Similar companies
In short
Similar companies are businesses that share key traits with a reference company, such as industry, employee count, location, tech stack, and business model. In go-to-market work, the reference is usually a best customer, a closed-won deal, or a target account.
The idea is simple: if a company bought and succeeded, others that look like it are more likely to do the same. Similar-company search turns a handful of known wins into a longer list of prospects. It is the practical core of lookalike targeting, and "similar companies" is the phrase people use when searching tools for it.
What makes companies similar
- Firmographics: Industry, size, revenue band, region, and funding stage.
- Technographics: The software and infrastructure they run.
- Business model: B2B or B2C, self-serve or sales-led, product or services.
- Description and focus: What the company says it does, which matters when industry labels are too coarse.
How to find similar companies
Pick a good seed
Use customers that stayed, expanded, and fit your product well. A seed list full of poor-fit deals produces a poor-fit target list.
Choose the traits that matter
Decide which traits explain the win. A cybersecurity tool may care about compliance regime and stack, while a payroll product cares more about headcount and region.
Search, then review
Run the search with filters or a similarity tool, then check a sample by hand. Remove companies that match on paper but fail a disqualifier, such as being a competitor or too small.
Where teams use it
- Outbound prospecting: Build lists around a named customer, such as "companies like Acme".
- Paid campaigns: Seed audiences from existing accounts.
- Expansion: Find sister companies or peers of a customer for referrals.
- Market sizing: Count how many similar companies exist to test whether a segment is big enough.
Common mistakes
- One-customer seeds: A single logo can mislead. Use several wins to see the pattern.
- Matching on size alone: Two firms of the same headcount can have different needs.
- Skipping timing: Similar does not mean ready. Add buying signals before outreach.
Similar companies vs. lookalike companies
The two terms overlap heavily. Similar companies is the general search idea; lookalike companies usually implies a modelled match against a defined customer seed.
Similar companies FAQs
How do I find companies similar to my best customers?
List your best customers, identify the traits that explain their success, then search for companies sharing those traits using filters or a similarity tool. Review a sample manually and remove those that fail a disqualifier before outreach.
What makes two companies similar in B2B?
Similarity is usually judged on industry, company size, region, funding stage, tech stack, and business model. The most useful traits are the ones that explain why the reference customer bought and stayed.
Are similar companies and lookalike companies the same thing?
They overlap. Similar companies is the general idea of finding businesses that resemble a reference account. Lookalike companies usually means a modelled match built from a seed list of customers, often used for targeting and ads.
Can I find companies similar to a competitor?
Yes. Companies that resemble a competitor’s customers often have the same problem. Use the competitor’s public customer list as a seed, then check fit against your own ICP so you do not chase accounts you cannot serve.
