The problem we're tackling
Your team spent weeks perfecting persona-based messaging, but when it's time to write, those documents sit unopened in a folder somewhere.
The impact hits GTM outcomes you own:
- Answer engines get your positioning wrong
- Sales emails get ignored and deals slow down
- Webpages and ads drift off-message and don't convert
- Partners and analysts misrepresent your positioning
- Customers miss key releases and onboarding guidance
- You spend hours auditing and fixing content

The founder
Built by someone who lived this problem.

I spent 4 years in Product Marketing for fast-moving developer-focused startups like Builder.io and Netlify. My job was making sure everything we shipped was on-message.
The hardest part? Getting the entire team to actually use our carefully crafted messaging. I'd spend weeks building persona docs, only to watch them collect dust while content went out that missed the mark.
“I needed a tool that could help the entire GTM team adopt messaging without me having to review every piece of content.”
So I built PersonaBox—the tool I wish I'd had. It turns your messaging docs into a real-time writing assistant that actually gets used.
