A customer calls your contact centre and the agent greets them by name — then asks them to repeat information they already provided twice on your website and app. The agent is using one system. The website used another. The app used a third. The customer experience reveals the architectural truth: the organisation has data about this customer, but no unified view of who they are and what they need right now.
Customer Data Platforms (CDPs) solve this problem by creating a persistent, unified customer profile that aggregates data from every interaction across every channel and makes it available in real time to every system that serves the customer — marketing, sales, service, product.
The core CDP capability is identity resolution: connecting the same individual's interactions across different contexts — email, mobile app, web browser, contact centre, physical store — into a single profile, even when the connecting information varies (sometimes an email address, sometimes a phone number, sometimes a cookie). A CDP's match rate — the percentage of interactions successfully attributed to a known customer — determines the completeness and accuracy of the unified profile.
The profiles a CDP creates are the foundation for personalisation at scale. A marketing platform that can access a customer's full interaction history — what they browsed, what they bought, what support issues they raised, what communications they responded to — can personalise messaging in ways that generic segment-based marketing cannot. A service agent who sees a unified view of the customer's relationship with the company can resolve issues faster and more empathetically.
CDPs from Segment, mParticle, Treasure Data, and Adobe Real-Time CDP serve different enterprise segments. For Indian enterprises building their CDP capability, the integration between offline and online data — connecting in-store transactions, call centre records, and WhatsApp interactions with web and app behaviour — is the distinctive challenge of the Indian market, where customer journeys frequently cross digital-physical boundaries.
