Round figures show recent activity, not Xontogeny's whole history. Rounds on record name 4 companies; its own site lists 25.

Rates come from what VCinfo has observed since observation_start. Firms tend to remove companies that closed, so early rates understate reality. A company leaving a portfolio page does not mean it closed or exited. An unreachable site means our checks failed, nothing more.
