The questions people ask
- Which AI data company is growing fastest?
- By the revenue on record: Snorkel AI, about $20M (run rate, Sep 2025) to $375M (run rate, Sep 2026), up about 19 times in 12 months. Then micro1, over $60M (run rate, Sep 2025) to $1B (run rate, Oct 2026), up to 17 times in 13 months, and Mercor, $500M (run rate, Sep 2025) to over $2B (run rate, Jun 2026), up more than 4 times in 9 months.
- How is growth measured here?
- Each company's newest twelve months of revenue on record against its figure about a year earlier on the same footing: two run rates nine to fifteen months apart, or two years, two twelve-month periods or two sums of quarters about a year apart. The change is what the two figures show, never extrapolated to a year. A run rate is often the best month times twelve, and a human data company's revenue includes what it pays its experts.
- Are these the fastest-growing AI companies overall?
- No: these are the companies that sell AI developers data, expert work, labeling, RL environments or evaluations, and only those that published two figures about a year apart (8 of the 18 with revenue on record). A company that publishes no revenue cannot be measured, so a fast-growing private one may be missing.
