How to Opt Out of Demandbase

Demandbase is one of the largest account-based marketing (ABM) and intent data platforms in the B2B space. It helps sales and marketing teams identify which companies are visiting their websites, what topics those companies are researching, and which individual contacts to target. If you have ever wondered how a vendor seemed to know your company was evaluating their product category before you ever filled out a form, Demandbase is likely part of the answer. Here is how to opt out and limit the data they collect about you.

What Is Demandbase and What Data Does It Collect?

Demandbase operates as a registered data broker in California (Registration #550546) and provides B2B marketers with tools to identify, target, and engage business accounts. Unlike traditional consumer data brokers that focus on individuals, Demandbase primarily works at the company level but still collects and processes personal information to power its platform.

The types of data Demandbase collects include:

• Business contact information: Names, work email addresses, job titles, phone numbers, and company affiliations
• IP-based company identification: Demandbase maps IP addresses to companies, allowing its customers to see which businesses are visiting their websites even without form fills
• Intent signals: Topics and keywords that your company appears to be researching across the web, aggregated from third-party content consumption data
• Website behavior: Pages visited, time on site, content downloaded, and engagement patterns on websites that use Demandbase tracking
• Cookie and device data: Tracking cookies, browser identifiers, and other device-level signals used to connect browsing activity to company profiles
• Firmographic data: Company size, industry, revenue, location, and technology stack information

Demandbase aggregates this data to build detailed profiles of business accounts and the individuals within them. This information is then provided to B2B marketers for targeted advertising, personalized website experiences, and prioritized sales outreach.

How to Opt Out of Demandbase: Step-by-Step

Demandbase is CCPA compliant and offers a formal opt-out process. Follow these steps to submit your request:

1. Visit the Demandbase privacy page:

   Navigate to demandbase.com/privacy/ in your browser. You can also scroll to the bottom of any page on demandbase.com and look for the "Do Not Sell My Info" link in the footer.

2. Locate the opt-out form:

   On the privacy page, find and click the "Do Not Sell My Personal Information" or "Do Not Sell My Info" link. This will take you to an online web form where you can submit your opt-out request.

3. Fill in your personal details:

   Complete the form with your name, email address, and any other required information. Use the work email address and details that Demandbase is most likely to have on file. If you have multiple work emails, you may need to submit separate requests for each.

4. Submit the form:

   Review your information for accuracy and submit. You should receive an on-screen confirmation that your request has been received.

5. Click the email confirmation link:

   Demandbase will send a verification email to the address you provided. You must click the confirmation link in this email for your opt-out to be processed. Check your spam or junk folder if the email does not arrive within a few minutes.

Alternative: Opt Out by Phone

If you prefer not to use the online form, you can opt out of Demandbase by calling their dedicated privacy line:

• Phone: 1-866-777-5530

When you call, be prepared to provide your full name, email address, and company name so they can locate your records. Ask for written confirmation that your opt-out request has been received and is being processed.

The Cookie Problem: Why You May Need to Opt Out Again

This is a common limitation with advertising and tracking platforms that rely on cookie-based opt-outs. To minimize the issue:

• Do not clear all cookies indiscriminately — use selective cookie management tools that preserve opt-out cookies
• Use a privacy-focused browser extension that blocks Demandbase tracking scripts before they load
• Consider a VPN or IP masking service to prevent IP-based company identification, which operates independently of cookies
• Re-submit your opt-out periodically, especially after major browser changes or device switches

What Opting Out Actually Does (and Does Not Do)

It is important to understand the scope and limits of a Demandbase opt-out:

What It Does

• Prevents Demandbase from selling your personal information going forward
• Suppresses your data from future API responses and targeting lists provided to their customers
• Removes your cookie-based tracking from Demandbase's network

What It Does Not Do

• Recall previously shared data: Any company that already received your data through Demandbase will retain it in their own CRM or marketing platform. You would need to contact those companies separately.
• Stop IP-based company identification entirely: If your company's IP range is mapped in Demandbase's system, other employees at your company can still trigger account-level identification. Your individual opt-out does not remove your company from their IP mapping database.
• Prevent re-collection from public sources: If your professional information is publicly available on LinkedIn, company websites, or industry directories, Demandbase may re-collect it over time.

Beyond Demandbase: Other B2B Intent Data Platforms

Demandbase is part of a broader ecosystem of B2B intent data and ABM platforms. If your data is in Demandbase, it is almost certainly in similar platforms as well. Other services you should consider opting out of include:

• 6sense: Another major ABM platform that uses intent data and AI to identify in-market accounts
• Bombora: The company that invented the B2B intent data category, supplying intent signals to platforms like Demandbase itself
• ZoomInfo: The largest B2B contact database, with detailed individual-level profiles
• Clearbit: Now part of HubSpot, providing data enrichment for sales and marketing
• Apollo.io: A sales engagement platform with a massive B2B contact database

Each platform has its own separate opt-out process, and each needs to be revisited periodically because B2B data re-collection is continuous.

Let PrivacyOn Handle It Automatically

Manually opting out of Demandbase, re-checking after cookie clears, and repeating the process across dozens of overlapping B2B data platforms is time-consuming and easy to neglect. PrivacyOn automates the entire process across 100+ data brokers, including B2B platforms like Demandbase, 6sense, and Bombora. When a broker re-adds your profile or when a cookie-based opt-out expires, PrivacyOn detects it and re-submits the removal request on your behalf. One enrollment covers continuous protection so you do not have to keep track of which platforms need a fresh opt-out.
