Corporate.AI vs OpenCorporates
US-native. AI-native. Data sourced directly from Secretary of State filings — not scraped from third-party aggregators. The compliance-safe OpenCorporates alternative.
Why Choose Corporate.AI Over OpenCorporates?
US-Native, Built for US Law
Corporate.AI is purpose-built for the US corporate registry landscape. OpenCorporates covers 140 jurisdictions globally — the US is just one entry. For US compliance, that focus gap shows.
No Aggregator Legal Risk
OpenCorporates aggregates data through web scraping, which sits in a legal grey area for regulated industries. Corporate.AI pulls directly from official Secretary of State sources — clean chain of custody.
AI-Native from Day One
Corporate.AI was designed in 2024 for the AI-agent era. The MCP endpoint lets ChatGPT, Claude, and custom AI agents query the US corporate registry natively. OpenCorporates predates this paradigm entirely.

The Legal Risk Question
OpenCorporates aggregates data primarily through web scraping of government portals and third-party sources. For regulated financial services, insurance, legal, and healthcare industries, the provenance of KYB data matters.
Several compliance frameworks require data chain-of-custody documentation. Scraping-sourced data can create audit exposure for regulated entities.
Every entity record in Corporate.AI is sourced directly from the relevant state Secretary of State. No scraping. No third-party aggregation. Official government data with clear provenance.
For FDIC-supervised institutions, FinCEN compliance, or any regulatory audit, "sourced from Florida Division of Corporations" is a clean answer. Aggregator provenance is not.
Global Breadth vs US Depth
OpenCorporates: 140+ Jurisdictions
OpenCorporates covers 200M+ companies across 140+ jurisdictions globally. If you need to verify a company in Germany, Canada, and the UK alongside US entities, OpenCorporates has a single API for all of them.
Corporate.AI: Built for America
Corporate.AI focuses on delivering the most complete, accurate, and legally clean US entity data. 27.5M entities across 10 states today, expanding to all 50. For US-focused workflows, the depth and data quality advantage is significant.
Bottom line: If your primary use case is verifying US businesses — KYB, sales prospecting, legal research, or compliance — Corporate.AI provides more accurate, more complete, and legally cleaner data for the US market. If you need global coverage across dozens of jurisdictions, OpenCorporates has broader reach. Many enterprise teams use both: Corporate.AI for US compliance depth, OpenCorporates for international spot checks.
