Scope, evidence and limits
Description: Venture capital firm, named as “a16z” or “Andreessen Horowitz” in the cited funding announcements.
The records are grouped automatically. No human inspection of the selected claims, source paths or framing is recorded for this dossier. Each source passage shows how it was checked.
The dossier is computed from existing records. It is not a continuous history of the institution, and a missing record does not mean that an event or relationship did not happen. The chronology uses the dates of events and reports, not the date the public could first have known of them. Later sources can describe earlier events.
