Large Corporation Contact Research

I’m building a fresh, fully-verified contact database of large corporations across Technology, Healthcare, and Finance in North America, Europe, and Asia. Your task is to visit each company’s own website or a reputable directory, capture the details directly, and cross-check everything for accuracy—no scraping of social media or third-party lead lists.

Here’s what I expect you to hand over:
• A spreadsheet (Excel or Google Sheets) with one row per company containing: company name, website URL, email address, telephone number, complete mailing address, and a short note on their key products or services.
• Zero duplication and no dead data; I will spot-check for bounced emails or disconnected numbers.
• A small pilot sample first, followed by the full batch once approved.

Please let me know:
1. How many fully verified records you can realistically deliver.
2. Your estimated turnaround time for both the sample and the complete dataset.

If you use standard research tools such as LinkedIn Sales Navigator, Crunchbase, ZoomInfo, or similar, feel free to mention them—just ensure every point of data traces back to an official source I can confirm.

Accuracy and consistency matter more to me than sheer volume, so build quality into your workflow. I look forward to reviewing your sample and moving ahead quickly if it meets the bar.
