What It Is

Self-serve message testing, built for teams that move fast.

The Persuasion Sandbox gives you direct access to Grow Progress's testing infrastructure without full-service setup. Enter your messages, select your audience, and launch. Designed for teams that need directional answers quickly, before committing to a full RMT study.

How It Works

Three steps from idea
to insight.

01

Write your messages

Enter 2–4 message variants directly in the Sandbox interface. Add a success question, vote intent, favorability, issue salience.

02

Choose your audience

Select from pre-built audience profiles: general public, likely voters, progressives, independents, or custom. Set your sample size.

03

Launch & read

Results arrive in your dashboard within 24 hours. Lift scores, statistical significance, and a topline summary, ready to act on.

Compare

Sandbox or Full-Service RMT ,
