchases and LTV is harder

Limited visibility means brands may have less insight into repeat buyers across channels, making retention, audience building, welcome, education, cross-sell, and upsell more challenging.

CAC calculation is skewed by missing order data

Without robust visibility into marketplace order attribution, CAC models miss real conversions entirely, making paid channels look less efficient than they are.

The category

Marketplace Identity Resolution, delivered

A new category of customer data infrastructure: turn anonymous, offline marketplace order data into persistent customer records — independent of any channel. Not an export. A database that compounds.

Put Marketplace Data to Work

What can you do with Marketplace X-Ray?

1
true roas

Track conversions and gain true attribution

Connect marketplace and offline orders back to the campaigns that drove them, so paid, email, and analytics finally report on the full picture.

2
one profile
desktopmobilemarketplace

Connect customers across devices and channels

Resolve one shopper's sessions and orders into a single profile — cross-device, cross-browser, cross-channel — instead of fractured and anonymous records.

3
intentsignalcapi

Send unconverted intent to CAPI

Identify high-intent visitors that haven't converted and feed them to Meta through Super CAPI, so the algorithm optimizes on upstream conversion events.

Create a unified customer record

For the first time, create a unified customer record that integrates online store behavior and off-site purchase data. Analyze cohorts you’ve never been able to access, and activate and engage shoppers with more complete multi-channel insight.

The methodology

How does CustomersAI access this data?

Our methodology is built on CustomersAI's broader identity and signal network. It's similar to how companies like Similarweb or Semrush build intelligence from large-scale observed behavioral datasets gathered through browser plug-ins.

Signals in the network
01browser-based observational signals
02commerce intent data
03identity signals
04validation systems
05partner data

We combine data and signals to confidently determine a reachable customer email.

Browser-based observational signals

Real shopping behavior observed across the network — pages viewed, products considered, carts started — the same class of data that powers large-scale commerce intelligence.

Commerce intent and partner data

Purchase and intent signals from our partner network, matched against the marketplace order so we know which shopper the transaction belongs to.

Identity signals and validation systems

Identity resolution plus deliverability validation, so only verified, contactable, compliant profiles ever reach your stack.

No Shopify, Klaviyo or marketplace connection is required for this process.
Validated activation

Built for high-confidence activation, with practical guardrails.

Marketplace X-Ray helps resolve incomplete marketplace order records using identity resolution and validation checks before activation.

Outputs are intended to support measurement and customer-data workflows, subject to platform terms and applicable law:

Server-side conversion measurement
Audience analysis
Suppression and deduplication
Cohort analysis
Lifecycle analysis
High-confidence identity resolution

Profiles are resolved from incomplete order signals and broader identity data, then screened for consistency and quality before use.

Validated before activation

Records are screened and deliverability-checked to improve data quality before use in downstream systems.

Built for policy-aware workflows

Designed to fit into your team's privacy, data-handling, and platform-governance processes, including suppression and opt-out handling where applicable.

Works with your stack

No new tools to learn.
