Case Study: Spark New Zealand achieves real-time personalised marketing at scale with Tealium

From Data Chaos to Autonomous Marketing How Spark New Zealand Scaled Real-Time Personalisation with Tealium, Snowflake, and Kapello

Spark New Zealand, the country’s largest digital services provider, was struggling with a tangle of legacy systems, siloed customer data, and point-to-point integrations that created inconsistent customer experiences across channels. Working with Tealium, the company needed a real-time data foundation to replace slow batch marketing and enable more timely, personalized engagement.

Tealium helped Spark New Zealand rebuild its martech stack with real-time customer data capture, identity resolution, and activation, integrated with Snowflake and its Kapello AI engine. The result was sub-300ms decisioning, event data flowing into Snowflake in under 10 seconds, and enriched traits sent back to Tealium in under a minute. This new approach delivered +22% incremental conversion from next-best-offer decisions, +13% from real-time triggers, and more than 150 million personalized offers each month.
