Hark, the secretive AI hardware venture founded by Brett Adcock, just secured AT&T as both an equity investor and strategic partner for cellular connectivity and device certification. The deal represents a direct response to the connectivity disasters that derailed competing AI gadgets like Humane's AI Pin and Rabbit R1, locking in carrier infrastructure before the company launches its first product.

What Is Hark Building, and Why Does AT&T's Partnership Matter?

Hark's core pitch is straightforward: ship AI devices that connect directly to cloud services over cellular networks without relying on your smartphone's hotspot or home Wi-Fi. AT&T is providing both the cellular infrastructure and the regulatory scaffolding needed to get hardware certified and deployed across its network at scale. The carrier is taking an equity stake in the company as part of the arrangement, signaling confidence in Hark's product direction.

The timing is strategic. Humane's AI Pin became a cautionary tale in 2024 after launching with a T-Mobile-only cellular plan that added monthly costs and friction. Reviewers criticized the connectivity experience, and the device ultimately failed to gain traction. By locking in AT&T before shipping any hardware, Hark can integrate SIM provisioning and certification into its devices from day one rather than retrofitting connectivity later.

How Does Hark's Technical Stack Compare to Other AI Hardware Startups?

Hark has assembled one of the most complete pre-launch infrastructure stacks any AI hardware startup has built. In May 2026, the company raised $700 million at a $6 billion post-money valuation in a Series A round led by Parkway Venture Capital. The funding included backing from Nvidia, AMD Ventures, ARK Invest, Intel Capital, Qualcomm Ventures, and Salesforce Ventures, locking in chip supply relationships with three of the four major silicon vendors.

The company is training its multimodal AI models on a large cluster of thousands of Nvidia B200 graphics processing units (GPUs), working closely with Nvidia to accelerate development of its first-generation AI systems. Hark's models are also being trained on data from Figure AI, the robotics company also founded by Adcock, creating a data and compute moat that competitors cannot easily replicate.

Hark's team includes more than 45 researchers, engineers, and designers recruited from leading AI and technology companies. The hardware engineering talent comes from Apple, Tesla, and Meta, while design leadership comes from Abidur Chowdhury, a former Apple product executive. The company is designing multimodal end-to-end models, hardware, and interfaces in tandem, with a system that has persistent memory of your life and can listen, see, and interact with the world in real time.

What Are the Key Technical Capabilities Hark Is Targeting?

• Untethered Operation: Devices will operate completely independent of smartphones or Wi-Fi networks, connecting directly to AI backends over AT&T's cellular infrastructure.
• Advanced Network Features: The partnership covers what Hark calls advanced network capabilities, likely referring to 5G network slicing or low-latency edge computing features needed for real-time voice and vision processing.
• Persistent Memory and Multimodal Interaction: Hark's systems are designed to maintain long-term personalization of your life and handle natural speech, vision, and interaction out of the box, addressing what Adcock has described as limitations in current AI models.

How Does This Deal Reshape the Carrier Strategy for AI Hardware?

The AT&T partnership signals that carrier bundling is back in play for AI devices. Expect Verizon and T-Mobile to pursue their own equity-linked AI hardware bets rather than watching AT&T lock up the category. eSIM-first AI wearables also become more plausible if Hark ships with cellular baked in from launch, validating a distribution model that Humane botched and that Apple has only partially embraced with the Apple Watch.

The Adcock flywheel continues to accelerate. Adcock founded Figure AI in 2022, which announced funding at a $39 billion valuation in 2025. The data and compute overlap between Figure and Hark creates a competitive advantage that is difficult for rivals to match. However, a person familiar with the plans stated there is no intention to combine the two companies operationally.

What Remains Unknown About Hark's Product?

The obvious caveat is that no product exists yet. Hark has not disclosed a form factor, price, or launch date, and the AT&T deal is a commercial agreement rather than a shipping product. The company has stayed unusually quiet about form factor, only confirming that it plans to design multimodal end-to-end models, hardware, and interfaces in tandem. But the pieces Hark has assembled, foundation models trained on B200 clusters, silicon relationships with Nvidia, AMD, Intel, and Qualcomm, and now a national carrier as an investor and certification partner, represent the most complete pre-launch stack any AI hardware startup has put together to date.

Brett Adcock's track record with Figure AI, which reached a $39 billion valuation, suggests he has the capital and talent networks to execute on ambitious hardware visions. Whether Hark can avoid the pitfalls that derailed Humane and Rabbit R1 will depend on execution, product-market fit, and whether standalone AI devices can actually solve problems that smartphones and wearables cannot.
