Is there a free open database of all companies/businesses in the world? If not, how would you go about building one, what would you need to do?

    Your approach would likely start at supporting the major countries. Australia, US (state-wise...), etc, and for all the work required it'd likely require remuneration to sell-on or make worth it. I once did a project for a specific state to capture business registrations, and I ended up having to learn how to parse old COBOL data formats, so the project would be scattered as far as resources would go. Write a generalized data capture library. Just some ideas.

    No, there isn't. Still, I think you should specify what data you need on those companies, as the question is a vague. Some data is available, but you need to clarify

    If you are part of the team behind companiesdata.cloud (I'm wondering with your name) you can add a disclaimer on the message.
