More companies like your best customers
Match on what they sell, who they sell to and their size, then rank the rest of the market. A step-by-step playbook: what the signal means, whom to write to, what to say and how to measure it.
How do you find more companies like your best customers?
Start from three to ten of your best customers and look for companies that sell something similar, to a similar buyer, at a similar size. Match on what each company's own website says, not on an industry code. Drop the companies already in your CRM, find the person you usually sell to at each, and share what the customer they resemble achieved.
Why does the lookalikes play work?
Your best customers are the most precise description of your market you have. Industry codes and keyword lists are rough copies of the same idea.
Customers beat categories
Two companies with the same industry code can sell completely different things. Two companies whose websites read alike usually have the same problems.
It starts from what already works
You are not guessing at a market. You are asking for more of the accounts that already bought and stayed.
A proof point comes built in
Every lookalike resembles a customer. That customer's result is the reason to listen.
It improves with feedback
Marking a few results as good or bad sharpens the match for the rest of the list.
What counts as a good lookalike?
This play has no timing signal: fit is the reason to write. A good match has all of these:
- Sells a similar product or service, read from its own website.
- Sells to a similar buyer: the same kind of customer as your seed accounts.
- Falls in the same size range as the customers you picked.
- Is not already in your CRM as a customer or an open deal.
What looks like the signal but is not
- Seeds that are not alike
- Mixing very different customers gives a blurry average. Run one search per customer type.
- Famous seeds
- Seeding with your best-known logo instead of your best customer finds companies like the logo, not like the deal.
- Matching on size alone
- Size is a filter, not a match. Two 100-person companies can have nothing in common.
- Ignoring why they bought
- If your best customers share a trigger, such as a new team or a tool change, add it as a signal. Fit alone finds companies that may not need you yet.
How to run it, step by step
Six steps in the same five-part frame as every play. Each step says what you are after, why it matters and how to do it with any tools; the Breaknorm boxes show the shortcut.
- 01Signal
Pick your best customers
Goal. Three to ten customers that describe the pattern you want more of.
Why. The seeds decide everything that follows. Pick the customers you would clone: they bought quickly, stayed, and would recommend you.
How.- Choose customers by fit and outcome, not by logo.
- Keep them similar to each other; run a separate search for each customer type.
- Three is enough to start; ten gives a sharper match.
Start from your customers
find_similarfind_similar({ "domains": ["shipvane.io", "portlane.io"] })You end withA short list of seed customers, one search per type.
- 02Signal
Match on offer, buyer and size
Goal. A ranked list of companies like your seeds, without your existing customers.
Why. Matching on what companies say about themselves finds the ones with the same problems. Excluding your CRM stops you writing to customers and open deals.
How.- Read the top results yourself before trusting the list.
- Mark a few as good or bad fits; the ranking follows.
- Exclude current customers and open deals with a list.
The filters behind it
find_similar + create_list{ "similar_to": ["shipvane.io", "portlane.io"], "exclude_list": "crm-customers", "employees": { "min": 20, "max": 500 }, "limit": 500 }You end withA ranked list of lookalikes, each tagged with the customer it resembles most.
- 03Who
Find the buyer you usually sell to
Goal. The same role at each lookalike that bought at your seed customers.
Why. If your customers were bought by Heads of Operations, the lookalikes will be too. Copy the buyer, not just the company.
How.- Check who signed at your seed customers: function and level.
- Find that role at each lookalike.
- Titles vary; match on function and level, not exact wording.
Find the buyer
search_people{ "function": "operations", "level": ["head", "director"], "company": "parcelyn.com" }You end withOne named buyer per lookalike.
- 04Find
Get an email that is verified
Goal. A working address for each buyer.
Why. Lookalike lists can be long. Verifying before you send keeps your bounce rate, and your domain, clean.
How.- Find the address from the name and the company domain.
- Verify it at the mail server.
- Hold contacts whose address cannot be confirmed.
Find and verify with Breaknorm
find_email · verify_emailfind_email({ "name": "Katrin Vogel", "domain": "parcelyn.com" })You end withA verified email per buyer.
- 05Say
Share what a company like theirs did
Goal. A message that shows the similarity and offers a peer's result to read.
Why. A result from a company like theirs is more convincing than any claim. Offered as something to read, it asks for very little.
How.- Say what they have in common with your customer, in one line.
- Name the problem that customer had, which they probably share.
- Offer the write-up of what changed and ask if you can send it.
You end withOne message per company, built on the customer it resembles.
- 06Measure
Compare lookalikes with your usual lists
Goal. A view of which seeds produce accounts that reply and buy.
Why. Some customers make great seeds and some don't. Tracking by seed tells you which pattern to grow.
How.- Tag each account with the seed customer it resembles.
- Compare reply and meeting rates against your usual outbound.
- Re-run when you win new customers; the pattern shifts.
You end withA ranking of seed customers by the pipeline their lookalikes create.
A worked example, start to finish
One company, through every step. The companies and the person are invented; the steps are the real ones.
- Signal
Your best customers are Shipvane and Portlane: software for online retailers, 50 to 200 people, bought by operations.
- Signal
Parcelyn, a post-purchase tracking company in Munich with about 120 people, comes back as a 92% match to Shipvane. It is not in your CRM.
- Who
At Shipvane, the Head of Operations signed. At Parcelyn, that is Katrin Vogel.
- Find
[email protected] comes back valid from the mail server.
- Say
The message names what Parcelyn and Shipvane have in common and offers the Shipvane write-up.
- Measure
Tagged with Shipvane as the seed, so you can see which customer makes the best lookalikes.

What to write to a lookalike company
A short email that gives before it asks: something useful for the situation they are in, not a meeting request. Why each line is there:
Hi Katrin, Parcelyn and Shipvane work with the same kind of customer: online retailers who have to tell shoppers where their parcel is.
As Shipvane's retailers grew, questions about delivery status grew faster than their support teams did.
We wrote up what Shipvane changed and what it did to their ticket volume, in two pages.

When not to run this play
- You name a customer without their permission.
- Your seed customers are very different from each other.
- You have fewer than three customers; start with a market map instead.
- The lookalike is already in a deal with you.
- You use fit as the only filter on a big list; add a signal to know when to write.
How to measure whether it works
Track a few numbers per batch and compare them over time. What counts as good depends on your market, so the trend matters more than any benchmark.
- Reply rate compared with your usual lists
- Lookalikes should do better than a broad list. If they don't, look at the seeds.
- Results by seed customer
- Which customers produce lookalikes that reply and buy.
- Share of results you mark as good
- If it is low, the seeds are too broad or too different from each other.
- Meetings per 100 companies
- The number that tells you whether the play is worth repeating.

Questions about this play
How many customers do I need to find lookalikes?
Three is enough to start, and ten gives a sharper match. They should be similar to each other; if your customers fall into different types, run one search per type.
What makes a good seed customer?
One you would clone: they bought quickly, stayed, and would recommend you. Your best-known logo is not always your best seed.
How is this different from filtering by industry?
Industry codes put very different companies in the same box. Lookalikes match on what companies actually sell and to whom, read from their own websites.
Should I name the similar customer in my email?
Only with their permission. Without it, describe them instead: "a parcel tracking company about your size".
Can I run this play without Breaknorm?
Yes, for a short list: search for your customers' competitors and read their websites. Matching thousands of companies on what they sell and ranking them by fit is the part a data API does for you.
Video transcript: The lookalikes play in two minutes
Your best customers are the most precise description of your market you have. Industry codes and keyword lists are rough copies of the same idea.
Pick three to ten of them, and look for companies that sell something similar, to a similar buyer, at a similar size, read from each company's own website.
Mark a few results as good or bad, drop the companies already in your CRM, and find the person you usually sell to at each.
Then share what the similar customer achieved, as something to read, and ask if you can send it.
