Board and ownership data has been sold for twenty-five years. Here is what each of the established options does, what it does not, and where that leaves us. No straw men.
Two things nobody in that list does together: edges made of people and money rather than themes and supply chains, and a transaction-time stamp on every one of them, so the graph can be queried as it stood on any past date.
What we do not have: twenty-five years of history, or their coverage. We have public filings, in full, from the date we started recording — and we say so on every result.
