Event tracking
Streamline data collection and fuel smarter marketing in real time.
Event tracking gives brands the power to capture the full story of each shopper, in every moment, across every touchpoint. Whether a customer browses your product pages, clicks an email, adds an item to their cart, or completes a purchase, our technology records each event with precision and delivers it wherever you need it in real time.

Easily customize what you track and centralize every interaction in your data warehouse—no complex development required. From there, sync events instantly to the platforms that drive your business, including Amazon Ads, Facebook, Google, and your internal analytics tools.

Event data flows continuously to fuel personalized campaigns, inform dynamic product recommendations, and optimize retargeting—all without lag or friction. With a unified view of how shoppers engage, you can uncover new opportunities to improve conversion and retention.

Empower your teams with immediate, reliable data that transforms passive signals into active growth. With real-time event streaming, you’re not just observing shopper behavior—you’re acting on it faster than ever before.

Composable ingestion
Reimagine CDPs with composable architecture and total data ownership.
Composable ingestion transforms how brands unify, secure, and activate their data across every customer touchpoint. Unlike traditional CDPs that duplicate or warehouse your data in opaque systems, our approach allows you to connect directly to your existing infrastructure—so your data never leaves your control.

With just a few lines of code, you can collect any web or server-side event and ingest it seamlessly into your own data warehouse.

Event tracking makes it effortless to centralize information, while our identity resolution lets you define the rules and maintain ownership of your identity graph.

A composable CDP deploys in weeks, not months, and puts your data strategy back where it belongs: in your hands. No replication. No compromises. Just a powerful, secure foundation to orchestrate marketing at scale.

Enrichment
Complete your customer view with enriched data across retailers.
Identity matching
Unify fragmented customer data into rich, actionable profiles that can be activated across all retailers and ad platforms.
Identity matching transforms disconnected, incomplete shopper data into unified, dynamic profiles you can trust. Instead of relying on black-box platforms, you keep full control—stitching identities directly within your data warehouse to create a single source of truth that fuels every channel.

Connect purchase history, browsing behavior, and engagement signals from any source—online, offline, or third-party—into a comprehensive profile of each customer. Whether you’re linking transaction records from Amazon, ad engagements on Google, or loyalty activity from in-store visits, every detail contributes to a richer understanding of your audience.

Flexible matching logic lets you toggle between deterministic and probabilistic resolution depending on the precision and reach you need. From high-confidence targeting to broader lookalike modeling, your teams gain the ability to define and refine profiles for any campaign.

With complete, accurate profiles synced to your marketing stack, you can personalize experiences, optimize messaging, and reach customers wherever they search, scroll, and shop. Identity matching puts you in control of your data—and unlocks the potential to build connections that drive growth.
