Better questions. Deeper testing.
We break things apart to understand what’s working, what isn’t, and what needs another look.
Members test different scenarios, challenge assumptions, and share the details behind their findings. Results that didn’t go as expected are just as useful as the wins.
Much of what we learn comes from the work other members generously share. Everyone brings a different perspective, and that makes the group valuable.
Bring your experiments. Bring your curiosity.
We’re selective about who joins and remains in the group. Its value comes from members contributing useful, first-hand knowledge and trusting one another with it.
Members must meet four core requirements:
Actively test across multiple categories
Run ongoing experiments across different categories, scenarios, and approaches. Your testing should extend beyond publishing listicles.
Bring real case studies
Share examples of your work, the results, and what you learned. Be willing to explain how you approached the testing.
Share openly and regularly
Contribute methods, findings, and unanswered questions. Take an interest in other members’ experiments and join the discussions.
Keep things confidential
What’s shared within the group must stay within the group. Respecting that privacy gives everyone the confidence to share openly.
You don’t need every answer. You do need an ongoing commitment to testing, sharing, and learning.
An active group takes active participation.
We regularly review participation and remove members who no longer meet these commitments.
The expectation is simple: keep experimenting, share what you’re learning, and respect the people sharing with you.
Working on something interesting?
Tell us what you’re testing, the categories you’re exploring, and the case studies you can share.
We review applications and will reach out if your work and participation fit the group.
