Process

From raw filings
to clear signals.

We Collect

SEC filings, congressional disclosures, on-chain data, and proprietary feeds — ingested, normalized, and deduplicated in real time.

We Analyze

Multi-signal scoring, confluence detection, regime classification. Raw filings become actionable intelligence — ranked by conviction.

You Act

Dashboards, REST API, MCP tools — consume signals however you build. From manual research to fully autonomous AI agents.

Confluence Engine

When signals align,
conviction spikes.

Multiple independent signals pointing the same direction dramatically reduce noise. Our confluence engine scores agreement across all data sources in real time.
