Carista shifts messaging into high gear and drives 30%+ more sales

Carista gives drivers the power to diagnose, customize, and service their vehicles straight from their smartphones—no shop visit required. By pairing a Bluetooth OBD2 scanner with an intuitive mobile app, they’ve built a loyal, tech-savvy user base of DIYers who want speed, control, and insights on demand. 

To keep those users engaged, Carista needed to communicate with the same level of precision and agility their product delivers. And like many growing apps, they needed to do it without slowing down product velocity or overwhelming their team. 

Whether announcing a time-sensitive sale or rolling out a new feature, Carista needed a faster, more flexible way to reach users. Their existing process for in-app communication slowed them down and lacked the adaptability to serve different messaging needs efficiently. 

Every update required engineering support or an app release, making it harder to move quickly or experiment with new ideas. 

With OneSignal, Carista was able to set up targeted push campaigns, leverage in-app messages without building custom screens, and move fast without being blocked by release cycles. 

The results speak for themselves: 

💥 A single push campaign promoting an app update drove a 31% increase in hardware sales and an 85% month-over-month boost in user reactivations. That one message alone brought 2,000 users to the website and earned a 5.45% click-through rate. 

💥 Another GM-specific offer sent to nearly 4,000 users led to a 19% lift in hardware sales and a 77% increase in GM user reactivations—plus a 5.94% CTR and one-third of that day’s site traffic. 

Today, Carista’s team can launch campaigns that align with product goals, seasonal promotions, or customer needs, without waiting for development cycles or app releases. 

OneSignal transformed push and in-app messaging into a strategic engine for engagement and revenue—one that helps Carista meet users where they are, and in the moments that make or break their bottom line.
