The 5-Tier OSINT System

Open-source intelligence is not a pile of Google Alerts. It is a structured hierarchy of source types, each with different signal strength, latency, and analytical value. Most people default to whatever shows up in their news feed — press releases, blog posts, product announcements — and call it intelligence. That is Tier 5 at best. The sources that reveal strategy before it becomes public live in Tiers 1 through 3, and almost nobody monitors them systematically. The 5-tier system gives you a prioritized collection framework that puts the highest-value sources at the top of your attention stack.

Tier 1 is job postings. This is the single most underutilized source in competitive intelligence. Companies cannot execute a strategy without hiring for it, and they cannot hire without posting roles. A company that quietly posts five machine learning engineers in Singapore is signaling an AI expansion in APAC six months before any press release. Tier 2 is patents and regulatory filings — SEC filings, patent applications, FCC certifications. These are legally required to be accurate and reveal R&D direction 12 to 18 months ahead of product launches. Tier 3 is earnings calls and investor presentations, where executives are legally obligated to discuss strategy with unusual candor.

1. Tier 1: Job Postings Highest predictive value. Roles reveal capabilities being built. Locations reveal market expansion. Seniority reveals strategic priority. A VP hire means a new business unit. Ten engineers mean a product build. Monitor LinkedIn, Indeed, and company career pages weekly.
2. Tier 2: Patents & Filings Legal documents with enforced accuracy. Patent applications reveal R&D direction. SEC 10-K filings reveal risk factors and strategic priorities. FCC certifications reveal hardware products before announcement. Check quarterly.
3. Tier 3: Earnings Calls Executives speaking under legal scrutiny. The prepared remarks are polished messaging. The Q&A section is where real information emerges — analysts ask pointed questions and executives cannot lie. Transcripts are free on Seeking Alpha and company investor relations pages.
4. Tier 4: Digital Footprint Website changes, pricing page updates, technology stack changes (detectable via BuiltWith or Wappalyzer), GitHub repository activity, app store updates. These are operational signals that reveal execution, not just intent.
5. Tier 5: Community Signals News articles, blog posts, social media, conference presentations, podcast appearances, customer reviews. High volume, low signal density. Useful for context and sentiment, but rarely for prediction. This is where most people start and stop — which is why they miss everything in Tiers 1 through 4.
