A neutral marketplace square for data
In ancient Athens, the stoa was the covered colonnade beside the market square where merchants met buyers, compared goods and agreed deals. DataStoa does the same for data: a public place where any business can find who sells the data it needs, see real samples and prices, and talk to the provider directly.
Why we built it
Buying external data is still slow and opaque. Prices hide behind sales calls, samples behind sign-up walls, and marketplace fees behind contracts. We think the meeting place should be the transparent part.
- Free for buyers, always
- Search, contact, samples, requests and proposals cost buyers nothing.
- Published fees
- Provider plans, commission rates and attribution rules are public, with a worked example.
- Comparable listings
- Every listing uses the same spec sheet, so coverage, history and delivery line up.
- Demand you can see
- Buyer requests are public and anonymised, so providers come to you with a price.
- Plans never buy ranking
- Search order depends on relevance and quality, never on what a provider pays us.
- Data stays with providers
- We list metadata and masked samples. Contracts, payment and delivery stay between buyer and provider.
Trust and safety
A marketplace for data is only useful if buyers can trust what is listed. These are the checks we run.
Verified businesses
Every provider is a registered business we approved. The verified mark adds checks of registration, website ownership and rights to the data, with the date shown.

How we make money
Providers pay us: an optional plan for higher limits, and a commission on deals that started on DataStoa. Buyers never pay, and nobody can pay for a better position in search. That keeps our incentive simple: help buyers find the right provider.
