Hark raises $700M Series A for secretive universal AI assistant

Hark, a stealthy AI startup founded by serial entrepreneur Brett Adcock, announced a massive $700M Series A round on Thursday, valuing the company at $6B post-money. The round was led by Parkway Venture Capital and included a consortium of big-name investors such as AMD Ventures, ARK Invest, Intel Capital, Qualcomm Ventures, and Salesforce Ventures. Adcock, who previously founded robotics company Figure.AI and electric aircraft firm Archer, launched Hark in late 2025 with $100 million of his own money. The company is developing what it calls an "agentic AI system" that acts as a universal interface for the digital world—a personal AI assistant that works across products and services.

Hark remains highly secretive about its actual product, but plans to release its first multimodal AI models this summer, followed by dedicated hardware devices. The company currently employs 70 people, including former Apple product executive Abidur Chowdhury as director of design. Hark runs a data center with Nvidia B200 GPUs, and plans to use the fresh capital to recruit top talent in hardware, product design, and AI research. Chowdhury noted that while rivals like Anthropic and OpenAI focus on coding tools, Hark is unique in building both the software interface and native hardware for everyday consumers. However, key challenges remain, such as providing sufficient personal context without violating privacy—a problem that wearables like Meta's glasses haven't solved.
