Define a real ICP and the developer personas in the sale. Use when the user says the product is "for developers," can't name who would say no, or is marketing to whoever holds the budget instead of who actually adopts.
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
# Who is this for? > "Developers" is not a market. It's a medium. If your ICP doesn't exclude anyone, it isn't one. **Use this when:** you describe your user as "developers" or "engineering teams," you can't name a person who is clearly *not* a fit, or you're aiming your messaging at the VP of Engineering because they have the budget. ## The core idea A usable ICP is specific enough that some people are obviously **out**. "Every developer" gives you nothing to say, because a message that speaks to everyone speaks to no one. Sharpen until exclusion is possible. And in almost every AI/dev-tool sale there is **more than one person**: the developer who adopts is rarely the person who pays. Market to the adopter; sell to the buyer. Confuse the two and you get great meetings and no decisions. ## Framework 1: The personas in the sale (Frankl) Map who plays each role. You need all of them for a complex sale; skip one and the deal stalls. | Persona | Cares about | Role in the sale | |---|---|---| | **Alpha Dev** | "What's possible?" Lives in the future. *No budget.* | Finds you, experiments, advocates internally, creates social proof | …

How to install
mdr add aidevgtm/gtm-cofounder/who-is-this-for@sha256:f5978232a2763bf4The line at the top of this page pins the label git:20260929.dfba153, 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.
