Auto-Monitor SEC Filings and Filter by Investment Thesis
SEC Deal Flow Automation
Most VC and PE firms are still monitoring SEC filings manually. An analyst opens EDGAR, filters by form type, scrolls through hundreds of entries, copies names into a spreadsheet, and repeats this every morning.
This automation eliminates that entirely.
Every weekday at 6AM, the pipeline pulls all new S-1 and Form D filings from SEC EDGAR, runs each company through an AI filter trained on your investment thesis, and delivers two clean reports to your inbox, one with companies that match, one with companies that don't. No manual work. No missed filings. No wasted analyst hours.
What gets automated: Daily SEC EDGAR monitoring (S-1, Form D, or any filing type) , AI-powered thesis filtering (sectors, stage, geography, exclusions) , Structured email report with company name, location, form type, and direct SEC link , Separate matched and excluded lists so nothing gets lost
The result: Your team starts every morning with a pre-filtered deal list instead of a raw data dump. Analysts spend their time on first calls and conviction-building, not filing lookups.
Built on n8n, SEC EDGAR's public API, and OpenRouter. No third-party data subscriptions required.
