About Zephyr

Zephyr (zephyrdn.com) is a curated data product company. We build high-quality datasets, APIs, and AI tools for crypto researchers, quantitative analysts, and AI builders.

Why Data Products?

The AI era runs on data. But here's the problem: most publicly available datasets are noisy, inconsistent, and undocumented. Every researcher and builder wastes hours cleaning, aligning, and validating — before they can do any actual work.

We believe data preparation is infrastructure. It shouldn't be the first thing every team rebuilds from scratch. It should be a product you can buy, trust, and plug into your pipeline immediately.

That's what Zephyr builds. Curated, validated, documented datasets — ready for AI training, backtesting, and quantitative research.

Our Approach

Multi-Exchange Alignment

Every data point is benchmarked against a median price across multiple exchanges. Outliers flagged at 3% deviation. You get a single source of truth, not four conflicting numbers.

Full Provenance

Every dataset ships with a source manifest, audit trail, and compliance report. You know exactly where every number came from and how it was processed.

AI-Ready Format

Hive-partitioned Parquet files. DuckDB, Pandas, PyTorch — drop in and go. No CSV parsing, no schema guessing, no encoding issues.

Compliance First

NO-PII declarations, data lineage tracking, and institutional-grade documentation. Built for teams that need to pass compliance reviews.

Not Templates. 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 the kind of data products that quants, researchers, and AI engineers actually need — real datasets, with real provenance, at reasonable prices. No fluff. No "10x your life" promises. Just clean, reliable data you can build on.
