Brett Adcock's personal-AI lab Hark has closed a Series A of more than $700 million at a $6 billion post-money valuation — one of the largest Series A rounds on record, and a remarkable mark for a company that has yet to ship a model or a device. The round was led by Parkway Venture Capital, with Adcock having seeded the company himself with $100 million when he launched the lab publicly in March.
A pre-revenue bet at scale
Hark is roughly 70 people and pre-product. It describes itself as building "an agentic AI system that serves as a universal interface with the digital world" — a stack that pairs in-house foundation models with custom hardware. The roadmap: ship the first multi-modal models this summer to power a software-only personal AI platform that plugs into existing apps and services, then follow with bespoke devices built around those models.
That sequencing matters. Rather than betting everything on a wearable out of the gate, Hark is fielding the model layer first and treating hardware as the second act. Training already runs on a company-operated data center built with Nvidia B200 GPUs, so the compute is in place ahead of the model release.
The investor list is the story
The cap table is unusually loaded with strategic silicon money. AMD Ventures, Intel Capital, and Qualcomm Ventures all participated — three rival chip camps writing checks into the same pre-revenue hardware company — alongside ARK Invest, Brookfield, Greycroft, Salesforce Ventures, Align Ventures, Prime Movers Lab, and Tamarack Global. For a device play, that breadth of semiconductor backing reads as an option on whichever architecture Hark's eventual hardware standardizes on, and as early positioning for design wins if a new consumer AI form factor actually lands.
Adcock's track record is doing heavy lifting on the valuation. He founded humanoid-robotics company Figure and electric-aircraft maker Archer, and before that the recruiting marketplace Vettery. Investors are underwriting a founder who has twice built capital-intensive hardware companies, not a shipping product.
What it signals for builders
The round is another data point that the "AI device" thesis still commands frontier-lab money even after high-profile stumbles in the category. Hark's order of operations — models first, hardware second — is the more defensible path: it lets the company build a usable platform on existing phones and laptops before asking anyone to carry new silicon.
For enterprise and infra watchers, the signal is the strategic-investor concentration. When AMD, Intel, and Qualcomm all back the same personal-AI hardware startup before launch, it suggests the chip vendors expect a new edge-inference form factor worth fighting over — and want a seat regardless of who wins. Whether Hark ships something the "normal person" actually uses, in the words of its Apple-veteran design director Abidur Chowdhury, is the open question the $6 billion price tag now has to justify.
