The most influential investors in modern market history.
The Thesis
“Smart money leaves a paper trail. We just read it for you.”
Every fund with >$100M in US equities must disclose their holdings quarterly. Every corporate insider must report trades within 2 business days. The signal is public. The work is parsing it.
How it works
From raw filing to useful insight.
Ingest every filing
We monitor the SEC EDGAR feed continuously. New 13Fs and Form 4s land in your dashboard within minutes.
Parse and normalize
Holdings are mapped to tickers, cross-referenced with prior filings, and deltas are computed automatically.
Surface what changed
You see the signal: new positions, exits, adds, trims — with context and historical perspective.
A quieter way to follow the market
Read the market
like a newsletter.
Your feed learns what you care about — the investors you follow, the sectors you track, the tickers on your watchlist. Everything else stays quiet.
