Columns

  • company: Company name
  • website: Root domain, one row per website
  • linkedin_url: LinkedIn company page
  • industry: The company's own LinkedIn industry label

  • employees: Exact headcount, where we have it
  • city, state, country: Headquarters location
  • founded: Year founded
  • ownership: Investor-backed, Private, Public or Acquired, where we have it

There are no people or emails in this file. One row per company, and every company sits in exactly one of our 30 industry lists.

How good is it?

A company lands here because its own LinkedIn industry label says so. Spot checks put that right 85 to 90% of the time. We dropped companies without a website, ones marked out of business, and duplicate websites and LinkedIn pages. It is a good first cut of a TAM, and it is not verified row by row.

The list stops at the company. Turning it into pipeline means finding the right people, verified emails, and a reason to reach out now. That is what I build. Want this list with the right people and verified emails? Talk to me, or price it yourself with the TAM calculator.

FAQ

Is this list really free?
Yes. Enter your first name, work email and company and you get 1,000 of the 60,813 companies as a CSV right away, plus a copy of the link by email. To get all 60,813, answer three short questions after that. There is nothing to pay and no account to make.
Does the list include contacts or email addresses?
No. It is a company list: name, website, LinkedIn page, industry, size, location and founding year. If you want the right people at these companies with verified emails, that is the work OneGTM does, so reply to the email or book a call.
Where does the data come from?
Company records come from the People Data Labs Free Company Dataset (CC BY 4.0). Exact headcount and ownership come from a separate company database and are only attached when the name and size line up. We removed duplicates, dead companies and rows without a website.
How accurate is it?
A company is on this list because its own LinkedIn industry label says so. Spot checks put it right 85 to 90% of the time. Treat it as a strong starting point for your TAM, not a verified list.
Why do I need a work email?
The list goes to people building pipeline at a business, and we send a copy of the download link to the address you give. Personal inboxes like Gmail and throwaway addresses are not accepted.
