The Companies similar to filter in Hunter Discover helps you find companies that match a specific business you already know.
This is useful when you’ve identified an ideal customer (ICP match) and want to quickly discover similar companies without building complex filters.
How it works
Hunter suggests similar companies based on:
Industry
Company description
Keywords
This lets you expand your prospecting from one strong example instead of starting from scratch.
Within each similarity group:
Companies with available email addresses are ranked first
If there's no strong direct match, Hunter falls back to the target company's own industry to keep results relevantc
💡 Discover is available on all paid All-in-one outreach plans.

Common questions or issues
Why can’t I use this filter?
This feature is only available on paid plans. Check your subscription in Hunter plans.
Why are some results not exact matches?
Similarity is based on multiple signals — industry, keywords, and description — so results can vary in how closely they match. Companies without available email addresses are also ranked lower within their group, which can affect where a result appears in the list.
