Identity resolution for the rest of us

Know your customer across every screen

Drop-in SDKs that stitch anonymous users across your app, website, and WebViews into a single unified profile. Resolved data lands in your warehouse.

The Problem

To your analytics, one person looks like four

When a user switches from your website to your app to an in-app WebView, every tool sees a different person. You're retargeting customers you already converted, inflating user counts, and flying blind on cross-platform funnels.

Without CrossTrack

visitor: anon_8f2k

Mobile App

In-App WebView

After Login

= 4 separate people in your analytics

With CrossTrack

John Smith
john@co.com
3 devices · 47 events · first seen 14 days ago

web: anon_8f2k

app: dev_x9m2

webview: anon_p3wv

= 1 real person, full journey

Wasted ad spend

Retargeting users you already converted because you don't know they're the same person.

Broken funnels

Cross-platform journeys look like drop-offs because sessions aren't connected.

Inflated user counts

One person on 3 devices = 3 "unique users" in your dashboard.

Blind support teams

No context on what the user just did in the app when they call support.

How It Works

Three lines of code. One unified identity.

Drop in our SDK on each platform. We handle the identity resolution, profile merging, and warehouse delivery automatically.

Integrate the SDKs

Add our lightweight Web SDK (3 KB), Android SDK, or iOS SDK. Each generates a persistent visitor ID and sends events to our API. Takes minutes, not months.

We resolve identity

Our identity graph links sessions across platforms using deterministic matching, login events, and our WebView bridge — which stitches app and web sessions without requiring a login.

Query in your warehouse

Resolved events with a unified profile_id land in your data warehouse. Query with SQL, visualize in Looker or Metabase. Your data, your infrastructure.

-- All under ONE profile. No stitching needed.

Key Differentiator

The WebView bridge that nobody else does

When a user taps a link in your app that opens a WebView, our SDK automatically bridges the app and web sessions. No login required. This is what Celebrus charges enterprise money for.

🔗

WebView Bridge

App SDK injects device ID into WebView. Web SDK picks it up. Sessions merge instantly. Zero user friction.

👤

Login Merge

When the same user logs in on multiple platforms, all anonymous sessions retroactively unify into one profile.

🌐

Cross-Domain

URL decoration carries identity across different web domains. One person, no matter how many sites.

🔒

Privacy-First

Three-state consent baked into every SDK. Nothing tracks until your user says yes. GDPR-ready from day one.

🏭

Warehouse-Native

Resolved data lands directly in your BigQuery or Snowflake. Your data, your infrastructure.

🛡

Zero Customer Data Stored

We never see or store your customers' personal data. CrossTrack works with hashed identifiers only — we resolve identity without touching the underlying data.

⚡

Lightweight SDKs

Web SDK is 3 KB. Native Android (Kotlin) and iOS (Swift) SDKs. No bloat, no performance impact, no tag manager needed.

Why CrossTrack

Built for the gap in the market

Enterprise tools solve identity but cost $100k+/yr. Developer tools are affordable but treat identity as an afterthought. We fill the gap.

vs Celebrus

Same identity stitching. 1/100th the cost.

Celebrus requires on-prem deployment, months of setup, and six-figure contracts. We're SaaS, self-serve, and integrate in a day.

vs Segment

We solve the one thing Segment can't.

Segment routes events to 300+ tools but its identity resolution is basic — no WebView bridge, no real cross-platform stitching. We complement Segment, not compete with it.

vs Building In-House

Months of engineering, or a 10-minute SDK install.

Identity resolution looks simple until you hit edge cases: cascade merges, shared emails, WebView sessions, returning visitors. We've solved them all.

Pricing

Pay per resolved profile, not per event

A resolved profile is a unique person in your identity graph that had at least one event this month. Predictable pricing that scales with your actual user base.

What is CrossTrack?

The plain English version

No jargon. No technical terms. Just what it does and why it matters.

The short version

CrossTrack helps businesses see that a customer on their website and the same customer on their app is actually the same person.

The problem

Most companies have a website and an app.

When someone visits the website on their laptop, the website says "new visitor!" and gives them an ID. Then that same person opens the app on their phone, and the app says "new visitor!" and gives them a different ID.

Now the company thinks they have two customers. But it's one person. Multiply that across thousands of customers, and suddenly a company thinks they have 500,000 users when they really have 300,000.

Why that's a big deal

Wasted ad spend Showing ads to people who already bought something on a different device

Bad product decisions Thinking features aren't popular when you just can't see the full picture

Wrong numbers Telling investors you have way more users than you actually do

Blind support team Can't see what the customer did in the app when they call in

What CrossTrack does about it

CrossTrack is a small piece of software that companies add to their website and app. It connects the dots automatically — so when the same person uses both, the company knows it's one person, not two. No extra work for the customer. They don't have to log in or do anything special. It just works in the background.

Who needs this?

Any company that has both a website and a mobile app and cares about knowing who their customers actually are.

Online store + shopping app

Fintech
Website + mobile banking app

SaaS
Web dashboard + mobile app

Media

Important: what CrossTrack is not

CrossTrack is not an analytics platform. We don't replace Google Analytics, Mixpanel, Amplitude, or whatever you're already using. We sit underneath those tools.

Think of it this way: your analytics tools tell you what happened. CrossTrack tells them who it happened to — accurately, across every device.

We also don't store your customer data. CrossTrack resolves identity and passes the unified profile ID through to your existing tools and data warehouse. Your data stays yours.

Works alongside what you already use: Google Analytics, Mixpanel, Amplitude, Segment, PostHog, BigQuery, Snowflake, Redshift, Looker, Metabase — CrossTrack feeds accurate identity into all of them.

"You know how companies with a website and an app accidentally count the same customer two or three times? That messes up everything — their ads, their data, their growth numbers. CrossTrack fixes that. One customer = one profile, automatically."
