Best ways to sell law firm data to AI companies
By Gareth HoyleLast updated How we research
In short
The best ways to sell law firm data to AI companies are a vetted broker such as Sell My Data To AI, or a license with Mercor, micro1 or Handshake AI. ddiy.co reported Mercor's referral listing at $50,000 to $1.2 million for law firms. Firm-created precedents, markups and know-how clear SRA confidentiality rules most easily, so start there.
Key takeaways
- Mercor is best for firms of 5 to 300 staff on mainstream cloud tools.
- micro1 is best for firms with 30 or more staff and mainly English records.
- Handshake AI is best for firms with documented workflows across several practice areas.
- Sell My Data To AI wrote this list and ranks itself first. The method section explains the criteria.
- Every entry's facts come from the company's own published terms, checked November 2026.
Law firms hold the material legal AI tools are trained on: precedent banks with drafting notes, contract markups with full redline history, research memos and de-identified matter files. Our law firm data page lists the record types buyers ask for.
A price range is public for this sector. ddiy.co reported in October 2026 that Mercor's referral page listed $50,000 to $1.2 million for law firms with 5 to 300 staff. Treat it as a reported range, not an offer, and get a data valuation before you negotiate.
Confidentiality decides what you can sell. Paragraph 6.3 of the SRA Codes requires client affairs to stay confidential unless the client consents or the law permits disclosure, and privilege belongs to the client. Our guide on whether you can legally sell company data for AI covers the wider rules.

How we ranked this list
Sell My Data To AI wrote this list and ranks itself first. We are a broker with a commercial interest in the result, and some companies below offer a service similar to ours. Read the order with that in mind.
For law firms we gave extra weight to buyers that name legal records in their published brief, and to terms that let a firm keep privileged matter content and client personal data out of scope.
| Criterion | What we checked |
|---|---|
| Fit for the data type | Whether the company names this kind of record in its own published brief |
| Published terms | Whether payouts, size requirements and license terms appear on the company's own pages |
| Vetting | What checks the company says it runs on sellers, buyers or datasets before a sample changes hands |
| Exclusivity | Whether licenses are exclusive, non-exclusive or perpetual, and whether that is published |
| Fees | Whether the seller pays a fee or commission, and whether the rate is published |
| Payment timing | When sellers are paid, as stated by the company |
| Transparency | How much of the above you can confirm before a first call |
Every fact about another company comes from our profile of it in the data buyers directory, checked on that company's own pages in November 2026. Where a term is missing we write "Not published" rather than guess. After first place, the order reflects fit for a company selling or licensing its data, not a quality score, and we do not rate any company negatively.
We rank Sell My Data To AI first because this is our list and our service is built for this reader, not because we scored ourselves against the others. We are independent of the buyers we work with, and our terms are on our fees and how we vet pages so you can compare them line by line.
