AppsFlyer is transforming performance marketing with autonomous AI agents that go beyond "chat helpers" — becoming capable teammates powered by BigQuery, Dataplex, Vertex AI, and Agent Engine. To ensure agents act safely and effectively, AppsFlyer built a novel Google Cloud-native data platform: ingesting 200B+ daily signals, proactive quality monitoring, and a custom dynamic metadata control plane that gives agents access to clean, well-curated data with rich context.
