We have not published a price for Grapevine yet, and we will not invent one. Every tool in every weekday issue is priced for a 20-person product org — the plan a seat, SSO or retention minimum really forces you onto, and the annual dollar figure that comes with it — and that number is published free on this page the morning it is written.
Grapevine — Grapevine indexes Slack, Google Drive, Linear and your codebase, then answers company-specific questions in Slack with citations.
Why it matters for PMsTurns the repeated 'why does this behave this way' questions in your product channel into answered threads you never have to triage.

A complete Adoption Brief, unredacted
This is the whole of one brief as subscribers receive it: the verdict, the one sentence behind it, the price a 20-person product org really lands on, the SSO, SOC 2 and data-handling line, and the three lines you can paste into #product. It is from issue #028, which is already published in full — nothing here is withheld, and nothing is being given away that you could not already read.

Miro for Product Acceleration
Miro's new product suite puts AI agents on the canvas to turn research, sticky notes and sessions into briefs, specs and prioritised backlogs.
Why it matters for PMsIt changes the week after a discovery workshop: synthesis and the first draft of the brief come out of the board instead of your calendar.
Cheap enough to test at $4,800 a year, but the AI value depends entirely on whether your discovery actually happens on a Miro board.
Real price for a 20-person product org
Business plan, not Starter: SAML SSO starts at Business per Miro's plan comparison. 20 members at $20/member/month billed annually = $4,800/year, plus the Miro AI add-on if credit limits bite. SCIM provisioning and data-governance controls require Enterprise, which is quote-only with a roughly 30-seat minimum.
Integration & data risk
SAML SSO on Business, SCIM only on Enterprise; SOC 2 Type II and ISO 27001 published on Miro's trust page; boards and AI prompts sit in Miro's cloud with LLM sub-processors, and Miro states customer content is not used to train models.
Paste this into #product
Proposing we trial Miro for Product Acceleration as the home for discovery workshops, so synthesis and the first brief draft come off the board itself.
Today a workshop costs us two to three days of manual sticky sorting and writing afterwards; this collapses that into a reviewable draft the same day.
Ask: one squad, two discovery sessions, one PM owning the board template, four weeks, then we compare brief quality against our last two.

$490/year
unlimited readers · one organisation · one invoice · paid once for 12 months
Your PMs, your designer and your EM all read the same brief before standup. A Desk Licence covers every reader at one organisation on one invoice — no seat count to pick, no seat admin, nobody to remove when a PM leaves.
Against the $96/year plan it breaks even at five readers: $490/year for the licence against $480 for five annual subscriptions. From the sixth reader on it is the cheaper of the two, and the tenth and fortieth cost nothing more.
We re-read 46 vendor pricing pages every morning — 45 tools, 71 published figures — and diff them against the figures we published.
