why we built this
We shipped launches without a PMM
Three PMs, one designer, one PMM. We shipped enough launches to know the hard part isn't the product - it's the four docs around it that get rewritten every quarter. One paste, four docs, one weekend. That's Supabrief.
What we believe
Drafts aren't the job. Ships are.
Drafts aren't the job. Ships are.
Tier and persona do what a prompt can't.
Dashboards don't write launches. PMs do.
Every feature earns its place - or gets cut.
