What It Is

The world's largest database of
what actually persuades people.

The Persuasion Library aggregates findings from select Rapid Message Tests run on the Grow Progress platform — a growing repository of findings across issues, audiences, and message types. Search by issue area, audience segment, message frame, or outcome.

See what's already worked for campaigns and organizations like yours, and what hasn't.

Use Cases

How teams put the
Library to work.

Whether you're launching a campaign, briefing a creative team, or reporting to funders, the Library has a role.

01
Campaign kickoff
Before you write a single message, search what's already been proven to work with your audience on your issue. Start with evidence, not intuition.
02
Creative brief
Give your creative team evidence-backed messages to build from, not just intuition. Fewer rounds of revisions. Stronger work from day one.
03
Funder reporting
Show funders you're building on a proven body of research, not starting blind. The Library is proof your strategy is grounded in data.
