Customer Data Platform (CDP)
Digital Transformation / Customer Data Platform (CDP)

Business challenges

Why Customer Data Platform (CDP) projects fail

01

Customer data exists in 5 systems with no unified view

CRM, website analytics, email platform, support desk, and product database each hold different slices of the customer. Nobody has the full picture. Personalisation at scale is impossible without it.

02

CDP purchased 18 months ago and still not delivering

A CDP licence was acquired. Source connections were partially built. Identity resolution was never completed. The promised unified customer profile was never fully achieved.

03

Personalisation impossible without unified data

Marketing cannot personalise at scale without knowing what a customer has done across every touchpoint. The data exists -- it is fragmented across systems with no reliable way to join it.

04

Data subject rights requests take days to fulfil

GDPR and GDPR/CCPA require a complete picture of what personal data you hold. Scattered customer data across multiple systems makes this impossible to fulfil quickly or accurately.

How it works

Our delivery process

01

Source audit

Map every customer data source -- what it holds, how it identifies customers, volume, freshness, and integration complexity.

02

CDP selection

Select the right platform based on your sources, use cases, volume, compliance requirements, and budget. Documented rationale.

03

Identity resolution design

Design the matching and merge rules that create a single persistent customer identity across all sources.

04

Source integration

Connect all sources with streaming where available, batch sync where not, and data quality validation at every ingestion point.

05

Activation

Connect the CDP to every downstream platform that needs unified data -- email, ads, CRM, personalisation, and analytics.

Success stories

Client results

All case studies

We had customer data in 7 systems. Celumai built the CDP layer that unified them into a single profile within 16 weeks. Our personalisation engine now uses real-time unified profiles. Conversion from personalised campaigns improved by 28% in the first quarter post-activation.

Retail Group

We can now fulfil any data subject access request within 2 hours. Before the CDP, the same task required querying 5 systems separately and took 3 days. Our compliance team describes it as one of the most impactful technology investments we have made.
