Brett Adcock’s latest venture, Hark, an AI hardware company, has raised over $700 million in a Series A funding round that values the startup at $6 billion. The round closed roughly two months after Hark publicly emerged from stealth, placing the company among the highest-valued AI hardware bets before it has delivered a single product to customers.

The funding was led by Parkway Venture Capital, and the investor list reads like a who’s who of the semiconductor and cloud computing ecosystem. Nvidia, AMD Ventures, Intel Capital, and Qualcomm Ventures all participated, alongside Salesforce Ventures, Brookfield, ARK Invest, Greycroft, Prime Movers Lab, Align Ventures, and Tamarack Global. The presence of multiple chipmakers on the same cap table signals a strategic alignment that could give Hark an edge in securing manufacturing capacity and technical partnerships.

Adcock founded Hark in late 2025 with $100 million of his own money, drawn from the proceeds of his prior entrepreneurial successes. His track record includes co-founding the recruiting marketplace Vettery, which was acquired by Adecco for $100 million; founding electric aircraft maker Archer Aviation, which went public via a SPAC merger in 2021; founding humanoid robotics company Figure, where he remains CEO; and founding school-security firm Cover. He also serves as principal at Hark, indicating deep personal commitment and financial stake in the venture.

The Vision Behind Hark

What Hark is actually building remains less clearly defined than the capital it has raised. The company describes itself as developing a “personal AI platform” that combines in-house foundation models, software, and custom hardware with new user interfaces. Unlike many AI startups that focus on a single layer of the technology stack — such as chips, models, or applications — Hark is attempting to vertically integrate all three from the outset.

According to a press release issued in March, Hark intends to release its first multimodal models this summer. These models are expected to process and generate text, images, audio, and video, forming the core of the platform that will eventually drive a dedicated hardware device. However, the company has not disclosed specific details about the device’s form factor, target price, launch markets, or customer pipeline.

This level of opacity is not unusual for a company only two months out of stealth and flush with cash. The $700 million Series A provides substantial runway to keep development plans under wraps while the team works toward a market-ready product. Industry observers speculate that the device could take the form of a wearable, a smartphone-like companion, or a stationary home hub — but nothing has been confirmed.

Market Context and Cautionary Tales

Hark is entering a category that has seen high-profile failures. Humane’s AI Pin, launched in 2024, became a cautionary tale when early reviews highlighted poor performance, overheating, and limited utility. Rabbit’s R1 device faced similar criticism, with users questioning its value proposition. Even Apple, which possesses unparalleled hardware distribution and integration capabilities, has spent the past year iterating on its on-device AI offering, with no clear breakthrough yet.

The challenge for hardware AI companies is twofold: they must deliver compelling software that justifies a new device, and they must ensure the hardware itself is reliable, affordable, and useful in daily life. Many startups have stumbled on either or both fronts. Hark’s approach of designing the model stack and silicon together from day one aims to avoid the integration issues that have plagued rivals.

Adcock’s track record includes shipping complex hardware at scale. Archer Aviation successfully brought electric vertical takeoff and landing (eVTOL) aircraft from concept to certification and production, while Figure’s humanoid robots have been deployed in real-world warehouse environments. This experience could be a decisive advantage in navigating the hardware development lifecycle, which typically spans several years and involves countless engineering obstacles.

Investor Confidence and Strategic Implications

The participation of Nvidia, AMD, Intel, and Qualcomm in the same funding round is notable because these companies usually compete fiercely in the chip market. Their willingness to invest suggests that Hark’s platform may be designed to be hardware-agnostic at some level, or that each investor sees a unique strategic benefit. For Nvidia and AMD, which supply GPUs for AI training and inference, a partnership with Hark could secure a captive customer for their latest chips. For Intel and Qualcomm, which produce edge processors and mobile SoCs, the investment may be a bet on future on-device AI workloads.

With these investors on the cap table, supply chain allocation — often a binding constraint for AI hardware startups in 2026 — becomes a problem Hark can address more comfortably than its peers. Chip foundries and advanced packaging capacity are scarce, and having the backing of major semiconductor companies could help Hark secure priority access.

However, the round does not solve the fundamental challenge of product-market fit. Several well-funded, well-credentialed teams have entered this space with promising prototypes only to discover that consumers are not willing to adopt a new device category without a clear, everyday use case. Hark’s timeline suggests that its first models will launch within weeks, but the device that translates those models into a sustainable business is still further out.

Adcock’s previous ventures all benefited from careful timing and deep technical differentiation. Archer entered the eVTOL market when regulations and investor interest were aligning; Figure entered humanoid robotics as labor shortages and automation demand surged. If Hark can similarly time its market entry with a compelling product, it could succeed where others have failed. But the path remains uncertain, and the company has yet to prove that its integrated approach yields a system that people actually want to use.

For now, Hark is a billion-dollar paper valuation built on a founder’s reputation, investor confidence, and a broad vision. The next few months — with model releases and hardware announcements — will determine whether that vision can become a reality.
