Telecom AdTech Platform

• Disjointed systems: Existing digital screens and applications operated in silos, lacking a unified management and reporting layer.
• Manual operations: Campaign scheduling, ad approvals, and reporting were manually executed, delaying go-live cycles and reducing efficiency.
• Device management complexity: Managing and monitoring thousands of connected screens required centralized control for uptime tracking and issue resolution.
• Scalability needs: The ad playback data pipeline had to support a rapidly expanding fleet of 16,000+ devices across geographies.
• Limited observability: Inconsistent telemetry and performance metrics from devices hindered proactive maintenance and operational reliability.
• Lack of contextual adaptation: Ads could not dynamically adjust to contextual factors such as location or time-of-day, impacting engagement and relevance.
• Isolated analytics: Fragmented data and analytics systems prevented unified visibility into impressions, reach, and ad spend, limiting campaign optimization.

We engineered an end-to-end AdTech platform that unifies CRM, CMS, and ad delivery systems to automate and optimize DOOH advertising campaigns.
