Mistakes That Kill Deals — All of Them Made Before Negotiation Starts
The expensive mistakes in this market happen early: assuming a headline ceiling is your price, granting a first look before other buyers have bid, counting records you do not have the right to license, and sending files before anyone has signed anything.
SellMyDataForAI.com helps U.S. companies with 20+ employees license their operating records — email, chat, CRM and project data — to AI labs and training-data buyers. Owners keep ownership of their data; valuation starts with a metadata-only manifest, and no raw data is shared to get an estimate.
Mistake 1: Planning around the ceiling
Published ceilings ($3M+, $4M+) describe the largest, most unique archives. The documented median public sale is about $31,600 against a median published offer of about $280,000 (AIData.Broker compilation, checked November 2026). Budget on evidence, negotiate for more.
Mistake 2: Exporting data early. No legitimate step before a signed license or an NDA sample requires your files. Exporting early creates risk and zero leverage.
Mistake 3: One buyer, one price. A single application produces a single take-it-or-leave-it number. The same manifest shown to every buyer you fit produces a market.
Mistake 4: Counting records you can't license
Client-confidential files, privileged material and records your contracts reserve are found in diligence. A manifest that counts them gets repriced or rejected; one that excludes them up front gets trusted. Run the rights check first.
Mistake 5: Drifting into exclusivity. Some programs are exclusive by design. Signing before comparing means the premium for that exclusivity was never tested.
Mistake 6: Ignoring platform terms. Export and training-use terms in your tools are part of diligence. Surface them early; buyers structure around known restrictions.
Mistake 7: Skipping counsel. The license is the deal. A broker's summary — including everything on this site — is not a substitute for your lawyer reading it.
Do you qualify? The 90-second fit check
The introduction service on this site is built for U.S. companies with 20 or more employees, 3 or more years in business, and records in 5 or more systems — such as email, chat (Slack or Teams), shared files, a CRM, support tickets, project tools, or accounting software. Individual buyers set their own floors, which may be higher (for example 30+ or 50+ staff) or lower for specific industries, and each buyer’s own floor controls for its program.
Fit floor (published): 20+ full-time staff · 3+ years of records · 5+ data sources (email, Slack/Teams, Drive/SharePoint, CRM, support, QuickBooks, calls, code, project files). The interactive checker loads here; if it does not, the interview itself runs the same check in seven minutes.

Questions owners ask first
Is this a sale or a license?
A license. You keep ownership of your records and keep using them in your business. A buyer pays for the right to use a de-identified copy for AI training, on terms — length, exclusivity, permitted use — that you approve before anything is signed.
Do I have to send my data to get an estimate?
No. The estimate and the first call use only what you describe: systems, years and rough counts. Buyers bid on a metadata-only manifest. Full data moves only after you sign a license directly with a buyer, and personal data is de-identified before transfer.
What does it cost me?
$0 upfront. There is no retainer and no listing fee. We are paid a success fee only if a deal closes — the terms are stated in writing before any submission is made.
