Brett Adcock’s AI Hardware Startup Hark Raises $700M at $6 Billion Valuation
May 21, 2026 – 4:56 pm
Two months after emerging from stealth, Brett Adcock‘s AI hardware company, Hark, has secured over $700 million in a Series A funding round valuing the startup at $6 billion. According to Bloomberg, this significant investment was led by Parkway Venture Capital with participation from prominent investors like Nvidia, AMD Ventures, Intel Capital, Qualcomm Ventures, Salesforce Ventures, Brookfield, ARK Invest, Greycroft, Prime Movers Lab, Align Ventures, and Tamarack Global.
Adcock, known for founding successful companies like Vettery, Archer Aviation, Figure, and Cover, initially funded Hark with $100 million of his own capital in late 2025.
Hark aims to develop a "personal AI platform" that combines in-house foundation models, software, and hardware with new interfaces. They plan to release their first multi-modal models this summer, according to BusinessWire.
Despite the impressive funding round, Hark’s path is challenging. The AI hardware market has seen several failures, notably Humane’s AI Pin and Apple’s struggles with on-device AI. Adcock argues that integrating models and silicon from the start increases product defendability.
However, Hark hasn’t disclosed details about its product, including headcount, form factor, target price point, launch market, or customer pipeline. This secrecy allows them to maintain some mystery while providing time to develop their offering. With Nvidia and AMD on the cap table, supply allocation concerns might be mitigated.
While the Series A provides significant resources, it doesn’t guarantee product-market fit. Hark joins a category with several well-funded teams that have struggled or failed to deliver. The company’s timeline suggests that its first models are imminent, but the path to a successful business is still uncertain.
