Capbase is an open-source, crowdsourced alternative to Crunchbase and Pitchbook for company and funding data, featuring admin moderation and automated ingestion from SEC EDGAR, SBIR.gov, and Wikidata. It uses a TypeScript monorepo with Next.js, NestJS, and Prisma, and implements a moderation workflow for community contributions. The project is particularly interesting for its combination of public data ingestion and community curation in a transparent, self-hostable package.

Target audience: backend developers, data engineers, startup ecosystem researchers
