Agentic investigation platform that queries existing security data stores in natural language

Louie.ai is built by Graphistry, the San Francisco company founded in 2014 by Leo Meyerovich to apply GPU computing and graph analytics to data-intensive investigations. Its customers have historically been large enterprises, technology firms, and federal agencies doing cyber and anti-fraud work. Louie extends that lineage into agentic AI: rather than asking teams to move data into a new lake, it connects to the systems already in place, spanning log platforms, SQL warehouses, graph databases, and vector stores, and derives a semantic layer over them so an analyst can describe an investigation in words instead of writing query syntax for each backend.

Questions produce working artifacts rather than chat transcripts. The platform generates notebooks that mix natural language with the underlying queries, dashboards that can be shared with a wider team, APIs for embedding results into other tooling, and GPU-accelerated graph views for pivoting across entities and relationships. Agents can be defined to carry out repeated triage sequences, so common alert workflows do not need a hand-written playbook for every scenario. Deployment options cover managed cloud, self-hosting in any major public cloud, and on-premises installs including air-gapped environments. Graphistry says the platform has been used to automate Splunk Boss of the SOC exercises and that its team placed first in a U.S. Cyber Command AI competition for alert volume reduction.
