Growth & GTM
tools.

Free interactive tools for growth and GTM teams: a UTM campaign-URL builder, a lead-scoring grid, and a cohort retention curve. No signup, runs in your browser.

These are the interactive growth tools that don't fit the calculator mold. A calculator runs a formula and shows you a benchmark; a tool does a job. Build a tagged campaign URL, score a list of leads against a fit-and-intent grid, or plot a retention curve from raw cohort counts. Each one is free, runs entirely in the browser, and saves nothing, so you can paste in real numbers without a signup or a privacy worry.

Every tool here came out of work that kept getting redone by hand. The UTM builder enforces the naming conventions that keep analytics clean. The lead-scoring grid turns a vague 'this account feels good' into a tiered, defensible number. The cohort curve makes a flat retention line obvious before it shows up in the board deck. Browse the set below, and reach for the calculators when you need a formula and a benchmark instead.
