Just launched SignalX on Play Store. Built it solo because I got tired of reading 200-page 10-Ks. AI summaries for 10-K, 10-Q, 8-K, Form 4, 13F. Insider screener. Activist (13D/G) tracker. Chat with your watchlist. 5 free queries/mo. Feedback welcome.

There's something raw about late-night debugging solo - just me, endless logs, and a cold cup of coffee fighting a sneaky bug that refuses to show itself #indiehackers #solofounder Building signal-x.app solo

Nothing beats spotting when insiders buy and big funds hold the same stock - that overlap is where finds its clearest convergence signals. 💡 #fintech #investing signal-x.app

Spent months chasing perfect AI features for before I realized - the best product is the one users can actually start using. Shipping beats tweaking every time #buildinpublic #solofounder Building signal-x.app

Built it because I wanted Korean names sitting next to US filings (13F, 13D) on the same screen. If you track ADRs or foreign holdings into Korea, this fills the gap. Feedback welcome.

Other groups (Hyundai, LG, SK, Lotte, etc.) are Pro. Big groups fan out to 60+ affiliates and ~70 nodes in one view. There's a free 1-month code floating around. Use SX-8KKYTN at checkout. Limited spots.

Just shipped: Korean chaebol ownership graph. Samsung, Hyundai, LG, SK and their affiliates mapped on one screen. Samsung is free. One Google sign-in, that's it. signal-x.app/ownership-graph
