Good research deserves good data — at its heart.
Cor is Latin for heart. Cordata is built on the belief that good research deserves access to good data. We gather what is technically public but practically inaccessible, standardize it, and deliver it through a single transparent marketplace.
The Problem We Solve
Public research data exists — but it’s scattered, inconsistently formatted, and locked behind complex processes.
The Status Quo
- Data scattered across dozens of government portals
- Inconsistent formats, missing identifiers
- Private deals and opaque pricing
- Months of manual collection per dataset
- No standardization across sources
The Cordata Way
- One marketplace for hard-to-access datasets
- Standardized schemas and clear documentation
- Transparent, public pricing
- Instant access via API or CSV download
- Regular updates — no stale data
How We Work
Three stages turn raw public records into research-ready datasets.
Identify & Source
We identify datasets researchers frequently need but can’t easily access. We work directly from public sources — government registers, patent databases, official publications.
Gather & Clean
AI-assisted pipelines and data engineering gather, deduplicate, and normalize the raw data. We add entity linkages — matching records across sources using company identifiers.
Document & Deliver
Every dataset ships with schema documentation, source notes, and a methodology description for academic citation. Access via API, CSV, or JSON — whatever fits your workflow.
Our Data Sources
All data originates from official public sources. We make it usable.
DPMA
German Patent and Trade Mark Office — patent filings, inventors, assignees from Germany
EPO
European Patent Office — EU-wide patent data via Open Patent Services (OPS) API
Bundesanzeiger
German Federal Gazette — annual reports and financial disclosures of private companies
Insolvenzbekanntm.
Official insolvency announcements from all German courts, linked to firm identifiers
