Builds a driver-based growth model - acquisition, activation, retention, monetization, and a loop factor - that projects users and revenue bottom-up, runs base/upside/downside scenarios, and names the one constraint to work on next. Use when someone asks "build me a growth model", "what should our user projection be", "which lever moves growth most", "model our viral loop", or wants projections driven by real inputs instead of a hockey-stick guess. Do NOT use for the SaaS MRR bridge, NRR, and…
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 Model A growth model is not a revenue forecast with a hopeful curve. It is a driver-based system that shows how inputs (traffic, conversion, retention) compound into output (users, revenue) - and where the leverage is. The costly mistake this prevents: drawing the output curve first and back-filling assumptions to justify it, which produces a plan nobody can steer because no team owns an input. ## Operating procedure Order matters: the loop must be identified before the equation is written, and the equation before any projection - otherwise the model quietly becomes a fixed-percent guess with extra columns. ### Step 1: gather inputs - Current active users and the definition of "active" (a meaningful action, not a login). - New users per period by channel, with each channel's volume and cost. - Activation rate: the share of new users reaching first value. From real funnel data where it exists. - Retention: the share of actives who stay each period - from cohort curves, never a flat assumption. If only aggregate churn exists, label the retention figure a guess. - Revenue per retained user, including expansion. …

How to install
mdr add skillmedev/skills/growth-model@sha256:9421cc43821e56fdThe line at the top of this page pins the label git:20261005.bea4ea5, 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.
