Ideal customer profile and buying signals: who to contact, and when

ICP vs buyer persona
| Ideal customer profile | Buyer persona | |
|---|---|---|
| Describes | A company | A person inside it |
| Answers | "Which companies should we sell to?" | "Who do we talk to, and what do they care about?" |
| Example | 10–50 person software companies in the US | Founder or head of growth who owns the pipeline |
You need both: the profile decides who goes on your list, the persona decides what you say.
A B2B example
Ideal customer profileExample
- Industry
- B2B software
- Size
- 10 to 50 employees
- Stage
- Seed to Series A
- Location
- US and UK
- Situation

- Trigger
- New funding round or a first sales hire
- Avoid
- Agencies and companies under 5 people
The trigger is the line that matters most. It tells you when to reach out, not just who to reach.
Write yours in ten minutes
- List your five best customers: the ones who pay on time and get value.
- Write down what they share: industry, size, location, team setup.
- Note what was happening when they bought. That's your trigger.
- Write down who to avoid, based on customers who churned or never fitted.
Buying signals to watch for
Company changes
- Raised a funding round
- Opened a new office or market
- Launched a new product
Hiring
- Hiring for the role you support
- A first hire in a new function
- A sudden hiring spike
People
- A new leader in the team you sell to
- A past champion joins a new company
Intent
- Visiting your pricing page
- Comparing alternatives
- Asking for recommendations in public
Mention the signal in one line, connect it to a problem, act within a few weeks, and only use information the person made public.
