PersonaBox

For Product Marketing Managers

A PMM assistant for the team of one

You only have bandwidth for tier 1 launches, but the product keeps shipping. PersonaBox surfaces the features worth talking about, then drafts the product newsletter, the What’s New update, and the social posts with the messaging you already built.

What we hear from PMMs

The job is bigger than the week

You only have bandwidth for one big launch a quarter

You’re the only PMM. You also own positioning, sales enablement, partner announcements, and the launch calendar. The product newsletter and the What’s New page keep sliding to next month.

You spend hours hunting for what shipped

Slack threads, Gong calls, Jira tickets, then pinging product and engineering to confirm what’s customer-facing. Half a day before you’ve written a single word.

Your messaging brief lives in a doc no one opens

You wrote the personas and the value props months ago. Now the launch deck says one thing, the blog says another, and sales says a third. The messaging you toiled over isn’t the messaging anyone’s actually using.

You’re skeptical of AI writing tools

You’ve seen ChatGPT wrappers that pump out em dashes and AI tells. You care about word choice. A tool that gets you to 70% of a real draft is useful. A tool that hallucinates features and ignores your voice is worse than starting from a blank page.

What changes

A second PMM, on every feature your team ships

PersonaBox is built to give you a real starting point, not a finished post. The drafts come framed for the right persona, in the voice you set, against the rules you wrote.

Finds the features worth talking about

PersonaBox watches your codebase and surfaces the marketing-worthy code changes. No more digging through Slack threads, Gong calls, and Jira tickets to figure out what shipped. You open the dashboard and the list is already there.

Drafts in the messaging you already built

Bring your personas, value props, and brand voice over once. PersonaBox uses them on every draft, so the newsletter, the What’s New update, and the social post all sound like the same company. The messaging you toiled over finally gets used.

Every draft passes your rules

Banned phrases, em dash bans, terminology rules, formatting limits. Define the guardrails once and PersonaBox checks every draft against them before you see it. You spend your edit time on positioning, not on policing AI tells.

A first draft, not a finished post

PersonaBox writes the draft. You review, refine, and ship. Edit by chat to tighten an intro, swap an example, or change the framing for a persona. Every word that goes out still gets your sign-off.
