The Problem

Fantasy players juggled multiple websites and social feeds to track injuries and depth chart changes. They needed a trusted, real-time feed that filtered noise and delivered actionable intelligence per roster.

The Challenge

We had to ingest high-volume RSS, social, and beat-reporter content, normalize player entities across leagues, and push alerts within seconds—without overwhelming users or draining device battery.

The Result

Playerline users recorded a 36% win-rate improvement in monitored leagues, daily active sessions doubled season over season, and premium subscriptions grew rapidly through advanced alert tiers.
