The proprietary
training data you
can't find elsewhere.
Web-scraped data is commoditized. Dayda sources domain-specific, human-generated datasets from startups that are shutting down. Data that exists nowhere else.

Buyer FAQ.
How is Dayda different from data brokers like Snowflake Marketplace or AWS Data Exchange?
Dayda is a managed marketplace specifically for proprietary startup data, not commodity data or API-delivered data products. Every listing has been individually vetted for legal provenance, quality, and compliance. We source data that isn't available anywhere else.
Can I get exclusive rights to a dataset?
Yes. Many sellers are open to exclusive licensing at a premium, typically 3–5x the non-exclusive price. Indicate your licensing preference when expressing interest and Dayda will negotiate accordingly.
What's covered in the Data Purchase Agreement?
The DPA covers data ownership and transfer, licensing terms (exclusive vs. non-exclusive, permitted use), warranties and indemnification from the seller, restrictions on redistribution, and dispute resolution.
What if the data doesn't match the listing description?
That's what the sample period is for. If you find a significant mismatch between the sample and the listing description, Dayda will not force the deal to close. We investigate and either resolve the discrepancy with the seller or take the listing down.
Can Dayda source specific data types you don't have listed?
Yes. If you have specific requirements not covered by current listings, reach out and describe what you need. We can discuss whether we're able to source it.
