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

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.
