Case Study: K Car achieves 8X increase in customer-journey engagement and 30% MAU growth with Braze

K Car Drives More Successful Customer Journeys and Boosts MAU by 30% With Segmentation

K Car, Korea’s leading online used car trading platform, needed a way to track real‑time customer behavior and turn those insights into highly targeted messaging—something their previous marketing tools couldn’t handle. To solve this, K Car adopted Braze’s customer engagement platform alongside analytics partner Amplitude to enable deeper audience understanding and real‑time campaign activation.

Using Braze (with Amplitude feeding behavioral data), K Car created dynamic audience segments based on app and web activity and sent personalized in‑app messages and push notifications to browsing users to sign up for alerts. With Braze powering the engagement, the campaign drove an 8X increase in users taking the next step in the customer journey and a 30% rise in monthly active users.
