[Crosspost] Looking for data about company ownership network

I was suggested that this might fit here, so I’m crossposting from datahoarders (lemmy.world/post/5267985)

I’m looking for a data archive of corporation ownership networks. For example, Alphabet owns Google, … and some metadata like when they are created/owned by Alphabet if possible. I was made aware of OpenCorporates but it doesn’t seem to have such data as far as I tried.

The comments on datahoarders suggest a few interesting options (littlesis, wikidata, SEC filing scraping). I wonder if the OSINT communities know more about potential tools and resources for this.

Thanks!
