What is Data Marketplace?

A data marketplace is a platform that connects data sellers with data buyers, enabling the listing, discovery, purchase, and delivery of datasets. Unlike traditional data brokers who own all the data they sell, marketplaces operate as intermediaries — they provide infrastructure (hosting, payments, search, access control) while independent sellers supply the data. Data marketplaces range from enterprise platforms like AWS Data Exchange, Snowflake Marketplace, and Databricks Marketplace to specialized platforms like LeadsVault (lead databases), Datarade (B2B data), and SafeGraph (location data). The marketplace model creates network effects: more sellers attract more buyers, which attracts more sellers. According to the World Economic Forum, the global data marketplace ecosystem was valued at $2.1 billion in 2023.

Why It Matters

Data marketplaces democratize data selling. Before platforms like LeadsVault, selling data required building your own website, payment processing, access control, and delivery infrastructure. A marketplace handles all of that — sellers just upload data and set prices. For buyers, marketplaces provide discovery, preview capabilities, and trust through reviews and platform guarantees. The marketplace model lets niche data sellers reach buyers they'd never find through direct sales.

Examples

  • •LeadsVault lets sellers upload CSV databases that become interactive, searchable tables — buyers can preview, search, and filter data before purchasing, with Stripe handling payments
  • •AWS Data Exchange hosts 3,500+ data products from 300+ providers, including financial market data, satellite imagery, and healthcare datasets, with delivery via S3
  • •A freelance data collector sells a dataset of 5,000 newly permitted construction projects (scraped from city permit databases) on LeadsVault for $149, earning passive income from 30+ buyers
