Hark raises $700M for a secretive universal AI assistant — but what is it building?

Hark, an AI startup founded by serial entrepreneur Brett Adcock, has raised $700 million in a Series A funding round that values the company at $6 billion post-money. The company, which has disclosed few details about its product, is developing what it calls a “universal interface” for the digital world — an AI personal assistant powered by its own models and hardware.

A massive bet on an AI consumer product

The round was led by Parkway Venture Capital and includes a long list of notable investors: Align Ventures, AMD Ventures, ARK Invest, Brookfield, Greycroft, Intel Capital, Prime Movers Lab, Qualcomm Ventures, Salesforce Ventures, and Tamarack Global. The sheer size of the raise — one of the largest Series A rounds in recent memory — signals strong conviction in Hark’s vision, even as the company has revealed almost nothing about its product publicly.

Adcock, who previously founded robotics company Figure.AI and electric aircraft maker Archer, launched Hark in late 2025 with $100 million of his own money. The company is building an agentic AI system designed to serve as a universal interface between users and their digital lives. Hark plans to release its first multi-modal models this summer, followed by dedicated hardware devices.

The team and timeline

Hark currently employs 70 people and runs a data center powered by Nvidia B200 GPUs. The fresh capital will go toward recruiting top talent in hardware, product design, and AI research, as well as securing compute and components. Abidur Chowdhury, a former Apple product executive, serves as Hark’s director of design. In a recent interview, Chowdhury said investors were impressed by internal demos but declined to share specifics about what the team is building.

“I haven’t seen anything that feels like something that will really help like the normal person,” Chowdhury said, referring to current AI products on the market. “People are really building things to help people make software, and it’s working, and it’s really impactful, but we haven’t really seen that for the normal person yet.”

He noted that while competitors like Anthropic and OpenAI are prioritizing coding tools and enterprise applications, few companies are focusing exclusively on building consumer-facing interfaces and native hardware.

Privacy and the wearables challenge

One of the biggest unanswered questions surrounding Hark’s approach is privacy. For an AI assistant to be truly useful, it needs context about a user’s life — conversations, habits, locations, and relationships. But capturing that context without making others uncomfortable or violating their privacy is a challenge that wearables like Meta’s glasses and the forthcoming Android spectacles have not yet solved.

When asked how Hark plans to address this, Chowdhury smiled and said, “Sounds like that would make a great product.” The company has not provided further details.

Why this matters

Hark’s massive raise comes at a time when the AI industry is increasingly focused on enterprise and developer tools. OpenAI is preparing for an IPO and leaning into coding assistants. Anthropic is building for software engineers. But the consumer AI market remains largely untapped beyond chatbots and image generators. If Hark succeeds in building a truly useful, privacy-respecting AI assistant with dedicated hardware, it could define a new category. If it fails, the $700 million question will be what went wrong.

For now, the company is betting that a combination of proprietary models, custom hardware, and design talent can create something that feels personal, not just powerful.

Conclusion

Hark has raised an extraordinary amount of money for a product that remains largely undefined. The company’s ambition — to build a universal AI interface for everyday people — is both compelling and risky. With a summer timeline for its first models and a growing team of experts, the next few months will reveal whether Hark can deliver on its promise or whether it will join the long list of well-funded AI ventures that failed to find a consumer market.
