Hunter detected Lucene on 139 websites whose company address is in the United States. The count is rebuilt daily from Hunter's index.
Hunter's highest-ranked United States sites running Lucene. Sites we hold no publishable contact data for are left out.
The largest industries across all 139 websites, not only the ones listed above. Sites with no industry recorded are in none of them.
Hunter turns each of those domains into named contacts with email addresses, and Discover takes the same two filters — Lucene, United States — and adds company size and industry on top.
Sign up to reveal the companies139 is the number of ranked websites in Hunter's index that were detected running Lucene and carry a United States company address. It is a floor, not a vendor's customer list, and the address is where the business is registered rather than where the site is served from.
A detection describes what a site runs today, and a tag left in place after a team stopped paying still counts — so treat one detection as a lead to check rather than as a confirmed contract.
