I am putting together a clean, fully-verified database of senior decision-makers and I need a researcher who can supply fresh, accurate records quickly. I am flexible on the seniority and industry mix—C-suite, directors, or high-level managers across technology, healthcare, finance or any other sector are all acceptable—as long as every record meets the quality bar outlined below. Expectations & scope I will provide you with a target company list or segmentation guidelines once we start. Using tools such as LinkedIn Sales Navigator, ZoomInfo, Apollo, Crunchbase or any other reliable source you prefer, capture both direct contact details and a brief professional profile for each executive. Deliverables (spreadsheet, CSV or Google Sheet): • Contact information: verified work email and direct phone number (no catch-alls, no generic lines). • Professional background: current title, key responsibilities or summary line, prior experience highlights and highest degree earned. • Source link for every datapoint so I can re-check if needed. • Date of verification. Acceptance criteria • 95 %+ email validity rate (I will run NeverBounce to confirm). • No duplicate records; consistent formatting. • Minimum of 100 executives per milestone unless we agree otherwise. Let me know your turnaround time for the first batch and the methodology you rely on to keep accuracy high.

My process includes cross-checking information across multiple sources, removing duplicates, maintaining consistent formatting, and documenting all references for transparency. I focus on delivering clean, reliable data that is ready for immediate use.

Hi, I build verified executive contact lists regularly and can meet your quality bar. My workflow layers LinkedIn Sales Navigator for role and profile capture with Apollo and ZoomInfo cross referencing for direct dials and work emails, followed by a two step verification pass, SMTP level checks plus a manual spot audit before delivery. That is how I keep validity above 95% on NeverBounce runs. Every record ships with a source link per datapoint, verification date, consistent formatting, and dedup keyed on email and LinkedIn URL. Profile summaries are written from actual career data rather than templated lines. For a first batch of 100 executives I can deliver in 3 to 4 days from receiving your target list, faster if the segmentation is simple. I can start with a 10 record sample so you confirm format before the milestone. Thanks!

Hello, 95%+ email validity rate – you need a fast, reliable way to collect senior executive contacts without duplicates. I’ll run every email through NeverBounce as I capture it and log the verification timestamp, guaranteeing the 95%+ validity threshold. To avoid duplicates I’ll dedupe by email and LinkedIn ID across sources, and I’ll include a concise title‑summary line for each executive – a format I’ve used for fintech and health‑tech lead lists. Which source do you prefer for the first batch – LinkedIn Sales Navigator or Crunchbase? Looking forward to working with you. Artur Giżycki

❤️ Hi! I understand what you're after — not just a big list, but a clean, verified one where every record actually holds up when you run it through NeverBounce. My methodology is built around that 95%+ bar. I source from LinkedIn Sales Navigator, Apollo and ZoomInfo, then cross-check each record across at least two sources before it goes in. Every email is run through a verification pass (Apollo/NeverBounce-style) to drop catch-alls and invalids, and I keep a source link and verification date against each datapoint so anything can be re-checked. Duplicates are removed and formatting kept consistent so the sheet drops straight into your pipeline. Alongside contact details I'll capture the profile fields you listed — current title, a short responsibilities summary, prior experience highlights and highest degree. I also keep the collection compliant with GDPR/CAN-SPAM, since that protects your outreach later. I've delivered verified B2B contact datasets like this before — happy to share a sample.
