I've built a crawler that's indexed 51.3M+ companies and their technology stacks. I'm open-sourcing sample datasets (500 companies per technology) for the community. The repo covers 403 technologies across 30+ categories - CMS platforms, payment processors, frameworks, analytics tools, etc. Each CSV/JSON includes company name, domain, location, and detected tech stack.

These are free samples from my full database (which powers Leadita, my lead gen tool). The samples give you a solid starting point for:

- Market research and competitive analysis - Understanding tech adoption trends - Building prospect lists - Training ML models

Full datasets with contact info available via the platform, but these samples should be useful for experimentation and smaller projects.

The data updates daily. Feedback and suggestions welcome!
