CtrlB is an AI-native observability and security intelligence platform built for cloud-scale infrastructure. It replaces legacy inverted indexes and hot storage tiers with probabilistic sparse indexing over a Parquet-on-S3 data fabric, enabling terabyte-scale telemetry ingestion and query at a fraction of the cost of incumbent platforms. Logs, metrics, traces, and security telemetry unify into one analytical surface, giving teams a real-time, correlated view of their environment.
