Ideal customer profile (ICP).

The single document that makes every other marketing decision easier. Here is what an ideal customer profile is, how it differs from a persona and how to write one that bites.

Definition
An ideal customer profile (ICP) describes the kind of company that gets the most value from your product and is the most profitable for you to serve, so you can aim everything at it.

An ICP is about the company, not the person. That is the difference from a persona. Get it sharp and your ads, content and sales all aim at the same target. Leave it fuzzy and every channel quietly aims somewhere slightly different.

Benchmarks

Ideal customer profile versus buyer persona.

An ideal customer profile describes the company you want to win. A buyer persona describes the individual humans inside that company you have to convince. You need both but the ICP comes first, because it bounds who the personas even belong to.

The common mistake is jumping to personas without an ICP, which produces lovely character sketches of people at companies you should never sell to. Define the company first, then the people inside it.

How to improve it

How to write an ICP that bites.

01

Mine your best customers

Build the ICP from the accounts that retain and expand, not the ones that simply bought.

02

Name the exclusions

A real ICP says who you are not for. The exclusions are where the sharpness comes from.

03

Make it firmographic first

Start with the company, industry, size, region, before you sketch the humans inside.

04

Use it everywhere

An ICP that lives in a doc is useless. It should bound your targeting, content and qualification.
