Hark, a San Jose-based AI lab that has barely shown the world what it is building, just landed one of the largest early-stage funding rounds in AI history. The company announced an oversubscribed Series A of over $700 million at a $6 billion post-money valuation -- before shipping a single product.
The bet behind the blank page
Founder and CEO Brett Adcock -- also the entrepreneur behind robotics company Figure AI and electric aircraft builder Archer -- launched Hark in late 2025 with $100 million of his own money to develop an agentic AI system that serves as a universal interface with the digital world. That self-funded start was not a side project. Before launching Figure, Adcock founded the data-driven online recruiting marketplace Vettery, which he sold to Adecco for $100 million, and Archer Aviation, an eVTOL aircraft startup that went public via a SPAC merger in 2021.
