## Summary

Hark, an AI startup backed by Nvidia and AMD Ventures, secured a $700 million Series A round at a $6 billion valuation in May. The funding round included investors like Parkway Venture Capital, Intel Capital, Qualcomm Ventures, ARK Invest, and Salesforce Ventures. Hark’s founder, Brett Adcock, is positioning the company as a competitor to Elon Musk’s Grok, which reached 800,000 paid weekly users in its third quarter, according to SpaceX’s data. Unlike Grok, Hark aims to develop its own foundation models, software, and AI-native hardware to create a personal assistant capable of managing tasks like scheduling, grocery ordering, and web automation—effectively turning AI from a tool into a hands-off delegate for daily work.

The endorsement from Adcock comes amid user frustration with Grok’s usage limits, prompting him to promote Hark’s subscription tiers as ‘incredibly generous.’ The semiconductor industry’s backing underscores Hark’s focus on building scalable AI infrastructure, aligning with the growing demand for capable, integrated AI assistants. With $6 billion in backing, Hark is positioning itself as a serious contender in the consumer AI space, leveraging its investor network to accelerate development.

## Key points

- Hark raised $700M in Series A at a $6B valuation, backed by Nvidia, AMD, Intel, Qualcomm, and Salesforce
- Grok reached 800,000 paid weekly users in Q3, per SpaceX’s data, while Hark targets broader AI assistant tasks
- Hark’s founder Brett Adcock promoted it as an alternative to Grok, emphasizing its subscription flexibility

## Why it matters

Hark’s $6B valuation and semiconductor backing signal a major push into consumer AI assistants, competing directly with Grok. Its focus on automation and integration could redefine how users interact with AI daily, while its hardware ambitions may influence AI infrastructure trends.
