Advaneo DataMarketplace vs Opendatabay

Advaneo DataMarketplace catalogs data offers and provides a portal for discovering, licensing, and exchanging data. It stores descriptions rather than providers’ raw data; after a buyer accepts a license and payment is confirmed, the raw data transfers directly from provider to buyer. Discovery includes text search, visual navigation, and machine-learning-based metadata recommendations. Metadata follows a standard based on IDSA standards, and the site says the platform and search support 16 languages. Providers can offer data free or commercially, set license terms and prices, and supply raw data after acceptance and payment. Payments currently support Mastercard and Visa credit cards. An IDS Connector can link file systems, databases, and sensor streams, while authenticated connectors exchange data with one another. Its cloud Workbench provides Jupyter Notebook and lists Python 3, Julia 1.0.1, R, and Ruby 2.5.1 support; common data science libraries are preinstalled and can be extended. The Free plan costs nothing and includes 15 MB of Workbench space and an IDS-Connector trial. Premium is listed at €2,950 a month, with an advanced yearly payment of 25 € monthly. Advaneo was founded in 2002 and is based in Düsseldorf, Germany.

Opendatabay is a marketplace for buying and selling datasets intended for AI and large language model use. Its listings span text, image, audio, video, code, agentic trajectories, 3D spatial, tabular, time-series, human feedback, and synthetic data. The documentation describes AI-powered search and recommendations, and says datasets are curated and labelled for model training or fine-tuning, with a claimed 20–40% reduction in preprocessing time. Buyers receive licensing terms and provenance information; the company says sellers undergo verification and due diligence. Both free and paid data products are offered, with provider-set prices for paid items. Sellers can list for free, while self-serve sales incur commissions ranging from 30% on sales of $1–$100 to 5% on sales of $250,001 and above. Registered users who complete onboarding can download evaluation samples, but production, commercial use, model training, and redistribution require a separate license or purchase agreement. The service is available on web and through an API. Only registered businesses, legal entities, or institutions may register as providers, and proof of business identity may be required.
