Oomira reconstructed a public YC world from YC's active company directory and fresher public sources. It checked 4,043 active company records and found where newer evidence changed the current answer.
Source: YC public company directory, active companies view. Checked against 5,972 fresher public source documents.
The point is not that YC was wrong. The point is that every source starts aging the moment it is published. Oomira keeps the old claim, the newer evidence, and the current answer together.
