For: Founders selling to everyone and closing too few of them
Who is my ideal customer?
My answer, as of Oct 5, 2026
Your ideal customer is defined by the problem, not demographics: a type of company with an urgent trigger, a person who owns the problem and can sign, a pain that costs them money, time or risk, and a place they already gather. If you can't turn it into a list of 100 names, it isn't specific enough.

Where the line actually sits
- 2 sentences
How long the profile should be
One for the company, one for the person.
- 100
Companies you should be able to list
If you can't find 100 that match, the profile may be too narrow or too vague to reach.
- 10,000
The sign it's too broad
If you find 10,000 in an hour, it's probably too broad to give you an edge.
- 6 months
How often to revisit it
Your best customer at $1M is rarely your best at $10M.
What changed in the last year
- Reaching everyone got cheap, so reaching everyone stopped working. The founders who win pick a narrow buyer and show up where that buyer already listens.
What most founders get wrong
“Our customer is mid-sized companies.”
Defining the ICP by demographics instead of by the problem makes it impossible to turn into a list of names.
“We want to sell to enterprises.”
Choosing the buyer you'd like instead of the one who's buying is the most expensive mistake on the list.
When I'd tell you the opposite
- Widen it once deals close faster, customers stay longer and they refer people who look just like them. Before that, widening hides the signal.

- Shorter sales cycles, a higher win rate, best customers who sound alike on calls, and cheaper marketing because you know where to show up.
