Pan-Asia B2B Lead Database Build

I need a clean, well-structured B2B contact database that I can feed straight into my sales-outreach workflows. The target markets are Singapore, Malaysia, Indonesia, Philippines, Vietnam, Thailand, Hong Kong, Taiwan, Australia, China, and Japan. Within each country I’m interested in companies across Technology, Finance, and Healthcare, and I want coverage of every size category—from small businesses right up to large corporations.

Please capture, at minimum, the following in separate, clearly labeled columns:
• Company name
• Contact person’s full name
• Direct phone number
• Work email address
• Job title / position

Feel free to enrich each record with any other data points you can reliably source (company website, address, employee count, funding, LinkedIn URL, etc.). Accuracy is more important than sheer volume, so I will randomly verify a sample before final acceptance. Deliver the finished file in Excel or CSV; no PDFs.

If you already have access to reputable business directories, scraping tools, or paid databases, let me know—that will speed things up.

Do note that a sample of 40% of the dataset must be given for verification before project ends.
