I start every engagement with the same two questions: which companies do you sell to, and to whom inside them. Most sales and marketing teams blur the two or work with only one. This is not a theoretical mistake. It is why most international market entries slow down in the first six months.
ICP: the company
The ideal customer profile is company-level: size, industry, country, technological maturity, existing partners. It filters the input side of the pipeline. For software sold to e-bike distributors, the ICP is not "distributors" but "distributors with 50 to 500 dealers in DACH and Benelux who do not yet have a dealer portal". That sentence already tells you whom not to call.
Buyer persona: the person
Inside the ICP someone decides, someone uses, and someone blocks. The persona is about their pain points, their objections and how they judge success. The managing director asks about margin, the operations lead about rollout time, IT about security. Same product, three messages.
Why you need both
- Without an ICP the persona floats in a vacuum: the right message to the wrong companies.
- Without a persona the ICP is an empty frame: the right companies, who do not see why it is for them.
- A good market entry plan layers the two, country by country. The German and the Dutch persona are not the same, even when the company profile is identical.
This is the first week's work in every market discovery audit I do. Not because it is fashionable, but because everything after it goes faster.
