Build a growth experimentation system — ICE scoring, growth sprints, experiment design, statistical significance, and learning repositories. Use when building an experimentation program, running growth sprints, prioritizing tests, or establishing a data-driven growth culture. Triggers on: "experimentation", "growth experiments", "A/B testing program", "ICE scoring", "growth sprint", "experiment design", "test velocity", or any growth experimentation request.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Growth Experimentation ## Overview The companies with the highest growth rates don't have better ideas — they have better systems for testing ideas. A high-velocity experimentation system runs 15-30 experiments per month across acquisition, activation, retention, and monetization. Most experiments fail. That's by design. The team that learns fastest from each failure wins. ## When to Use - "Build an experimentation program" - "Set up growth sprints" - "Prioritize experiments with ICE" - "Increase our test velocity" - "Create a learning repository" ## Authoritative Foundations - **Sean Ellis & Morgan Brown (Hacking Growth)** — coined "growth hacking." North Star Metric. Growth experimentation loop: analyze → ideate → prioritize → test → learn. - **Brian Balfour (Reforge, ex-HubSpot VP Growth)** — increasing HubSpot's experiment velocity from 5 to 20/week produced 3x growth rate improvement. Four Fits Framework: Market-Product, Product-Channel, Channel-Model, Model-Market. - **Andrew Chen (a16z, ex-Uber Growth)** — The Cold Start Problem. Growth teams at scale. - **Fareed Mosavat (Reforge, ex-Slack Growth)** — experimentation systems. ## Step-by-Step Process …

How to install
mdr add leadmagic/gtm-skills/growth-experimentation@sha256:f138e24a43d3d534The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
