Limnion

Limnion builds telemetry storage for the agentic era. Its open-source project, Loglake, ingests logs and traces natively over OpenTelemetry, stores them as Parquet and Iceberg on the customer's own object storage and queries them with SQL, as a replacement for systems like Splunk. A managed version runs inside the customer's cloud account, and a detection layer turns raw telemetry into structured incidents that agents can reason about.

Founder Todd Persen previously co-founded InfluxData, the company behind the InfluxDB time-series database, and Era Software.
