Voxel51 and its 13 ranked competitors
6 of them rank above Voxel51. 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.

- Who is a competitor.
- A company whose own pages, read word for word, say it sells at least two of the things Voxel51 sells. Not our opinion of who competes, and nobody pays to be here.
- The place.
- Each company's place among these, renumbered from its place on the whole register's ranking (/best), by the same rule.
- 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.
