Hark raises $700M Series A for AI hardware as Brett Adcock bets big on consumer AI devices

Hark Secures Massive Series A Funding for AI Hardware Push

Hark, the AI lab building models and hardware for a personal AI assistant, announced Thursday that it raised more than $700 million in Series A funding at a $6 billion post-money valuation 1

. Parkway Venture Capital led the mega round, with participation from Nvidia, AMD Ventures, Intel Capital, Qualcomm Ventures, Salesforce Ventures, ARK Invest, Brookfield, Greycroft, Prime Movers Lab, Align Ventures, and Tamarack Global 2

. The funding lands Hark in the upper tier of AI hardware bets before it has shipped a product, marking one of the largest early-stage investments in the consumer-focused AI product category.

Brett Adcock's AI Startup Builds on Serial Entrepreneur Track Record

Founder and CEO Brett Adcock launched Hark in late 2025 with $100 million of his own money to develop an agentic AI system that serves as a universal AI interface with the digital world 1

. Adcock is also the entrepreneur behind humanoid robotics company Figure AI and electric aircraft builder Archer Aviation, which went public via SPAC in 2021 2

. He previously co-founded recruiting marketplace Vettery, which sold to Adecco for $100 million. "We're building the AI that everyone deserves but no one has built yet -- one that actually knows you, speaks your language, is highly personalized, and lives on hardware made for you," Adcock said 3

Multi-Modal Models and Personalized Intelligence Devices in Development

Hark expects to release its first multi-modal models this summer, which it says will power a personal AI platform that works with existing products and services 1

1

. The company plans to follow that with personalized intelligence devices built specifically for those systems. According to Hark, the algorithms will feature a multimodal architecture and persistent memory that will enable them to save user preferences and proactively generate task suggestions 3

. A demo video indicates that Hark's AI models can reserve restaurant tables, make e-commerce purchases, and perform research, with support for voice commands 3

AI Hardware Development Faces Steep Competition and Privacy Concerns

The category Hark is entering is small, expensive, and littered with failures. Humane's AI Pin became the most public cautionary tale of 2024, with the Rabbit R1 close behind 2

. Abidur Chowdhury, a former Apple product executive who serves as Hark's director of design, noted that while Anthropic is prioritizing coding tools and OpenAI is moving in the same direction, few companies are focused solely on building interfaces and native hardware the way Hark is 1

1

. One challenge will be providing context of a customer's life to an AI assistant without making people around the user uncomfortable or violating user privacy 1

Compute Resources and AI Training Infrastructure Expansion

The fresh cash will be spent on recruiting top talent for hardware, product design and AI research, and on securing compute and components 1

1

. The company currently has 70 employees and runs a data center with Nvidia B200 GPUs, also known as Blackwell B200 graphics cards 1

. With Nvidia and AMD both on the cap table, supply allocation—often the binding constraint on AI hardware companies in 2026—becomes a question Hark can probably answer more comfortably than most of its peers 2

2

. Hark plans to use the funds to upgrade its AI training infrastructure and train the next generation of its models at the company's data center 4
