What exactly arrives, and when?
One email every weekday morning at 7am. Five AI tools, each with a one-sentence description, a line on why it matters for PMs, and a link — plus, for subscribers, the Adoption Brief on each tool: a one-word verdict, the real price for a 20-person product org, the SSO and data-risk line, and a 3-line pitch for #product. Weekends off.
What's free and what's paid?
The five tools and their three lines are free forever — published on this page, at /today, in the archive and on a page per tool, with no email wall. The decision layer is the paid half: verdict, real price, integration and data risk, and the paste-ready pitch. One complete example is published at /adoption-brief.
Whose price is “the real price”?
A 20-person product org's. Not the headline tier on the vendor's pricing page — the plan you actually land on once SSO, retention or seat minimums are in play, with the annual figure or range, and 'pricing on request' where the vendor publishes nothing rather than an invented number.
Are these tools actually new?
Each issue is researched fresh — recently launched or newly relevant tools, checked against a live web search. You won't get the same five household names every week.
How is this different from an AI newsletter I already get?
Most bundle news, opinion, funding rounds, and a sponsor block. Signal Brief carries five tools and their PM-relevant use case. No essay, no news, no ads.
Who is it for?
Product managers at B2B SaaS companies. The why-it-matters line is written for someone who owns a roadmap and has to justify what they ship — not for engineers or founders generally.
Can I see the paid part before paying?
Yes. One complete Adoption Brief — all five tools of a real issue, with verdicts, prices, risk lines and pitches — is published at /adoption-brief. Every free issue is published in full at /issues, and the field at the top of this page mails you this morning's five tools with no card.
What happens during the 7-issue trial?
You get every issue exactly as a paying subscriber does — five new tools AND the Adoption Brief on all five — for 7 weekday issues. No card is taken, so nothing renews and there is nothing to cancel: after the 7th issue you simply keep getting the five tools free, and $10/month (or $96/year once) keeps the briefs coming. If you would rather put a card on file now, either plan also starts with 7 free days and is not charged until day 8.
Do you still sell teardowns, verdicts or bespoke briefs?
No. Those one-off consulting artifacts are retired — the newsletter is the only thing this business sells. The samples and the verdict library stay published, free, as a record of the work.
How do I cancel?
Reply to any issue, or email [email protected], and we'll cancel it the same day. No retention flow, no "are you sure" maze.
