A hacker breached Doublespeed's backend systems and attempted to use the company's phone farm—which deploys thousands of fake AI influencers on TikTok—to post mocking memes about a16z founder Marc Andreessen. This is the second known breach of Doublespeed, a venture-backed startup that generates AI videos and synthetic social media accounts. The incident underscores the security risks in companies automating social media manipulation at scale, and reveals a16z's investment in infrastructure designed explicitly to flood platforms with inauthentic content. According to the Bloomberg report in the search results, Andreessen and Ben Horowitz have simultaneously poured $25 million into an AI-focused super PAC, illustrating their broader push to shape both policy and information flows around artificial intelligence.
