It depends on where you are

Every answer here was said to one founder. Find the one closest to you, then read what that founder was told.

You sell a service and take any client

Look at the clients you served best and liked most, then aim for more like them.

Farzad Khosravi,Josh Boone

Your customer description is too broad

Describe the buyer in detail: who runs the business, its size and its revenue.

Sean Weisbrot,Nina Jung,Nadia Bukina

You have no paying customers yet

Wanting is not paying. Ask people about the problem, what they do today and whether they would pay, or solve it well for one customer you trust.

Peter van Jaarsveld,Hans Bunes,Sonya Jamula,Tina Louise

You cannot choose between customer groups

Pick the group most in pain and most likely to spend, and use the data you have.

Describe the buyer

Get specific about the person and the company

Said to a founder selling a service to traditional small businesses

Maybe tighten it to who runs the business

You can see who the owner is on a registry of companies. I'm pretty sure you can find how old they are. Maybe you don't want to work with people who are 60, 70 years old, because they're close to retirement. They have worked like this their whole life. They probably don't care. But maybe the right people are younger. They have, for example, taken over, or they're coming into the business.

Said to a marketing consultant whose ideal customer description was broad

Get really granular on who that avatar is

You should have one customer avatar. If you have the right avatar, you can spend all of your time solving one avatar's problem rather than five or ten avatars' problems.

Said to a founder selling lead generation, wary of picking one industry

You want to be in the middle

You don't have to be picking the industry. It can be location, for example: companies based in one city, or a broad region. Or it could be businesses generating seven figures, one to 10 million in revenue.

Know who the buyer is, not just the company

When we were going after medical practices, we learned the admins are the ones paying attention and trying to make their lives easier. The doctor does not have a clue what's happening, but is the one who's going to dole out the money.

Said to a founder starting a consultancy with no proven customers yet

Test your hypothesis with people you know

I knew a consultant who struggled. I think he ended up narrowing down to one very, very niche specific vertical: maritime technology providers. All of a sudden his book of business flourished because he did two things. He was very specific about what he'd look at, and he specialized in this industry.

Start from clients

Look at the people you already serve

Said to a founder just out of beta with no paying clients

Solve the problem really well for one person

Every go-to-market person will disagree with me. I don't love ICPs. I think they force us to over-generalize an ideal customer. If you try and please everyone, you please no one.

Said to a consultant doing a different service for each client

You have to niche down

How you niche down depends on a couple of things. Of all the clients you have, which ones are the most valuable to you? Valuable meaning they love your service, they're going to keep using you, and you think you're really good at providing that service.

Said to a founder whose competitors target the same customers

We can't be everything to everyone, pick a lane

If you don't really see a unique lane, you could maybe put some money towards paid advertising just for a couple of weeks. Try different ads through different segments and see what traction you get. But I wouldn't overthink it either. If you can see something now from your analysis and data, just go with that.

Said to a founder with inconsistent leads and projects they don't like

Get very specific on who you can help

I think it's just: who do you want to work with? That influences everything. In my opinion, everyone gets it wrong: they focus on "we do this service", and it's like, well, you're interchangeable.

Start from pain

What hurts today, and whether they will pay to fix it

Said to a founder with a digital product for busy parents

The most important things are the pain points

If they go on a search engine, what would they type? You might be a nutritionist selling healthy meal kits, and your customers are searching for "how do I make my child eat vegetables?" They're not searching for a meal kit.

Said to a founder unsure which customer group to prioritise

Best guesstimate: most in pain, more likely to spend

You might get it wrong and waste a bit of time, but typically you've built the process and infrastructure you need for the next ICP.
