Process

From raw filings
to clear signals.

We Collect

SEC filings, congressional disclosures, on-chain data, and proprietary feeds — ingested, normalized, and deduplicated on scheduled updates.

We Analyze

Multi-signal scoring, confluence detection, regime classification. Compare reported activity across sources for your own research.

You Research

Dashboards, REST API, MCP tools — consume signals however you build. Use the dashboards for research or connect your own tools.

Confluence Engine

Compare sources.
Build your own view.

Compare activity across selected sources and review the underlying records. Confluence is research context, not a prediction of future returns.
