Selling a customer database: what AI data buyers do and do not buy
You heard AI companies pay for company data, and the first thing that comes to mind is your customer database. The buyers we work with say the opposite: they strip customer personal data out. What they pay to license is the work around the customers, how orders, complaints and questions got handled, and Polyshares has a third-party partner scrub personal data before anything is licensed.1,2
Not the database
What data buyers leave out
Names, emails, phone numbers and purchase histories are what buyers describe stripping out, and data held for clients and sensitive employee or health records are kept out of deals too. What remains is how your team works with customers: how orders were handled, how complaints were resolved, how staff were trained to answer questions.3,2,4,5
| Fact | Value and source |
|---|---|
| Personal data | A third-party PII partner scrubs data before it is licensed |
| Excluded data | Data held on behalf of clients is excluded |
| What SimpleClosure leaves out | Sensitive employee and health records are excluded; code, Slack, email and docs are in scope |
What they take
The service record built around the database
Buyers list email, chat, shared drives, CRM records, support tickets and call recordings among what they license. In a CRM, the useful part is the activity history and the notes, not the contact fields. A support desk's tickets, with personal details removed, show how a problem was found and fixed, and Ventra says support tickets and call recordings are in especially high demand.6,7,8
Published ranges for that record mostly run $100K to $2M, as the buyers' own claims. Treat that as a range, not a price for your company.9,10,11,12
Who your customers are is what a buyer of the business prices. What your team knows about serving them is what data buyers want, and a buyer of the business rarely prices it. The quiz asks your size and systems and introduces you to the buyers that take a company like yours.
When databases do sell
Customer data sales happen in distress, with the brand
The customer database sales on record come out of failures, sold with the brand. Zulily's trademarks, domains, customer files, social accounts and app code went for $4.5M in an assignment for the benefit of creditors run by Hilco Streambank. In RadioShack's bankruptcy, once states' objections settled, the buyer took only 7 of 170 data fields and two years of email. Those are context for how customer data is treated when it moves, not a price for yours.13,14
Appraisers value lists in M&A too: Tiger appraises customer lists and routes and revenue-generating databases. That is a valuation of the relationship, priced as part of the business.15
