Background & Team
Our Origin Story
Experimentation Club started as a group of practitioners sharing ideas, challenges, and learnings about how to run better experiments. The newsletter grew from those conversations — designed to give teams practical insights they can apply immediately.
We continue to expand the Club as a space where experimentation professionals learn, connect, and stay informed.
