Each company is ranked on the first of these it has on record: its revenue over twelve months (a run rate or a year as published, or its last four quarters added up; an AI segment where the rest of its business is not AI data), then its newest valuation, then the money it disclosed raising. No company pays for a place.

Twelve months.
A run rate or ARR is the company's own annualised figure, often its best month times twelve; a year is the year it published. Where a company reports quarters or halves, the last four quarters or two halves are added up. Gross revenue of a human data company includes what it pays its experts.
Who is on it.
A company is on this list when its own pages say it does this work, read word for word. It is not on it because we chose it, and none pays to be here.
Your place, on your site.
Every ranked company has a badge of its place, kept current with this page: the address is /badges/rl-environment-companies/ followed by the company's id in its page's address, as in Mercor's. Link it to this page.
Pays companies for data.
"Through our introductions": it takes companies' data through AIData.Broker's introductions and pays us a referral fee when one goes ahead. That never moves its place: the order is the money on record. "Its own programme": a published programme for buying data. "Says it buys data": its own words, linked.
