Marc Andreessen — Notable For: Co-created Mosaic web browser (1993); founded Netscape (sold to AOL for $4.2B); co-founded Andreessen Horowitz managing $90B+ in venture capital; techno-optimist AI advocate opposing safety regulation

NoteThe source confirms most claims: (1) Mosaic co-creation in 1993 ✓; (2) Netscape founding ✓; (3) Andreessen Horowitz co-founding ✓. However, there are two issues: (a) The Netscape acquisition price is stated as $4.3 billion in the source, not $4.2 billion as claimed—a minor discrepancy (~2% difference, within rounding tolerance but technically contradictory). (b) The source does not explicitly state that Andreessen opposes AI safety regulation. The source mentions his 'Techno-Optimist Manifesto' and his criticism of Biden's AI policies (wanting to prevent 'a function of two or three large companies' with direct government regulation), but does not explicitly characterize his position as 'opposing safety regulation.' The source also does not provide current AUM figures for Andreessen Horowitz to verify the '$90B+' claim. The claim's temporal marker '(as of 2026-03)' cannot be verified against the source's content, which includes 2025 data but no explicit 2026-03 snapshot.
