Ask HN: Is there a publicly available database of org charts?

Looking for org charts per year for companies as they grow — interested in seeing what roles and functions are added when, etc. I've found some old Apple charts via Computer History Museum and Internet Archive, but it seems like there should be an open source project to collect these, if there's not already.

Thanks! Hoping to drill into even the operator level, but those will be harder to source / vet. Will dig into SEC and related resources.
