Hark raises $700M Series A for a stealth bid at a universal AI interface
Founder Brett Adcock lands a $6B valuation as Hark readies multimodal models and dedicated hardware for a personal AI assistant.

Why it matters
A $700M Series A gives Hark uncommon latitude to try a rare full-stack play in consumer AI: train multimodal models and build dedicated hardware to run them. Brett Adcock has repeatedly chosen capital-intensive, vertically integrated paths; this raise suggests investors think that approach can produce a must-have assistant that works across apps and devices. For founders, it is a reminder that compute, supply chain, and design talent are now strategic levers, not line items.
Hark has raised a $700 million Series A at a $6 billion post-money valuation, the company told TechCrunch, to build what founder and CEO Brett Adcock describes as a universal AI interface for the digital world.
Adcock is not new to capital-intensive bets. Before Hark, he founded robotics company Figure.AI and the electric aircraft builder Archer. He launched Hark in late 2025 with $100 million of his own money to pursue an agentic personal assistant that works across apps and services. TechCrunch has previously tried to peek inside the effort in a March report, but Hark has stayed unusually tight-lipped about the specifics.
What Hark says it will ship
Hark expects to release its first multimodal models this summer. Those models are meant to power a personal AI platform that interoperates with existing products and services, with purpose-built hardware devices to follow. The framing is full-stack: Hark is developing both the models and the devices that will run them, with the goal of a seamless assistant that can act on a user's behalf across the digital world.
That universal-interface pitch is not new in AI, but few teams are committing to both model training and bespoke hardware this early. The company is still in stealth on product details, timelines, and pricing.
Who backed it
The round was led by Parkway Venture Capital and included Align Ventures, AMD Ventures, ARK Invest, Brookfield, Greycroft, Intel Capital, Prime Movers Lab, Qualcomm Ventures, Salesforce Ventures, and Tamarack Global, per TechCrunch.
It is a notable mix of financial and strategic investors. The presence of AMD Ventures, Intel Capital, and Qualcomm Ventures points to deep compute needs and possible hardware collaboration, while Salesforce Ventures signals enterprise interest if the assistant can integrate into existing workflows.
Hark said it will use the new capital to recruit across hardware, product design, and AI research, and to secure compute and components for training and devices.
Adcock's full-stack bet
Adcock has a history of taking on hard tech categories that require tight integration across software, hardware, and supply chain. Archer pursued a vertically integrated path in electric aviation; Figure.AI is building humanoid robots that combine mechatronics with modern AI. Hark follows that throughline into consumer AI, with the added twist of shipping both models and interfaces tuned for real-world use.
If Hark hits its summer milestones, the company will have a chance to show whether a vertically integrated assistant can stand out in a market dominated by software-only agents and phone-bound experiences. Until then, the size of the Series A and the bench of backers are the clearest signals of how much runway Adcock has secured to try.
