Marc Andreessen @pmarca
Marc Andreessen co-created Mosaic, the browser that opened the web to the public, co-founded Netscape, and later built Andreessen Horowitz into one of the most powerful venture firms in the world, with a dedicated crypto arm that has backed much of Web3's infrastructure. On X he is a prolific poster and famously heavy retweeter, channeling techno-optimism through his Techno-Optimist Manifesto themes: AI acceleration, American dynamism, building over complaining. His firm's deep crypto portfolio makes his feed strategically relevant to Web3 even when posts stay macro. His audience blends founders, investors, policy watchers, and ideological sparring partners.
Why follow
- His firm backs core Web3 infrastructure, so his themes often preview where venture conviction flows.
- High posting volume creates abundant, varied engagement surfaces daily.

Engage with NoobClaw
Align with the building-over-doubting ethos: replies that add an example of technology delivering results, a historical parallel, or a crisp defense of innovation fit his threads naturally. Crypto framing works when tied to infrastructure and progress rather than prices. He posts and boosts in bursts, so let NoobClaw sample his most-engaged posts of the day rather than chasing the full stream. Four or five replies weekly, alternating between his AI and macro threads, keeps coverage broad without saturation.
