Scrape LinkedIn accountless with zero ban risk, target buyers with deep enrichment filters, and download clean, ready-to-use contacts at the lowest per-lead cost in the market. Start for free and stop buying leads twice.
Datacrecy SimpleXDatacrecy's answer
Datacrecy is the only B2B lead database that pre-verifies every email at the SMTP protocol level before it enters the database. Competitors sell you unverified data and make you pay a separate tool (NeverBounce, ZeroBounce) to clean it. We also run accountless LinkedIn scraping, meaning your LinkedIn account never touches our system and can't get banned. On top of that, we own the full pipeline (scraping, verification, enrichment, storage) which makes our per-lead cost the lowest in the market.
Datacrecy's answer
Three reasons. First, you stop paying twice. With Apollo you buy leads, then pay NeverBounce to verify them. With Datacrecy, verification is already done. Second, you get 2.5 billion contacts, which is 9x more than Apollo and 19x more than ZoomInfo. Third, accountless scraping means you can source LinkedIn data without risking your account. No competitor offers all three in one platform.
Datacrecy's answer
B2B sales teams, RevOps managers, lead generation agencies, and founders doing outbound. Companies that buy contact data regularly but can't justify enterprise contracts. People who care about cost per verified lead and bounce rates.
Datacrecy's answer
I was running a B2B lead generation company and spending thousands every month on Apollo for contacts and NeverBounce for verification. And emails still bounced because most verifiers use pattern matching, not real SMTP checks, Catch all, Mail trap. I was paying for the same lead twice and getting garbage half the time. So I built the scraping infrastructure, the verification pipeline, and the database myself. No middlemen, no rented data, no markup layers. That became Datacrecy.
Datacrecy's answer
ClickHouse for the contact database, Python for scraping and verification workers, SMTP protocol-level email validation, Docker for containerized deployment, and KumoMTA for mail transfer infrastructure.
