About Zephyr

AI can generate content for free. But the data that AI can't generate — data that requires real-world access, engineering investment, and verifiable sources — is becoming the real scarcity. Zephyr builds only the latter.

The Data That Matters

Not all data is created equal. The internet is flooding with AI-generated content, and the line between synthetic and real is blurring fast. Training data contamination is a documented problem. Licensing chains are fragmented. Provenance is often an afterthought.

We take a different approach. Everything we sell comes from one of two categories — and we tell you which is which:

■

Verified Real-World Data

Crypto exchange OHLCV, EIA energy statistics, public financial filings — data sourced from real-world systems that AI models cannot reproduce on their own. Multi-exchange aligned, outlier-filtered, with full provenance. Priced accordingly.

◯

Ready-to-Train Starter Packs

Synthetic datasets for local service businesses, niche industries, and specific use cases. You could build these yourself with a few hours of prompt engineering. We save you that time — and include a QA checklist. Priced as efficiency tools, not as exclusive insights.

This honesty isn't a weakness. It's how we build trust. When every data seller claims everything is "exclusive," the one who tells you which products are commodity and which are scarce is the one you'll come back to.

Our Standards

License

Every dataset comes with explicit commercial use rights. No ambiguous terms, no "check with your lawyer" clauses. If you buy it, you can use it in production.

Update Frequency

Static datasets ship with a published update schedule. API subscriptions include daily incremental updates. You know exactly how fresh the data is before you buy.

Provenance

Source manifest, processing pipeline, outlier detection log — we document where every data point came from and what happened to it. Built for teams that need to pass compliance reviews.

Format

Hive-partitioned Parquet by default. Drop into DuckDB, Pandas, or PyTorch without parsing CSVs or fixing encoding issues. AI-ready from day one.

Not Hype. Data.

The internet is full of digital nomad templates, AI prompt packs, and "build in public" content. We're not that. We build data products that quants, researchers, and AI engineers actually need — real datasets, real provenance, real value.

No fluff. No "10x your life" promises. Just data you can trust and build on.
