About Outlier Weekly

A weekly letter on investing and AI. One subject per issue, with the numbers written in the open. This page says who writes it, what it covers, and what it is not.

Who writes it

Outlier Weekly is written by Cemini23, an operator who builds and ships the products behind two of the letters: Atto (youratto.com), a local paperwork kit built around a real Italy packet, and GuruWatcher (guruwatcher.com), an alert-only app that pings Discord when a newsletter's printed price is hit.

The letter started in May 2026 on rare-event markets. It now writes about investing and AI, one subject per issue, plus notes on the products the operator ships. A letter and its hub page do the same job: one claim, the numbers, and a link.

A short history

Outlier Weekly launched in May 2026. Every issue is free to read. The letter has no paywall. As of 12 October 2026 the newest letters are Swarmer, rearmament, and Voyager. Atto and GuruWatcher remain on the same site. The archive is the full list, and RSS carries every issue.

How the letter is made

Each issue picks one subject and writes the numbers in the open. The first market issues used the three-formula system on Methodology. Later issues use the same habit on mines, models, tickets, and products. Product letters do the claim-and-link job for Atto and GuruWatcher: one letter, one owned hub page, one product URL.

Where the letters live

Letters publish on Substack and stay there as the canonical copy: the publication's About page, the Methodology page, the archive, and the RSS feed. This domain, outlierweekly.com, is the owned hub: it links to the letters and hosts the evergreen pages for the letter, how an issue is built, and the tools.
