The data your model needs is not on the open web.
Aribase sources private supply for AI teams: production code with real history, working documents, licensed media, and the step-by-step records of real companies operating. Tell us what you are training or evaluating, and we bring you matched, rights-cleared options.
How buying works
No public catalog and no self-serve checkout, by design: supply on Aribase is private, and most of it never appears anywhere else.
- 1
Specify
Modality, domain, scale, license shape, and what the data must do for your model. A one-paragraph brief is enough to start.
- 2
Match
We search current supply across all seven departments and source what is missing. You receive described, rights-checked options.
- 3
Evaluate
Review samples and documentation under NDA before committing. Sellers stay unnamed until both sides choose to proceed.
- 4
License
Negotiated terms per asset: exclusive or not, one-time or recurring. Delivery in the formats research teams actually use.
What buyers license for
Pre-training
Licensed corpora with the depth the open web cannot legally supply: whole archives, complete histories, and rights that survive diligence.
Post-training
Records of real work being done, step by step, so models learn how professionals actually reason, decide, and finish.
Fine-tuning
Narrow, expert material from a single domain, licensed to sharpen a general model into a specialist.
Evaluation and benchmarks
Held-out data no crawler has ever seen, which is the only honest way to measure what a model can do.
Supply across seven departments
Tens of thousands of assets tracked, with new supply arriving daily. If what you need is not in inventory, sourcing it is what our supply side is for.
