Hacker Compromises a16z-Backed Phone Farm, Tries to Post Memes Calling a16z the ‘Antichrist’
A hacker has compromised a backend system for Doublespeed, an a16z-funded startup that uses a phone farm to flood social media with AI-generated TikTok accounts, and attempted to have those accounts post memes calling a16z the “antichrist,” according to screenshots seen by 404 Media.The hack is at least the second time Doublespeed has been compromised. The startup uses AI to create fake influencers, generate videos, and post comments.
“a16z is the antichrist. sponsored by doublespeed.ai,” the meme says. It includes images of a16z co-founder Marc Andreessen; a woman pole dancing; and occult symbol Baphomet.

Do you know anything else about this breach or Doublespeed? We would love to hear from you. Using a non-work device, you can message Joseph securely on Signal at joseph.404 or Emanuel on emanuel.404.The screenshots show the meme queued up for publication in Doublespeed customers’ dashboard, seemingly to post to their associated social media accounts. A caption indicates the hacker stole some other data and may tried to post content from hundreds of accounts.
“47MB exfiltrated. 573 accounts postable. 413 phones dumped. A16z portfolio security built different,” the caption reads.

It appears the meme was ultimately not posted on Doublespeed customers’ social media accounts. One screenshot included the social media handle of an impacted Doublespeed account; as of Monday, the meme was not available on that account.Zuhair Lakhani, a co-founder of Doublespeed, told 404 Media in an email “We’re aware of the unauthorized access attempt and addressed it quickly. This involved an older system for queuing posts that had remained in place for compatibility with existing customer workflows, and we have since secured it.”
“Importantly, no unauthorized posts were successfully published, and we have not seen evidence that this attempt resulted in broader impact to customers,” he added.

404 Media first reported about Doublespeed last year, after the startup raised $1 million from a16z as part of its “Speedrun” accelerator program, “a fast‐paced, 12-week startup program that guides founders through every critical stage of their growth.” Doublespeed markets its use of phone farms as a way to evade social media platforms’ policies against removing inauthentic behavior. Doublespeed customers get access to a dashboard that allows them to operate multiple AI-generated influencers. At the moment Doublespeed focuses on operating TikTok accounts, but also plans to give customers the ability to operate accounts on X and Instagram.Doublespeed was previously hacked in December of 2025. The data from that hack revealed at least 400 TikTok accounts Doublespeed operates and that at least 200 of those were actively promoting products on TikTok, mostly without disclosing that they are ads or not real people. Some of the products promoted by these AI-generated accounts included supplements, massagers, and dating apps.
As we’ve noted last year, Marc Andreessen, after whom half of Andreessen Horowitz is named, also sits on Meta’s board of directors. Meta did not respond to our question about one of its board members backing a company that blatantly aims to violate its policy on “authentic identity representation.”
