Editor’s pick

Small‑/micro‑cap **dilution intelligence** platform focused on U.S. listings. Tracks S‑1/S‑3 shelves, ATM programs, convertibles, warrants, reverse splits, and completed offerings; pairs this with PR/SEC wire monitoring and configurable email/SMS alerts. Includes public ‘open‑access’ tickers plus paid tiers. Strong for event‑driven traders (supply/float risk) rather than factor, portfolio, or options‑greeks analytics.
