Competitive Intelligence

Read your competitor's strategy off public endpoints.

Everything here hits only public, meant-to-be-served endpoints. Robots files, sitemaps, response headers, certificate logs, ad libraries, the Wayback Machine. No logins, no scraping at scale, no decompiling. It is all sitting in the open because someone had to serve it to browsers, to Google, or to regulators. You are just the one who looked.

Each play below is its own chapter. The command-line ones were run live in July 2026, so the numbers are real. Open any of them and you can run it in the next five minutes.

The plays


One line to hold onto. This is recon, not espionage. Every endpoint here is public because someone chose to serve it, and the move is always to use what you find to build something better, never to deceive. There is a quiet bonus in that discipline. In a market drowning in AI slop, the operator who works from real, dated, checkable signals, and shows the receipts, is the one people end up trusting.
