I asked https://workplace.stackexchange.com/questions/119000/is-there-public-databases-about-subsidiaries-of-companies/119002#119002 on The Workplace, but apparently, it's not the right place and I'm off-topic.
I have a list of suppliers I need to consolidate. I want to make explicit that company A is a brand or a subsidiary of company B.
I tried to see if Wikimedia or other public sources listed on Google Dataset have a structured database with this information, with poor results.
I imagined a well-done JSON with nested relations between companies would be easily available, as it is public information in most cases and it will be useful to a lot of people, but I wasn't able to find any. Maybe I didn't know where to look.
Is there such a database listing companies and their subsidiaries and/or their brands? Is there any that are free? Is there any that are open?
Where should I ask this question?
