Search filters
You can use one filter or combine several to narrow your results. Available filters include:
Company name | Find a specific company by name |
Companies similar to | Find lookalike companies — paid plans only |
Headquarters location | City, state, country, continent, or region |
Industry | Filter by industry sector |
Company size | Based on number of employees |
Company type | Public, nonprofit, educational, and more |
Year founded | Exact year or range — paid plans only |
Keywords | Terms describing products, services, or offerings |
Technologies | Companies using specific tech — paid plans only |
Funding | By round, amount, or date — paid plans only |
Saved companies | Hide companies you've already saved |
💡 Most filters offer an Include and Exclude option. For Keywords and Industry, you can also choose whether results must match All or Any of your selected values.
Finding companies
You can search using the AI Assistant or apply filters manually — or combine both.
Using the AI Assistant ✨
The AI Assistant turns a plain-language description of your target audience into the right search filters automatically. Just type what you're looking for and click the orange button, no need to set filters manually.
For example:
"Accounting companies in Germany"
"Fintech startups in the UK"
"SaaS companies with 50–200 employees in Europe"
You can also pick one of the suggested examples below the text field to get started. After your results appear, you can still adjust or add filters manually.
💡 The AI Assistant is limited to 10 searches/month on the free plan and 150 searches/month on paid plans.
After results appear, the AI may suggest ways to refine your search — for example, narrowing if there are too many results, or broadening if there are too few. Click Apply to use a suggestion, or type your own refinement directly.
Using manual filters
You can also build your search by selecting filters from the sidebar. Each filter includes Include and Exclude options, so you can zero in on exactly the right segment. Combine as many filters as you need.
Find similar companies
If you already have a company that's a great fit, use the Companies similar to filter to find lookalikes. Enter the company name and Hunter returns a list of businesses with a similar profile — no need to build filters from scratch.
💡 Companies similar to, Year founded, and Technologies are available on all paid plans.
Save and reuse searches
Once your filters are set, you can save the search to reuse it later.
Save a search
Configure your filters
Click Save this search at the bottom of the filters panel

Exploring company profiles
Click any company in your results to expand its profile. You'll see:
Company description
Industry and size
Headquarters location
Detected technologies
Inside each company profile, you can also find email addresses for that specific company in the Email Addresses tab, apply filters, and check recent company updates in the Signals tab.
Finding email addresses
Find emails for individual companies
Inside each company profile, you'll find associated professional email addresses. Click Reveal to access an email.
👉 Revealed contacts are automatically saved to your Leads section.
Use the People, Decision Makers, and Generic tabs to filter by contact type. You can also refine further using the following filters.
Job title | Filter by specific job titles |
Department | Filter by specific departments |
Verification status | Valid, Accept-all, or Unknown |
Location | City, state, region, country, continent, economic area, or nation |
Show only results with | Phone numbers, full names, or positions |
People per company | All, decision makers only, or a specific number |
Saved leads | Hide contacts already in your leads |

ℹ️ Bulk search limits (when no companies are selected):

Paid plans: up to 25,000 companies
Following companies
Each company profile has a Signals tab showing real-time updates — like new job openings and newly found email addresses. This is useful for timing your outreach to the right moment.
Click Follow this company to start tracking it as a Company Signal.
💡 Creating Signals is completely free.
Saving companies
You can save companies to your company leads and find emails for them later.
To avoid seeing companies you’ve already saved, use the dedicated Saved companies filter in Discover to hide companies that are already in your leads.
Save a single company
Open a company profile by clicking on it, then click Save company to add it to a new or existing list in your Leads Companies section. You can then find emails for it later.
Save companies in bulk
To save multiple companies at once:
Select specific companies, or skip selection to save all results
Click Save all companies (or Save selected if you've made a selection)
Choose an existing list or create a new one
💡 Limits:
Free plan: up to 100 companies at a time
Paid plans: no limit
Saved companies will appear in Leads > Companies, where you can manage and segment them.
Tips for better results
Combine filters — pairing Keywords with Technologies or Industry with Company size gives tighter, more relevant lists than using a single filter alone.
Play with filters — it's free and helps you identify the right leads
Use "Companies similar to" as a shortcut — if you already have one great-fit customer, this filter often outperforms building a manual filter set from scratch.
Exclude what you've already saved — turn on the Saved companies filter to avoid re-prospecting contacts you've already worked.
Follow before you reveal — if timing matters for your outreach, follow a company first and let Signals notify you when something changes (a new hire, a new email found) before spending credits.
Check back periodically — Hunter's company data is regularly updated, so a search with few results today may return more matches in the future.
