Lusha is a B2B contact-data and enrichment tool best known for its simple Chrome extension. It reveals verified emails and direct phone numbers for prospects while a rep browses LinkedIn or a company website, and enriches records in bulk or programmatically through an API. The product runs on a credit system, where each revealed email or phone consumes credits. Higher tiers add list building, CRM enrichment, and intent signals, but the fast one-click lookup is its real center of gravity and what most reps adopt it for. It is far easier to start with than enterprise platforms, friendly to smaller teams and individual reps who want accurate contacts fast without a heavy annual contract. A free tier and self-serve pricing keep the barrier low. Lusha sits among the generic databases that cover the usual B2B contacts and work fine when an ICP is broad enough to slice by region, revenue band, and industry code. Coverage and accuracy trail enterprise sources, so records often need a verification pass before outreach. At Nebor we choose the data source based on the client ICP rather than relying on one generic database. Where Lusha suits the target profile, we sometimes connect it as one source among many, letting it take a pass when a record is missing a phone or email. That keeps coverage improving and cost per match low. Leaning on any single database leaves gaps; stacking a few sources and routing the right one to the right field is what closes them.
