About
Dayda.

Dayda is a managed data marketplace connecting distressed and shutting-down startups with AI labs, enterprises, and model builders who need proprietary training data.

Two problems.
One market.

The Problem for Sellers

Data that disappears
during wind-down.

Startups that are shutting down have valuable proprietary data but no way to monetize it. Founders don't know what their data is worth, don't know who to sell it to, and face significant legal complexity if they try to do it themselves.

Without a broker, that data gets deleted during wind-down, destroying real value for founders, investors, and the AI ecosystem.

The Problem for Buyers

Proprietary data is
impossible to source.

AI companies need domain-specific, proprietary, human-generated data at scale. Web-scraped data is commoditized, while unique datasets command real model improvements.

Finding and vetting sellers is time-consuming and legally hazardous. No trusted centralized marketplace existed for high-quality, legally clean training data. Until now.

What Dayda does.

Dayda sits between sellers and buyers, vetting, listing, brokering, and closing every transaction.

What makes
Dayda work.

Legal rigor is the product

Every transaction at Dayda is clean, documented, and legally enforceable. We don't cut corners on provenance or consent. That's what makes us trusted.

Quality over volume

We list fewer datasets than a self-serve platform would. Every listing passes a vetting process. Buyers trust that when something is on Dayda, it's real.

Value for both sides

Sellers get value from an asset that would otherwise disappear. Buyers get data they can't find or collect elsewhere. Dayda earns only when both sides win.

The managed
listing model.

Dayda does not allow open self-serve listing. Every dataset on the platform has been vetted before going live. This is the core differentiator.
