We are working on a Customer Data Platform—a solution that enables companies to efficiently manage end-user data in our new product. Our platform integrates data from various sources (tracking codes, chats, tickets, custom data) and transforms it into a unified customer profile.

Within this platform, the Customer List sub-team focuses on real-time visitor intelligence. We surface valuable, live information about visitors browsing our customers’ websites. Our backend infrastructure handles high-throughput data streams using Kafka and WebSocket pushes, processing over 1 million visitors at peak times.

Our frontend is responsible for consuming thousands of real-time events, transforming them into clear, responsive, and insightful user experiences. Our mission is to tame the stream of live data and make it actionable – delivering the kind of visibility that helps our customers make smart, timely decisions.
