Apollo.io has become one of the most powerful sales intelligence platforms on the market — and if you're not using its company search feature to its full potential, you're leaving serious money on the table.
Whether you're a sales rep hunting for new accounts, a marketer building a targeted campaign, or a founder doing competitive research, Apollo's company search gives you access to a database of over 275 million contacts and 73 million companies. The key is knowing how to use it properly.
What Is Company Search in Apollo.io?
Company search in Apollo.io allows you to filter and identify companies based on specific attributes like industry, size, revenue, location, technology stack, and more. Instead of cold-guessing your ideal customer profile, you use real data to pinpoint the exact companies that match your target market.
This is prospecting on steroids — and once you learn how to do it right, your outbound strategy will never be the same.
Step-by-Step: How to Search Companies in Apollo.io
Here's exactly how to search companies in Apollo.io from start to finish:
- Log in to your Apollo.io account and navigate to the left-hand sidebar
- Click on "Search" and then select "Companies" from the dropdown
- You'll land on the Companies search page, which shows a massive filterable database of businesses
From here, the real magic begins.
Using Filters to Narrow Down Your Search
Apollo.io's filtering system is where company search becomes genuinely powerful. You're not just searching by name — you're building a precise profile of your ideal company.
Here are the most important filters you should be using:
- Industry — Filter by specific verticals like SaaS, healthcare, fintech, e-commerce, or manufacturing
- Employee Count — Target companies by size, from solo founders to enterprise organizations with 10,000+ employees
- Annual Revenue — Narrow down companies based on their estimated revenue range
- Location — Search by country, state, city, or even postal code
- Technologies Used — Find companies using specific tools like Salesforce, HubSpot, Shopify, or Zoom
- Funding Stage — Target startups that just raised a Series A or B if timing matters for your pitch
- Keywords — Search company descriptions and bios for specific terms relevant to your niche
Each of these filters stacks on top of each other, so the more you layer them, the more targeted your list becomes.
How to Use the Keyword Search Bar
At the top of the Companies page, you'll find a search bar where you can type a company name directly. This is useful when:
- You're researching a specific competitor or prospect
- You want to verify a company exists in the Apollo database
- You need to quickly pull up a company's profile before a sales call
Just type the name and Apollo will surface the closest matches, including LinkedIn URLs, headcount data, and contact information.
Saving and Building Company Lists
Once you've applied your filters and found a solid set of companies, don't let that hard work disappear. Apollo lets you save your search as a list so you can come back to it later or push it into a sequence.
Here's how to save your company search:
- Click the checkbox next to the companies you want to save (or select all)
- Click "Save to List" in the action bar that appears
- Name your list something descriptive like "Series B SaaS Companies — US — 50–200 Employees"
- Access your saved lists anytime from the "Lists" section in the sidebar
This is incredibly useful for organizing your pipeline by segment, region, or campaign.
