B2B Data Extraction & Verification–50k SA Contacts

@amirali0301

Hello, I can build this scraping/automation workflow for you and return the data in the exact structure you need. I’ve worked with Python, Selenium, Playwright, APIs, pagination, dynamic websites, data cleaning and large-scale extraction, so I can handle both the scraping and the processing side of the project. For your project, I can: Scrape the required data from your target sources Handle pagination, filters and dynamic content Clean and structure the extracted data Remove duplicates / invalid records Deliver the final data in CSV/Excel/JSON or your required format Build the workflow so it can be reused or automated if needed I can also scrape a small sample first so you can check the data quality before proceeding. If you send me the website/source + fields you need + expected output, I can review it and tell you exactly how I would approach it. I’m ready to start.

@denisSolution

Hi, I'm Denis, a full-stack developer specializing in data extraction and verified B2B database building. I understand you need 50,000 verified South African contacts across five decision-maker personas with genuine corporate emails and 95%+ deliverability. I've built similar systems where the real challenge isn't volume—it's ensuring quality at scale. Getting verified, deduplicated contacts with legitimate corporate emails that pass SMTP validation is what sets this apart. Here's my approach: First, I'll validate the entire pipeline using your 200-contact sample—scraping sources, email verification logic, deduplication rules, and data structure. Once approved, we'll move to full 25,000 contact batches. Your milestone structure works perfectly for catching issues early. Technically, I'll use targeted South African business data sources combined with real-time SMTP/MX validation (NeverBounce or ZeroBounce) to ensure actual deliverability. Strict deduplication logic prevents duplicates across personas and companies, and each record gets validated against company domains to eliminate personal emails posing as corporate addresses. Data source quality matters significantly. I'll build verification steps to cross-reference contacts and flag questionable entries before delivery. I'm ready to start immediately. Let's discuss the details. Thanks, Denis.

i can do it

@DeveloperStation

Hi, The 95% deliverability bar is the real constraint here, not the scraping. We'd run every address through real-time SMTP and MX checks before it goes in the file, and drop anything that risks a hard bounce or spam trap rather than pad the count. For South African corporate contacts that means catch-all domains need extra handling, since a catch-all passes SMTP but still bounces. How do you want those treated, keep with a lower confidence flag, or exclude? We build data pipelines and automation in-house, including an evidence-backed business development system with SendGrid and enrichment logic. BD Automation: internal AI-driven BD workflow tool. The 200 sample makes sense. Should personas map to exact job titles you list, or accept close variants? Adil

@arshman18

Hello, I see you're looking for a professional to help extract and verify 50,000 South African corporate contacts, focusing on specific decision-maker roles. This involves gathering accurate, deliverable corporate emails while ensuring they meet your quality standards. My approach to this project would include using advanced web scraping techniques to gather data from trusted sources, followed by thorough verification processes. I would leverage tools like NeverBounce or ZeroBounce to ensure each email is valid and deliverable, so you can trust the accuracy of your database. I understand the importance of delivering a clean, deduplicated CSV file and can assure you that I will maintain your specified persona breakdown while adhering to all quality requirements. Looking forward to the opportunity to work together. Best regards, Muhammad Arshman

@C0RETECHIES

Hi, You need a high-volume, highly filtered B2B lead extraction pipeline targeting 50,000 South African decision-makers across five specific personas. The operation requires strictly corporate domains, rigorous geographical filtering, and real-time SMTP validation to guarantee a sub-5% bounce rate, delivered in a structured 13-field CSV format. Technical approach: We will deploy an automated extraction workflow combining LinkedIn scraping APIs and B2B enrichment databases. The pipeline filters by location and persona keywords, extracts base records, and routes them through a deduplication engine. Emails are dynamically pinged against a bulk SMTP validation API to drop catch-all, generic, and hard-bounce addresses. Core modules: The system includes a persona-mapping module to standardize job titles into your 5 categories, a location verification filter checking both user profile and company operations, a multi-layer deduplication script limiting contacts per enterprise, and a formatting module for the final CSV output. Relevant systems: Automation Lead Generator (Multi-agent AI pipeline for business profiling, contact discovery, and confidence scoring) Implementation strategy: We will begin by generating the 200-contact sample batch to validate persona mapping and SMTP check accuracy. Upon approval, we will scale the extraction to process the first 25,000 records, followed by the final batch, applying strict global deduplication before handoff. Regards, Rohit

@lazarr4

Hello, I can build a targeted B2B contact database for South Africa by scraping corporate directories and validating emails via SMTP checks rather than buying lists or using generic scrapers. I built a similar system for a SaaS client—scraped 30,000+ contacts with 98% deliverability by combining LinkedIn and company websites. I’d approach this using a multi-stage pipeline: scrape LinkedIn and company sites for initial leads, then validate emails via SMTP checks to filter out invalid ones. The biggest improvement will come from dynamic validation to avoid false positives. This ensures the database is ready for immediate outreach with minimal cleanup. I provide two weeks of bug fixing and improvements after delivery to handle any edge cases. If we’re aligned, I’d be happy to discuss the project further. Thanks, Lazar.

@jordanrafael7

Hi - Jordan here "B2B DATA EXTRACTION & VERIFICATION-50K SA CONTACTS" , you need a verified database of 50,000 targeted South African corporate contacts across 5 specific decision-maker personas. I'd build a persona-driven scraper with domain-first enrichment, then run real-time SMTP/MX and duplicate controls so deliverability and overlap failures are caught before delivery. Each record will carry standardized titles, company/domain, verified corporate email, LinkedIn URL, location, industry, and headcount, with the 200-contact sample batch and 95%+ deliverability used as the acceptance test. What verification stack are you using for the final SMTP/MX pass on South African corporate domains? Looking forward to work with you

@petropankovdev

Your spec is precise, so I will be precise back: at the listed ceiling, 50,000 verified records is not deliverable by anyone who actually scrapes and validates them. The real cost of building and SMTP-verifying a record of this depth (13 fields, LinkedIn URL, South Africa only, corporate domain, deduplicated) is around 0.06 USD each. Anyone bidding the full 50k inside this budget is reselling an aged list, and aged lists are exactly what fails a 95% deliverability bar and a zero-hard-bounce rule. So I am bidding a paid pilot you can measure, then scale at a known rate: 2,500 verified contacts, one persona of your choice (I would start with IT Managers / Heads of IT / CTOs), the full field schema exactly as you listed it, South Africa only, corporate domains only, 2 to 3 contacts per company maximum, deduplicated across personas and companies. If it clears your quality bar, the remaining 47,500 run at the same rate and schema in scheduled batches. Verification is custom SMTP and MX logic, as your brief allows, run per address rather than through a bulk list-cleaner. You get the Email Status column plus the raw check result, so you can audit the 95% figure yourself instead of taking my word for it. Catch-all or inconclusive addresses get labelled as such, never padded into the count. Delivery is clean CSV and XLSX with a short coverage note per persona, so you know where the next 10k comes from and where the sourcing gets thin. Background: one completed project on this account, rated 5 out of 5, delivered on time and on budget. I have shipped a large-scale contact-harvesting job before, at tens of thousands of records: public-source harvesting, affiliation cleaning, deduplication and email validation. Outside client work I have 16 merged pull requests in third-party open-source projects, mostly a 197-star Go security tool, each reviewed and accepted by the maintainers. One question: should the personal LinkedIn URL be mandatory (that drops coverage and raises cost per record), or best-effort, keeping the row when the verified work email is solid?

Hi, I can help with the South African B2B contact research and database-building project. I’m comfortable working with structured data, web research, Excel/CSV, deduplication, and data-cleaning workflows. I can also use established data and email-verification tools, together with AI-assisted research, to systematically identify the required decision-makers and validate the records. My workflow would include: • Researching South African companies and the five specified decision-maker personas • Collecting the required fields and LinkedIn/company information • Filtering out personal and generic email addresses • Verifying corporate emails using an appropriate verification service • Removing duplicates and maintaining the requested company/contact limits • Organizing the final data cleanly in Excel/CSV • Providing the requested 200-contact sample first for quality review I would prefer to start with the 200-contact sample so you can evaluate accuracy, coverage, formatting, and verification quality before the larger batches. I’m also happy to work with your preferred tools or licensed databases if permitted.
