No card required to start. Before day 7 ends we email you: keep it for $10/month, or simply walk away — nothing charges automatically, and there is nothing to cancel. Want it now instead of in seven days? The button below charges $10 today — no trial days on it, and you can stop it whenever you want.
Already decided? Pay today instead of trialling.
This is a real charge, not a trial: Stripe takes $10 today, and $10 each month after that until you cancel. Cancel anytime — “Manage subscription” on your account page opens Stripe’s billing portal, and a cancellation takes effect at the end of the period you have already paid for.
Subscribing runs through a Signal Brief account, so if you are not signed in this button takes you to sign in first and returns you to this page. Prefer to look first? The trial button above starts from an email address alone.

Every issue contains exactly 5 new AI tools. Each entry includes a one-sentence description, a line explaining why it matters specifically for B2B SaaS product managers, and a direct link to the tool. 20 issues in the archive, each with 5 new AI tools, a why-it-matters-for-PMs line, and a working link. The newest is #22, published October 12, 2026 — tool 1 of each one is open on its archive page.
Yes — 7 days, and it asks for an email address only. No card is collected, so nothing can charge you automatically: before day 7 ends we email you, and you continue only if you choose to ($10/month). Do nothing and the trial simply ends — there is nothing to cancel. Continuing is a step you take yourself: you sign in and check out in Stripe, and that checkout does take a card. It starts its own 7-day free trial on the $10/month subscription, $10 is charged when those days are up, and $10 each month after that until you cancel from your account page. Your trial unlocks the whole archive on the web — all five tools in every published issue, not just the first. Where that opens: the archive pages themselves show tool 1 to everyone, because they are cached public pages, so your unlocked view is the 'Already a subscriber?' link on any issue page — it renders that same issue whole, every tool, and it follows you to a second phone or laptop through the restore link in your first email. That first email carries one whole edition in full too.
No. Signal Brief has zero sponsorships, zero ads, zero affiliate links, and zero job boards. Every tool is included purely because it's useful for product managers.
No card is collected, so there is nothing to cancel — if all you started was the email trial, it simply ends when the 7 days are up and nothing charges automatically. No invoice, no phone calls, no retention flows. If you did subscribe — you signed in and completed checkout in Stripe, which does hold your card — cancel from your account page: 'Manage subscription' opens Stripe's own billing portal, where it takes a couple of clicks. Your access runs to the end of the period you have already paid for, no further invoice is raised, and your status is re-checked on every visit, so nothing lingers past that date. That page is the 'Your account' link at the top of any archive page. To stop the emails: every email we send carries a one-click unsubscribe link, so leaving the list takes one click and no reply — or write to [email protected] and we will take you off the list ourselves.
