Hark Raises $700M Series A at $6B Valuation for Personal AI Hardware

Hark, the stealth-mode AI hardware startup founded by Figure AI and Archer Aviation founder Brett Adcock, announced Thursday that it has closed a $700 million Series A round at a $6 billion valuation. The round was led by Parkway Venture Capital and included a long list of strategic investors that reads like a who's-who of the global semiconductor industry: Nvidia, AMD Ventures, Intel Capital, and Qualcomm Ventures all participated.

The size of the round is unusual for a Series A. So is the investor mix. Hark has not shipped a product, has not publicly demonstrated technology, and has spent the past several months operating in stealth. Yet it has now raised more capital in a single round than most AI startups raise in their entire lifecycle.

What Hark says it's building

Hark is positioning itself as a "personal AI platform" — a category the company defines as a stack of in-house foundation models, software, and dedicated hardware that serves as a universal interface to other AI services. The pitch, as described in interviews with Adcock and in the company's funding announcement, is that the current generation of AI products is fragmented across apps and devices, and there is room for one company to build the layer that ties them together.

The company expects to release its first multi-modal models this summer. The first hardware product has not been announced, but Adcock has said publicly that Hark is designing native devices rather than software-only experiences. That places Hark in the same broad category as Humane's defunct AI Pin and Rabbit's R1 device, both of which struggled to find product-market fit.

Why this matters: the personal AI hardware category has been a graveyard for ambitious startups. The Hark thesis is that the failures so far were execution problems, not category problems. The investors writing checks here are betting that thesis is correct.

The investor list is the story

The dollar amount is large. The investor mix is more interesting. Parkway Venture Capital led the round, with ARK Invest, Brookfield, Greycroft, Prime Movers Lab, Salesforce Ventures, and Tamarack Global participating alongside the chip-industry strategic investors.

Having Nvidia, AMD, Intel, and Qualcomm in the same round is rare. These four companies compete head-to-head across multiple silicon markets, and their venture arms typically do not co-invest. Their joint presence here signals that all four see Hark's hardware roadmap as relevant to their own product strategies, whether that means GPUs for inference, mobile chips for native devices, or custom silicon partnerships down the road.

Salesforce Ventures' participation is the enterprise tell. If Hark's product were purely consumer, Salesforce would have no reason to invest. The check suggests Hark has at least sketched out enterprise distribution as part of the long-term plan, even if the first product targets individual users.

Adcock's track record

Brett Adcock is one of the few founders who can credibly raise a $700 million Series A in stealth. He founded Figure AI, the humanoid robotics company that has raised at a $39 billion valuation, and Archer Aviation, the electric aircraft developer that went public via SPAC in 2021. Before that, he founded Vettery, a recruiting marketplace that sold to Adecco for over $100 million.

Adcock seeded Hark with $100 million of his own money in late 2025. That personal commitment, plus his prior track record, gave the round its credibility floor. Investors were essentially betting on Adcock's pattern-recognition for hardware startups rather than on a specific product roadmap.

The downside of betting on a founder rather than a thesis is well known. Founders can be wrong. The previous generation of AI hardware startups also had high-pedigree founders, and that did not save them from execution problems. The Hark bet assumes Adcock learned from those failures and from his own work at Figure and Archer.

Industry implications

For the AI hardware category, Hark's round resets the funding ceiling. Anyone building consumer or personal-AI hardware will now point to Hark's $6 billion valuation as a benchmark. That makes future raises easier for hardware-first startups, but it also raises the bar for what counts as a credible team and roadmap.

For Nvidia, AMD, Intel, and Qualcomm, the strategic value of the investment is optionality. Each company wants visibility into what next-generation personal AI devices will need from silicon. By co-investing, they each secure that visibility without committing to a specific architecture or design partnership yet.

For competitors like Apple, Samsung, and Google, Hark is a new variable. The big-tech players have native distribution and existing AI assistants. Hark's pitch implies it can build a better personal AI experience by starting from scratch on the hardware side. Whether that's true is the open question. If it is, the existing assistant landscape gets disrupted; if it isn't, Hark joins the list of well-funded hardware companies that did not find a market.

What insiders are saying

The reaction on X and in tech press has split along familiar lines. Founders and operators in hardware have largely been supportive, citing Adcock's record and the need for credible alternatives to phone-based AI. Skeptics have pointed to the long history of failed AI hardware startups and questioned whether $700 million is enough to bridge the gap between concept and consumer adoption.

ARK Invest's participation is notable. ARK has been public about its conviction in robotics and physical AI, and Cathie Wood's research team has written extensively about Adcock's other companies. The fund's presence here suggests Hark fits into the broader robotics-and-embodied-intelligence thesis that ARK has been building.

What's next

Hark has said the first multi-modal models will release this summer. The first hardware product has no announced timeline, though industry expectations are that some kind of device demonstration will happen before the end of 2026. The company has also said it will be hiring aggressively for engineering, design, and applied research roles.

The next watch points are concrete: which model does Hark release, what does the first device look like, and how does the company position itself relative to phones and existing AI assistants? Each of those decisions will tell us whether the $6 billion valuation is the start of a category-defining company or the latest entry in a long list of well-funded misses.

The bottom line

Hark has the founder, the capital, and the strategic investor mix to make a serious run at personal AI hardware. What it doesn't have yet is a product. The next twelve months will determine whether the $700 million Series A looks prescient or premature. The investors writing checks are betting on the former. Most of the AI hardware industry's history suggests betting on the latter.
