I need a fresh, well-verified list of 100,000 active websites belonging to U.S.–based companies that have between 50 and 500 employees. For each domain, include exactly one senior decision-maker—President, CEO, or Owner—so that outreach can go straight to the top. Please deliver everything in a single CSV file. Each row should contain: • company name • website URL (live and reachable) • employee count (source noted) • C-level contact name and title I’ll run random checks on at least 5 % of the list; entries that bounce, lead to parked pages, or list the wrong employee range will be rejected. Aim for a 95 %+ validity rate so we can move forward quickly. Use whatever combination of tools or datasets you trust—LinkedIn Sales Navigator, Crunchbase, Apollo, Hunter, BuiltWith, Clearbit, etc.—as long as the final file meets the above criteria. Let me know your estimated turnaround time and how you plan to keep the data clean and deduped.

Hello, I will extract approximately 50,000 company domains, along with their names and employee counts, from Apollo. I will also verify the domain statuses and retain only the live domains on the list. Please note that I am unable to include C-level contact names at this stage. Let me know if you would like to discuss this further. Duong

Hey, nailing that 50-500 employee count and ensuring a single senior decision-maker per domain is where I'd start. I'd use a combination of LinkedIn Sales Navigator and Apollo to filter and verify those specific criteria. The trickiest part is always the final validation to hit that 95%+ live domain and accurate contact rate, which I handle with multiple verification passes. Are you looking for a specific industry focus within the US companies?

Greeting! Building a 100,000-record verified dataset of US companies with accurate employee ranges and direct CEO-level contacts requires a compliance-first data aggregation and validation workflow to avoid invalid records, platform violations, and high bounce rates. We are a team of 62 professionals with over 9 years of experience in large-scale B2B data engineering, enrichment systems, and lead intelligence pipelines. Here’s how we can help: • Build firmographic filtering for US companies (50–500 employees) using compliant data providers and verified datasets • Enrich company domains with decision-maker mapping (CEO/President/Owner) from structured business intelligence sources • Validate and clean domains with live verification, deduplication, and removal of parked/inactive sites • Apply email/contact enrichment with verification layers to reduce bounce rates and improve deliverability • Structure QA sampling and accuracy reporting to ensure consistent dataset quality across all batches • Deliver a single consolidated CSV with standardized fields and traceable data sources Do you want to prioritize any specific industries or exclude certain sectors? Also, is outbound email outreach, LinkedIn outreach, or both the primary use case? We can build a scalable, compliant pipeline that produces high-quality lead data aligned with real outreach performance instead of unreliable bulk scraping.

Hi, I can help build a clean and well-structured database of 100,000 U.S. companies that meet your criteria (50–500 employees) and provide one senior decision-maker for each company. I have experience with large-scale data collection, web scraping, lead generation, and data validation. My approach would involve combining reputable data sources and implementing multiple quality checks to ensure high accuracy and minimal duplication. The final CSV can include: * Company Name * Website URL (verified and reachable) * Employee Count with source reference * Decision-Maker Name * Job Title (President, CEO, or Owner) To maintain data quality, I will: * Validate website accessibility * Remove duplicates and invalid records * Cross-check employee counts from reliable sources * Perform consistency checks before delivery * Deliver data in a clean, import-ready CSV format Because of the scale of this project, I would appreciate discussing your preferred sources, timeline, and any additional requirements before finalizing the scope. I can also provide a sample dataset first so you can review the format and quality. Best regards, Hasan

Hi, I build verified B2B contact lists at this scale, so a 95%+ valid rate is realistic for me. My plan: pull US firms with 50 to 500 employees from Apollo and Crunchbase, then cross-check each headcount against a second source and note that source per row. Every site is tested live with automated status and redirect checks so parked or dead domains never reach the file. For each domain I isolate one President, CEO, or Owner and verify the name and title against current company data. Dedup runs on normalized domain and company name, so no repeats slip through. Final output is a single clean CSV with company, live URL, employee count with source, and contact name and title. I deliver in 20k batches so you can spot-check early and I refine before the full run. Full 100k turnaround is roughly 12 to 16 days. I can send a free 500 row sample first so you can test quality against your own checks before committing. Thanks!

I’ve scraped and verified 50k+ US company domains at scale using Apollo, Hunter, and Clearbit in past campaigns, so this is right in my wheelhouse. I’ll pull from Apollo’s company export filtered by US, 50–500 employees, then cross-check live domains via HTTP 200/HEAD requests and filter parked pages using BuiltWith. Employee counts will be validated against Crunchbase or LinkedIn, and C-level contacts will be sourced from Apollo’s verified emails or LinkedIn Sales Navigator profiles. I’ll dedupe domains and contacts, run a 10% random SMTP ping to confirm deliverability, and deliver a single CSV with the exact columns specified. I can start immediately.

Hello! I would be a good candidate for this project because I live in the United States. I also have 100 companies around me physically that I know for certain meet the criteria needed for this project. Spreading farther than my town alone would complete the required 100,00 active website. I will keep the data clean and deduped with a spreadsheet.

Hi there, Maintaining platform compliance is incredibly important, and I completely agree with keeping all communication and verification strict. I will entirely remove any mention of external platforms like LinkedIn from our lead generation strategy and use alternative data aggregation tools to build and verify your target list. I will ensure our data collection process relies purely on internal B2B databases, programmatic scraping, and direct corporate domain analysis to source your high-accuracy list. I have two quick questions to make sure we're on the same page: Since we are bypassing traditional professional networks, would you like me to prioritize premium B2B data providers like ZoomInfo, Apollo, or Crunchbase to cross-reference the C-level executive titles? To ensure absolute data accuracy without external social tracking, should we implement a secondary MX record check on the company domains to verify that their corporate email servers are completely active? Let's discuss your project now!

Howdy! I want to be straightforward with you before you invest in this project, assembling a verified list of 100,000 U.S. companies in the 50 to 500 employee range with confirmed C level contacts and 95%+ validity is a significant data enrichment and verification operation, not a simple export. I have built Python ETL pipelines that pull, cross reference, and deduplicate records across sources like Apollo, Clearbit, Hunter, and Crunchbase APIs, then validate domains programmatically using HTTP probing and DNS checks. That technical side I can handle well. However, the sheer volume you are describing, 100,000 rows each requiring a live URL check, an employee count with a sourced citation, and a verified executive name and title, represents weeks of pipeline runtime, API credit costs that would be substantial, and ongoing human spot checking to hit your 95% threshold. I want you to have a realistic picture of what quality at that scale actually requires. Thank you. Marcos.
