NoteQUA-650 retro-scan: The source is a biography of Marc Andreessen as an individual, not about Andreessen Horowitz (a16z) as an organization. Per QUA-648, a person and their company are different entities and count as MISMATCHES. While the source mentions Andreessen Horowitz and confirms Marc's role there, the primary subject is Marc Andreessen himself, not the firm.
