The table above shows a sample of 54 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:

• Building Materials3.7037037037037033%
• Information Services1.8518518518518516%
• Software Development1.8518518518518516%
• Aviation and Aerospace Component Manufacturing1.8518518518518516%
• Recreational Facilities1.8518518518518516%

Building Materials leads that list. However, the long tail matters just as much. Adoption reaches 16 industries in total. So you can narrow the list to the segment you sell into.

The matched companies sit in 8 countries. These lead the sample:

• 🇯🇵 Japan 26
• 🇺🇸 United States 2
• 🇮🇹 Italy 2
• 🇨🇦 Canada 1
• 🇬🇧 United Kingdom 1

Japan 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.
