Monitoring competitor 13D filings is a job, not a hobby.
If you run compliance at a small RIA, VC fund, or family office, you can't afford to find out about a competitor's activist position three days late from a colleague. FilingFirehose tracks every Schedule 13D, 13G, and amendment within 30 seconds of filing.
Sound familiar?
- Manually checking EDGAR for 13D filings on your watchlist tickers eats hours every week.
- sec-api.io is $300+/mo and bundles features you don't need.
- You missed a competitor's 5%+ position because the filing came in on a Friday afternoon.
- You need to flag amendments (13D/A) separately from new filings — most tools don't.
