Andreessen Horowitz (a16z) has invested in Doublespeed, a startup that uses thousands of smartphones to create AI-powered fake influencers on TikTok and other platforms. The company, founded by 21-year-old Zuhair Lakhani, received funding through a16z's Speedrun accelerator program, which offers up to $1 million to young founders with early-stage ideas. Doublespeed's pitch is straightforward but provocative: replace human influencers with AI personas that never sleep, never demand payment, and can be customized to promote any product.

What Exactly Is Doublespeed Doing?

Doublespeed operates what Lakhani calls "the only venture-capital-backed bot farm in America." The company maintains a fleet of approximately 4,500 smartphones, with around 1,200 of them housed in a Los Angeles duplex and the remainder stored at off-site locations. Each phone is connected to a grid system of racks, USB hubs, and color-coded labels, all controlled remotely by artificial intelligence agents created by Lakhani's co-founder Hassan Syed, a 29-year-old software engineer.

The operation works in phases. When a client approaches Doublespeed with a product to promote, the company creates new social media accounts on TikTok and puts them through a "warm-up period" lasting one to two weeks. During this time, the AI agents control the phones to scroll through the app, comment on posts, and engage with content in a specific niche. If a client wants to sell tennis racquets, for example, the accounts will watch tennis content and interact with tennis-related posts. This creates what Lakhani calls a "trust score" with the algorithm, making the accounts appear legitimate before they begin posting promotional content.

Once warmed up, the accounts can post about the client's product. Because the accounts have already demonstrated genuine interest in the relevant niche, TikTok's algorithm is more likely to serve the promotional content to users who actually care about that category. The entire system is engineered to circumvent platform bot-detection systems, with each phone connected to its own device to avoid triggering algorithmic red flags.

How Does a16z's Investment Fit Into the Broader AI Startup Landscape?

Doublespeed's funding came as part of a16z's three-month Speedrun accelerator program, which launched in October. The program invests in what the venture firm calls "agentic" founders, meaning entrepreneurs who act decisively without waiting for permission and who pursue ideas that nobody explicitly asked for. Lakhani fits this profile: at 15, he was sneakerbotting, using code to purchase limited-edition shoes and resell them at a markup. Later, when his father's restaurant struggled during the pandemic, Lakhani manufactured artificial scarcity by announcing the restaurant was "sold out" before taking any reservations, then releasing reservation slots in limited drops every Wednesday at 4 p.m. Within two weeks, the waiting list grew to around 6,000 people.

The Speedrun cohort included other provocative AI ventures, according to reporting by 404 Media. Alongside Doublespeed were "the world's first AI-powered credit card," the "world's largest Netflix-quality AI streaming platform," and a "Bible-based AI buddy." Together, these startups formed what 404 Media called an "AI-generated hell on earth." Lakhani has leaned into this dystopian framing as a marketing strategy. His launch video features him peeling a digital mask off a woman's face to reveal himself sitting in front of a green-lit stack of phones, with the tagline "Never pay a human again" and a message that reads: "We didn't break the internet; it was broken to begin with. But now we're killing it entirely".

Why Is This Approach So Controversial?

Doublespeed sits at the intersection of several concerns about AI and social media. The company is explicitly designed to manufacture artificial virality, creating fake accounts that pose as real people. Lakhani's marketing emphasizes the dystopian implications: the company's website advertises the ability to create AI personas like "a 62-year-old mother in Phoenix or a Gen-Z skater in Atlanta" who will post about your product. These are not real people; they are AI agents controlled by the company.

Lakhani has acknowledged the ethical implications but framed them as inevitable. "I have no problem leaning into the dystopian feeling of our company. That's what brought us all this attention so far," he stated. He added that "a core belief of mine is that it's very hard to get attention as a new company nowadays. Even if you raise $50 million, no one's gonna write about you unless you're doing something crazy".

Steps to Understanding How Phone Farms Evade Platform Detection

• Trust Score Mechanics: Platforms like TikTok assign trust scores to accounts based on factors including the age of the phone, whether it was purchased in the target country, and the account's history of engagement. New accounts on wiped phones purchased outside the United States may receive lower trust scores and less algorithmic promotion to American users.
• Niche Warm-Up Strategy: Before posting promotional content, AI agents control phones to engage authentically with content in a specific category. This creates a pattern of behavior that makes the account appear to be a genuine user interested in that niche, increasing the likelihood that promotional posts will be served to relevant audiences.
• Physical Device Separation: Each phone is connected to its own device and controlled remotely, rather than running multiple accounts on a single device. This prevents the platform from detecting patterns of coordinated inauthentic behavior that would typically trigger bot-detection systems.

Zachary Thompson, who runs a 250-phone farm called Autoviral, explained the importance of these mechanics. "On any platform, you want to be cognizant of something called a trust score, which is basically how trustworthy your phone is," Thompson noted.

What Does This Mean for the Future of Social Media?

Doublespeed has not yet achieved its ultimate goal of completely autonomous AI accounts that can ideate, create, and publish content without any human intervention. However, the company claims to have built a waiting list of 6,000 companies interested in using its service within the first two months of launch. It bears noting that Lakhani has built his entire career on manufacturing artificial scarcity, so the size of the waiting list may reflect his marketing acumen as much as genuine demand.

The startup represents a new frontier in what some researchers call the "dead internet theory," the idea that much of what appears on social media is increasingly generated by bots and AI rather than real people. Lakhani's explicit embrace of this vision, combined with a16z's backing, suggests that venture capital is willing to fund companies that accelerate this trend, at least in the near term. Whether platforms like TikTok will continue to tolerate such operations, or whether regulators will intervene, remains an open question.
