I’m compiling a large-scale prospecting database and need BOTH sides of the equation: 100,000 United States-based websites and the senior executive behind each one, preferably the CEO. Here’s what I’m after: a clean, de-duplicated spreadsheet (CSV or XLSX) listing every domain alongside its matching executive record. At minimum the file should include the domain/URL, company name, and the executive’s full name and current title. If you can append verified business emails, phone numbers, LinkedIn profile links, industry tags, and location details, all the better and you’ll move to the front of the line. Accuracy matters more than speed; recent, verifiable data is essential. I will spot-check a random sample before approving final payment, so please rely on reputable sources, enrichment APIs, or your own proven scraping / data-collection pipelines. Deliverables • One master spreadsheet with 100,000 unique U.S. domains and their corresponding CEO or comparable top-level executive • A quick summary of your data sources and verification method I’m open to phased delivery—feel free to suggest logical milestones—but the full 100K record set should land in my inbox no later than four weeks from project start. If you have questions about field formats or validation thresholds, let me know in your bid; I’ll reply quickly so you can plan your approach with confidence.

Hi there, I understand you’re looking to build a large-scale prospecting database of 100,000 U.S. websites matched with verified senior executives (ideally CEOs), delivered as a clean, de-duplicated spreadsheet with high accuracy and verifiable sources. My approach will be to design a structured data pipeline using Python (BeautifulSoup/Scrapy) for web extraction, enrichment APIs (such as Clearbit, Apollo, or similar datasets where compliant), and LinkedIn/company registry validation where available. I would first build a domain ingestion and cleaning layer to ensure uniqueness and standardised company records, then run an enrichment workflow to identify firmographic data and executive leadership details. A secondary validation step would cross-check titles and names against official company pages, press releases, or trusted business databases to ensure accuracy. The processed data would then be normalised into a single CSV/XLSX output with clearly defined fields (domain, company name, executive name, title, plus optional enrichment such as email, LinkedIn, industry, and location). I would also implement batching and logging so you can track coverage, completeness, and verification sources throughout the build. Do you want to prioritise strict CEO-only matching, or allow equivalent top executives (Founder, President, Managing Director) where CEO data is unavailable? I’m ready to begin immediately. Warm Regards, Aneesa

Hello, I can help build and deliver a large-scale database of 100,000 U.S.-based companies matched with their CEO or senior executive information. My approach combines multiple trusted data sources, including company websites, LinkedIn, business databases, and enrichment platforms to identify current executive leadership and verify company-domain relationships. Each record will be deduplicated and quality-checked before delivery. The core dataset will include: Domain/Website URL Company Name Executive Full Name Current Title To maintain quality at this scale, I recommend phased delivery with milestone batches (for example, 10,000–25,000 records per phase), allowing validation and feedback before proceeding to the next batch. Before starting, I can provide a sample dataset so you can review data quality, formatting, and accuracy standards. My focus is on recent, verifiable information rather than recycled lists, and I perform duplicate checks and validation throughout the collection process. I am confident I can meet the four-week timeline and would be happy to discuss preferred field formats, validation requirements, and milestone structure. Looking forward to working with you.

Hi I can build a clean, de-duplicated U.S. prospecting database with 100,000 unique domains matched to CEO or comparable senior executive records. I have strong experience with Python, Selenium, BeautifulSoup, enrichment APIs, data validation, email verification, LinkedIn/company research, deduplication, CSV/XLSX formatting, and large-scale prospect list building. For projects like this, I focus on recent and verifiable sources rather than low-quality scraped lists. The main technical problem is matching domains to the correct current executive while avoiding duplicates, outdated titles, invalid emails, and unverifiable records. My solution is to combine reputable business data sources, public company pages, enrichment tools, validation checks, and structured QA sampling before final export. I can include domain, company name, executive name, title, LinkedIn URL, industry, location, phone, and verified business email where available and compliant. I will also provide a short source and verification summary so you can understand how the dataset was collected and checked. Thanks, Hercules

Hi, I can help build a clean, verified prospecting database with 100,000 unique U.S. websites matched to senior executives such as CEO, Founder, President, or Managing Partner where CEO is not available. I have experience with large scale data collection, scraping, enrichment, deduplication, Excel/CSV management, and validation workflows. For this project, I would use a phased process: collect U.S. company domains, enrich each record with company and executive data, validate titles and locations, remove duplicates, and deliver a clean master spreadsheet with source and verification notes. The final file can include domain, company name, executive full name, title, location, industry, LinkedIn profile, phone, and verified business email where available. I will prioritize accuracy and use reputable public sources, enrichment tools, and cross-checking before delivery. A phased delivery makes sense here, for example sample validation first, then batches of 25K records until the full 100K is complete within your four-week target. Best, Justin

Hi, I can build a clean prospecting database of 100,000 unique U.S.-based company websites with matching CEO or senior executive details. I’ll structure the spreadsheet with domain, company name, executive name, current title, industry, location, LinkedIn profile where available, and verified business contact fields if accessible from reputable sources. The data will be de-duplicated, formatted consistently, and checked for obvious mismatches before delivery. For accuracy, I would work in phased batches so you can spot-check quality early instead of waiting until the full 100K list is complete. I’ll also include a short source and verification summary covering how records were collected, cleaned, and validated. Best regards, Waqas Ahmed
