What SB Sentinel is
A free morning briefing on AI, security and infrastructure — Five stories, in plain English, every day at 8:00 AM MT.
Last updated: 14 October 2026
The short version
SB Sentinel is a morning briefing. Every day we read the day’s reporting on AI, security and infrastructure, and we pick the Five stories that actually matter. Each one is written out in plain English — no jargon, no acronym soup, no paragraphs you have to read twice. Five stories, five minutes.
It arrives at 8:00 AM MT, free, whether or not you pay for anything. If you only read one email about this industry today, this is the one we want it to be.
How the daily brief is built
We start with the day’s reporting: news wires, company announcements, security advisories, filings, and the technical write-ups that explain what actually happened. Out of all of that we choose Five items — the ones with real consequences, not the ones with the loudest headlines.
Each story is then written the same way: what happened, in one clear paragraph, and why it matters to you, in another. If we cannot explain a story plainly, we leave it out rather than pad the brief with something we do not understand.
The brief goes out at 8:00 AM MT. When we get something wrong, we correct it in the open — the policy is set out on the corrections page.
Who presents it
There is one presenter: Sunny. No rotating cast, no guest hosts, no voice that changes from week to week. You will hear the same person every morning, which is the point — a briefing is a habit, and a habit needs a voice you recognise.
How it is funded
SB Sentinel is subscriber-supported. The daily brief is free, and readers who want more — every story, the archive, the morning video — pay for the Full Brief. That subscription is the revenue.
Which means nobody pays us to say something, and nobody pays us to leave something out. There is no advertiser to keep happy. The brief answers to the people reading it.
How to get in touch
Write to sunny@sbsentinel.live. It is the address we read every morning. If your message is about something other than a correction — a question, or a story we should be covering — say so in the subject line and it reaches the same small team.
