$700 million. That's what investors poured into Hark, Brett Adcock's new AI startup, in a Series A round that values the company at $6 billion - before it has publicly shown what it actually builds.
Adcock founded Figure, the humanoid robotics company, and before that Archer Aviation, an electric aircraft startup. Hark is his first pure software bet, and he's describing it as a "universal AI interface" - though the company has said nothing concrete about what that means in practice.
A $6 billion valuation on a Series A is uncommon. Most Series A rounds close between $10 million and $100 million. This round is roughly the size of what mature companies raise in late-stage growth financing, which means investors are betting on Adcock's execution track record and the concept itself, not a proven product.
"Universal AI interface" suggests a layer that sits above existing AI models - something that connects or simplifies access to multiple tools rather than training a new model from scratch. Whether that's a new kind of AI operating system, a unified assistant layer, or something entirely different is unclear. According to the TechCrunch report, the company remains tight-lipped on specifics.
The secrecy is notable. Most startups at Series A stage are actively recruiting customers and showing demos. Hark appears to have taken the opposite approach: raise the maximum possible capital while saying the minimum. That strategy can work when a founder's reputation is the product, but it creates real risk if the eventual reveal doesn't match the valuation.
For anyone tired of juggling ChatGPT, Claude, Perplexity, and a dozen other tools, a well-executed universal interface could have genuine appeal. Whether Hark delivers that is a question $700 million will take a long time to answer.
