Community Data vs ITjuzi

Community Data is a free, open database of more than 1 million people and companies, initially focused on the startup ecosystem. Its records are collaboratively maintained in an open-source repository as JSON documents that follow JSON Schema definitions. Schemas cover people, companies, locations, sectors, funding stages, and curated collections. A public GraphQL API lets developers query the data and build applications.

Anyone can contribute by creating or editing a JSON file. Commits are checked against the matching schema, and invalid documents cause a commit to be rejected. A proof-of-concept Next.js editor uses the GitHub API and requires contributors to authenticate with GitHub. Enhancer scripts can use public APIs or websites to structure information for the schemas and import it. Verified document owners are recorded by GitHub username, and their pull requests are automatically merged without review. Schema changes are proposed by pull request and reviewed by core contributors during monthly governance calls. The project uses the MIT License, copyright 2025.

ITjuzi is a China-focused venture investment data service that collects and analyzes publicly available information. Its coverage includes investment events, Chinese companies, VC investors, and news related to investment data; the company says it updates the data daily. Analysis combines equity transactions, company operating information, and news intelligence to examine industry trends, financing rounds, and investor comparisons. Users can download company, investment-event, institution, and report data using Juzi coins. Juzi Radar monitors selected companies, institutions, and industries, and the guide says users can follow three of 18 industries. The service also offers an API, though its use requires a team with technical engineers. Custom data can be delivered as Excel, CSV, MySQL, or JSON, with incremental updates scheduled daily, weekly, monthly, or quarterly. ITjuzi is available on Android, iOS, web, and through an API. A free plan is listed; paid memberships cost 108 CNY a month, 298 CNY, paid once, or 798 CNY, paid once, each with a specified Juzi coin download allowance.
