Brett Adcock, founder and CEO of humanoid-robotics company Figure AI, said on X today that his personal-AI startup Hark will launch its first product this week — and the first 100,000 registered users will get its paid plan free. He also opened a waitlist.

The announcement

Details are still thin — which, with Adcock, is on brand. Hark’s official site describes the product as a service that “help[s] users complete various tasks,” according to PANews, one of two outlets that reported Adcock’s post today. A RuntimeWire product roundup published the same day independently confirms the key terms: launch this week, first 100,000 sign-ups get the paid plan free.

The site itself is more ambitious. Hark.com says the lab is “building the most advanced personal intelligence in the world” — a system that “begins to think like you and sometimes, ahead of you to offload your mental workload.” The pitch centers on persistent memory, multimodal interaction (listening, speaking, seeing), and proactive behavior — the things Adcock has said today’s LLM chatbots lack.

The most-funded AI lab you still can’t see inside

Hark is no ordinary startup launch. Adcock introduced the lab in March 2026 after eight months in stealth, seeded with $100 million of his own money — he continues to run Figure alongside it. In May, Hark raised a $700 million Series A at a $6 billion post-money valuation, led by Parkway Venture Capital with a strategic roster that includes Nvidia, AMD Ventures, ARK Invest, Intel Capital, Qualcomm Ventures, Salesforce Ventures, Align Ventures, Brookfield, Greycroft, Prime Movers Lab and Tamarack Global, per IMP News.

That’s a staggering raise for a company that has shown almost nothing publicly. The bet, as far as outsiders can tell, is on a “universal interface” for the digital world: an agentic assistant that doesn’t just answer questions but acts across your software — aimed squarely at ordinary people rather than developers. While Anthropic and OpenAI chase coding workflows, Hark’s design lead is a former Apple product executive, and the company talks openly about bespoke native hardware devices built specifically for its models.

Handoff: the August preview

One clue about what launches this week: in August, Hark previewed Handoff, a browser-using AI agent, according to RuntimeWire. If this week’s launch centers on agentic computer use — an assistant that operates the browser and your apps on your behalf — it would land in one of the most contested lanes in AI right now, alongside Anthropic’s Computer Use, OpenAI’s Operator lineage, and a swarm of well-funded agent startups.

Why it matters

The consumer-assistant race is about to get its strangest entrant. Adcock has publicly said existing AI chatbots “feel incredibly dumb” despite years of progress — no long-term memory, no real personalization, no presence in the physical world. Hark is his answer: intelligence that knows you, remembers you, and eventually lives in hardware designed for it.

The open questions are the important ones: what the product actually is, what the paid plan costs (and therefore what “free” is worth), and whether a launch-week product can justify a $6 billion valuation. With the waitlist now open and the first 100,000 spots carrying free paid access, Adcock is betting that demand for a genuinely personal AI will answer the last question for him.
