Ask five people on a sales team to describe the ideal customer and you will often get five answers. That is not a failure of the people. It is a sign the ICP was never written in a form anyone can use.
A useful ICP does three jobs
- It says who to contact. Not just an industry and a size, but the situation that makes a company likely to need you.
- It says who to leave out. Disqualifiers are half of an ICP, and the half most often missing.
- It says why now. The event, deadline or change that turns a good-fit company into a live opportunity.
Where ICPs go wrong
- Too broad. "Mid-sized B2B companies" describes most of the economy.
- Built on firmographics only. Size and industry say who could buy. Situations say who is likely to.
- Based on your biggest customers, not your best. Best means the ones who succeed, stay and refer.
- Never used. If it does not change who gets contacted, it is decoration.
A short method
- Look at your three best and three worst customers. What do the best share? What do the worst share?
- Write the sentence: we help [type of company] when [situation] because [problem].
- List five disqualifiers. Be honest about the customers that cost you more than they paid.
- Name the buyer roles, and what each cares about.
- List the events that usually come before a purchase.
- Put it on one page, and have the whole team sign it off.
If it does not change who gets contacted, it is decoration.
