Hark, a hardware company for personal AI agents founded by Brett Adcock, has raised $700 million in Series A funding, achieving a post-money valuation of $6 billion. The funding round was led by Parkway Venture Capital, with participation from major industry players such as NVIDIA, AMD Ventures, Intel Capital, Qualcomm Ventures, and Salesforce Ventures. Initially founded with $100 million in seed funding, Hark aims to develop a universal human-machine interaction interface through proprietary models and dedicated hardware. The company plans to launch its first multimodal models in summer 2026, followed by personal AI hardware terminals. The $700 million will be used to expand GPU computing infrastructure and accelerate model development. Hark's team, currently 70 members strong, primarily operates on NVIDIA B200 GPU clusters and plans to expand to 200 members soon.
