Websites That Use Insider in 2026

We track 906 websites that use Insider in 2026. Those sites span 36 industries and 26 countries. The crawler re-checks each domain daily. So the count moves as sites adopt Insider or drop it.

Insider belongs to the Customer data platform category. Sites in that category tend to share a similar stack. As a result, they often share buying patterns too.

The table above shows a sample of 100 matched companies. Each row carries an industry, a country, and a live domain. You can search it, sort it, and export it.

Adoption is not spread evenly. Instead, a few industries account for most of the matched sample:

• Retail20%
• Apparel and Fashion9%
• Information Services7.000000000000001%
• Consumer Goods6%
• Information Technology and Services6%

Retail leads that list. However, the long tail matters just as much. Adoption reaches 36 industries in total. So you can narrow the list to the segment you sell into.

The matched companies sit in 26 countries. These lead the sample:

• 🇧🇷 Brazil 18
• 🇺🇸 United States 17
• 🇹🇷 Türkiye 11
• 🇻🇳 Vietnam 8
• 🇦🇺 Australia 6

Brazil is the largest single market in this sample. Because the country is stored per row, you can filter before you export. That keeps your outreach inside one timezone and one legal regime.

Start with the table above. Then follow these four steps to turn it into an outreach list:

1. Filter the sample. Narrow by industry or country until the rows match your ideal customer profile.
2. Export the domains. Share the page to unlock the CSV, or sign in for the full dataset.
3. Find the people. Run each domain through Domain Search to pull every work email behind it.
4. Verify before you send. Pass the results through the Email Verifier so your bounce rate stays low.

Working at volume? Push the whole export through Bulk Tasks instead, or call the Domain Search API directly from your own stack.
