Using the Audience Builder for the first time, or need a bit of a refresher? The Audiences section of Getting Started gives step-by-step instructions on how to create an audience.


Audience Builder allows you to add filters at both a company and contact level, to help you determine your target audience, or a segment of people that would be most interested in your Organization and what you are offering. The filters in Outbase are:

Company Filters:

1. Companies 2. Keywords 3. Company size 4. Industries 5. Location 6. Annual revenue 7. Technologies used

Contact Filters:

8. Job titles 9. Locations 10. Names

Below we'll look at these filters in more detail to make sure you use them in the best way for your campaign(s).

Company Filters

These filters apply to the types of companies you want to target.


Use this filter if you want to target specific companies. You can also use this to exclude companies from your audience (see Exclude below). Example: Outbase

You can also use exclude companies. See Exclude, below, for more information.

Outbase allows you to upload individuals and domains you don't want to contact through your campaigns by uploading exclusion lists. See the Exclusions section of the User Guide for more information.


This filter looks for the keywords you input in the company descriptions in our database. It can be useful when trying to narrow down to a specific type of company that could be classed in a number of different industries. Example: Fintech

Company size

This filter allows you to choose what size of companies you want to contact. For example, if you are targeting start-ups these would be the smaller companies, or enterprises would be the bigger ones. Company size is, depending on the industries, also a good indicator of company revenue, and although you are able to search based on annual revenue (see below), this can exclude companies and contacts where this data isn't available. Example: 10,000+ employees


Choose the specific industries based on where your offering is most applicable, where your client base mainly sits, or from industries you are looking to tap into, but don't have a network for yet. Example: Banking

With over 140 different industries to choose from, we've created a quick overview to help you with your selections in Industries, on our next page of the User Guide.


This filter uses the company location, so if you wanted to target only companies based in the United States, you would select this using the region option. You can also filter this as a radius from a ZIP/postcode. Note, this filter is only for the company's main location, e.g. using the United States, will bring up companies with their main location in the US, but they may have offices outside of the US. Similarly, this will exclude companies with their main location outside of the United States, even if they have an office or a large presence in the US. Region example: United States ZIP/Postcode example: 10001, New York, NY, USA within 100 mi (160 km) radius

Annual revenue

Searches for companies with an annual revenue within the given ranges. Please note as above, using this filter will exclude companies where the annual revenue is unknown. For these companies, company size can instead be used as an indicator of revenue. Example: 1m-10m

Technologies used

Where known, our database will provide you with information about technologies used by companies. This can be used, for example, to find out which companies are using e-commerce platforms. Example: Shopify

Contact Filters

These filters apply to the contacts you want to target.

Job Titles & Seniority

Select the job titles that will be most receptive to your organization and offering, using our comprehensive search function. In the Job Title section, you can select departments where it is most likely for you to find the ideal buyers for your product or service. Simply click on the drop-down menu under Departments and start making your selections. There’s also additional segmentation by functions within each department. For instance, if you're looking for job titles within the Marketing department, you can now precisely choose the specific functions using the "+" icon located on the right side of the department.

Once you've selected your target departments and functions using the Job Title filter, you can further refine your search by specifying the desired seniority level. Whether you need senior management roles like Heads, Directors, Managers, or non-management positions, our platform has you covered. Simply apply the filters and get results tailored to your preferences. You can also use this to exclude job titles from your audience (see Exclude below). Example: Founder

You can also use exclude job titles. See Exclude, below, for more information.

You can also use a boolean search in the job title filter. See Boolean Search, below, for more information.


This filter uses the contact's location, to search for contacts in a certain region or radius from a ZIP/postcode. Region example: United States ZIP/Postcode example: 10001, New York, NY, USA within 5 mi (8 km) radius

Company and contact location work independently, see the below examples: COMPANY LOCATION: United States CONTACT LOCATION: United States Will look for companies with their main location in the US and contacts located in the US. COMPANY LOCATION: None CONTACT LOCATION: United States Will look for contacts located in the US, from companies with their main location worldwide. COMPANY LOCATION: United States CONTACT LOCATION: None Will look for contacts located worldwide, from companies with their main location in the US.


Filter your contacts by first or last names. Example: John


With the company and job title filters, you can choose certain companies and job titles to exclude.

To exclude, first add the company or job title to the filter, then click the exclude icon (🚫 ) on the left. The company or job title will now move to excluded:

Example: In the above screenshot Apple is included as a company, but Microsoft is excluded. Marketing job titles are included, but job titles with assistant will be excluded from the audience.

To add any exclusions back into your filter, click the check icon (βœ…) to the left of the exclusion.

A boolean search uses a combination of keywords and the three main Boolean operators (AND, OR, and NOT) to find more accurate and relevant results for your audience(s).

A brief introduction is given below:

Quoted searches: This will search for an exact phrase. For example:

Product Manager

without quotation marks will bring up any title with Product and Manager e.g. Product Development Manager or Product Risk Manager. But using quotation marks:

"Product Manager"

will only bring up titles with these words together. So both these searches will bring up Product Manager titles, but using a quoted search will exclude results where these two words aren't together.

Using a quoted search will still bring up titles with more than just "Product Manager" e.g. Senior Product Manager or Digital Product Manager, but would exclude where these two words are not next to each other e.g. Product Development Manager.

OR searches: OR searches are used to see results that include one or more terms. For example, using:

Sales OR Marketing

would bring up results with any of these terms in, such as Chief Sales Officer or Director of Marketing, as well as titles that might include both terms, such as Head of Sales & Marketing

AND searches: AND searches are used to see results that include all the terms you include. For example, using:

Sales AND Marketing

unlike in the example above, would not bring up Chief Sales Officer or Director of Marketing, as it would only show titles that include both of these terms. Job titles that would be shown are Head of Sales & Marketing, Head of Sales and Marketing, Head of Marketing & Sales, Head of Marketing and Sales, as well as others with more terms, such as Director of Sales, Strategy and Marketing.

NOT searches: NOT searches are used to exclude a term or terms from your results. For example:

Marketing NOT Assistant

would search for job titles that include the term Marketing, but that don't include Assistant. The following job titles would appear: Director of Marketing, Chief Marketing Officer, Marketing Manager, but these would be excluded: Marketing Assistant, Assistant Marketing Associate.

Parenthetical searches: Parentheses are used to create more complex searches. For example, to find contacts working in Product, but who don't have Digital or Online in their job title, use:

Product NOT (Digital OR Online)

With this, you would get results like Head of Product, Chief Product Officer, Product Manager, but the following would be excluded: Head of Digital Product, Chief Product Officer - Online & Digital, Online Product Manager.

NOT, AND, or OR operators, must be used in uppercase characters.

Wildcard searches * are not supported.
