EdgeLetter identifies assumption breaks before they become headlines. Verified lead time. Documented protection events. Measurable reaction time advantage — not AI predictions, not market commentary.
The Free tier is designed to reveal vulnerability. You'll see completed protection events, confirmed outcomes, and measured lead times from events that have already resolved. What you won't receive is the active alert — the reaction time advantage — before it prices in.
Six intelligence verticals. Each surfaces a different class of assumption break. Explore the proof archive for each vertical before subscribing.
Delivered at 05:00 your local time — before pre-market opens. Filtered to your verticals. Ranked by assumption-break severity. Designed as workflow infrastructure, not content.
The Weekly Calibration doesn't summarise what happened. It answers what assumptions failed, which held, and which are currently at risk. Published every Friday. Free tier gets the summary — paid subscribers get the full assumption breakdown before the week closes.

Not AI. Not predictions. Not a newsletter.
A protective intelligence system that measures and documents reaction time before consensus recognition.
