Selling data
12 questions to ask any AI data buyer before you sign
Before you sign, ask any AI data buyer 12 things: who they are and who pays them, which AI labs get the data, the price in writing, when you are paid, whether the license is exclusive, permanent or passed on, who cleans the data, whether they need system access, how long they keep it, and whether past sellers were paid.1,2,3,4,5,6
The 12 questions
Print these out for the first call. Each one comes with what a clear answer looks like, using what buyers have actually published.6,7
- Are you the buyer, or a broker? Most company data advertisers are brokers. A clear answer names the company that pays for the data.1
- Who pays you, and how much? Pewter says its licensing partner pays it at close; Jottings says it takes typically 20-30% of your payout.8,9
- What is your legal company name and address? micro1 names a Delaware corporation. Some advertisers give no company name, address or terms at all.10,11
- Which AI labs will receive our data, and will you tell us? Sellers often cannot see the end buyer, so ask early.2
- What is the price, in writing, before anything leaves our office? Nyne's ads say the price is agreed first. SimpleClosure's CEO warns about buyers who want a full export before a real offer.3,12
- When and how are we paid? Look for a date in writing. Speeds vary, but it's usually around 3-6 weeks, sometimes longer.13,14,15,16,17
- Is the license exclusive, and for how long? micro1's is non-exclusive and perpetual. Polyshares says its licenses are exclusive by default. Troveo's exclusivity is time-limited.4,18,19
- Can you pass our data on to others? A sublicensable license, like micro1's, lets the buyer do that.4
- Who removes personal details, by what method, and do we see a sample first? Polyshares uses an outside firm. micro1 lets you review scrubbed samples. In the Spirit case, a firm certifies the result to the court.20,21,22
- Do you need access to our systems? One law firm says a buyer should get none. Mercor's process links to your tools, so ask exactly what it can read.5,23
- How long do you keep our copy, and how will you prove it is deleted? Nyne's ads say 30 days for raw files; micro1's terms say 120 days. Models are not deleted.24,4
- Have you completed and paid for a deal before, and can we speak to that seller? SimpleClosure tells founders to ask this. micro1 said in court that it did 50+ data deals in 45 days.6,25
Answers that should slow you down
A request for your whole archive before any number is mentioned. A website with no company name, no address and no terms. A domain registered last week. An example deal that also appears, word for word, on someone else's site.12,11,26,27
None of these proves anything on its own. Plenty of honest brokers are new. But each one is a reason to ask for more in writing before you share a single file.28
Answers that build confidence
Published terms you can read before the call, like micro1's data license terms. A named company and people, like Turing's Project Lazarus, which gives its company name and San Francisco address. An outside security audit, like the SOC 2 Type II report Mercor says it holds. And a willingness to put every answer above in the contract.4,29,30
Pros and cons
Pros
What it means for a business like yours
You do not need a lawyer to ask these 12 questions. You need a notebook and the nerve to wait for written answers. A good buyer will not mind. A buyer that pushes you to sign fast, or to send files first, has told you something.12
Keep the answers. If you sell the business one day, the buyer will ask about any past data deal, and your notes become part of that record.34
Should your business get in now?
Businesses are already licensing their records: micro1 has committed $1B over 12 months to buying company data, and at least 18 firms started advertising for it between September and mid-October 2026.35,1 Our view, not a promise: the money will not be around forever, because prices tend to come down as more businesses sell.35,36 Take the quiz to see which firms fit your business.
