Opendatabay review: can you list your company's data here?
Opendatabay fits a registered business with a clean dataset ready to list and sell on its own, and it is a poor fit for most internal company records, because its rules bar contact databases and anything under an NDA or confidentiality duty, and allow personal data only with a lawful basis you can document. If your data is email, CRM and files, our quiz shows buyers that take them. Listing is free, commission runs from 30% down to 5% on self-serve sales, and brokered deals grant perpetual licenses.1,2,3,4

Key facts
Opendatabay in its own words and others'
| Fact | Value and source |
|---|---|
| Opendatabay: who can sell | Only registered businesses, organizations or legal entities may supply data, and Opendatabay runs identity checks first |
| Opendatabay: commission | Listing is free. Commission is 30% on $1-$100, sliding down to 5% at $250,001 and above, on each transaction, so the seller keeps 70% to 95% |
| Opendatabay: brokered deals | The seller gets the agreed Provider Price within 14 days of cleared funds, and Opendatabay sets its own price to the buyer and resells |
| Opendatabay: brokered license | On brokered deals you keep ownership, but the license and every sublicense are perpetual and irrevocable, and non-payment does not revoke a buyer's license |

Is this for my business?
Opendatabay's category page and its rules point different ways
Opendatabay only takes registered businesses, organizations or legal entities, and runs identity checks first. Its enterprise category advertises CRM and project-management records, collaboration data, customer communications, business documents, and financial and transactional records.1,5
Opendatabay's Right to List rules then bar databases of email addresses, phone numbers or contact information, and data under non-disclosure agreements or confidentiality obligations. They also list financial information under personal and identity data without defining it, and allow other personal data only with a documented lawful basis disclosed in the listing. Our reading is that most company archives would fail those rules or need heavy cleaning first, and the seller agreement describes no help with exporting, cleaning or removing personal details.2,8
What would I keep?
Opendatabay's commission runs from 30% down to 5%
Opendatabay charges nothing to list, then takes 30% on sales of $1-$100, sliding down to 5% at $250,001 and above, so you keep 70% to 95% of each sale. The rate is set per transaction, not on your running total.3
Opendatabay also brokers deals, where you get an agreed Provider Price within 14 days of cleared funds, and it sets its own price to the buyer and resells. Self-serve payouts appear in the live fee schedule as [30] days after the end of the month with a [$50] minimum, and the square brackets were left in, so confirm both.9,6
Opendatabay's listings show asking prices, such as $999,999 for 76,000 hours of labeled coaching, sales and team calls, and no completed-sale figures are published, so an asking price tells you little about what sells.10
What do I sign?
What Opendatabay's seller agreement asks of you
Opendatabay's brokered deals leave ownership with you, but the license and every sublicense are perpetual and irrevocable, and non-payment does not revoke a buyer's license. For 12 months after delivery you may not grant anyone an exclusive license over those files.4,11
On brokered deals, Opendatabay has you warrant a valid lawful basis covering AI training and onward licensing, and keep records for at least 6 years. A later withdrawal of consent does not require retraining or deleting a model already trained, unless law requires it. Your liability is capped at 12 months of amounts paid or payable for a data product, but that cap does not cover your indemnity and warranties on brokered deals. Opendatabay indemnifies you against third-party claims from its own misrepresentation, payment errors or security failures. Its seller agreement offers no review of these terms with you, so what you would owe if a person in the data withdraws consent is yours to work out before you sign.12,7,13,14
Opendatabay's commission can follow a deal off the platform: it applies within 24 months of an introduced buyer's last purchase, or 12 months from first introduction if that buyer never bought. A sample download, enquiry, quote request or link through to your site is presumed an introduction unless you show with documents that the opportunity arose independently.15
