How Brett Adcock Built a Guaranteed Customer Before Selling Hark to VCs

Brett Adcock has a habit: he builds the demand before he raises the capital.

Hark, the AI lab Adcock founded in late 2025, announced a $700 million Series A funding round on Thursday at a $6 billion post-money valuation. Bloomberg reported that Parkway Venture Capital led the round, with Nvidia, AMD Ventures, Brookfield, Intel Capital, Qualcomm Ventures, and Salesforce Ventures participating. The round values Hark among the most valuable AI startups to raise a Series A in recent memory.

But the more revealing fact is how Adcock got here. He seeded Hark with $100 million of his own money before accepting a single external dollar, TechCrunch confirmed. And before the Series A closed, Figure AI, the $39 billion robotics company Adcock also founded, was already running Hark models in its humanoid robots, Business Insider reported. The Series A, in other words, was raised against a customer Adcock already owned.

That is bootstrapping in venture clothing. Traditional founders spend months convincing investors they have a path to revenue. Adcock simply gave the contract to himself, proved the model worked inside his own robotics fleet, and went to market with a demonstrated use case and a founder track record that includes two companies worth a combined $58 billion or more.

Hark is Adcock third major bet. He founded Archer Aviation, the electric aircraft company, and Figure AI, whose humanoid robots have become one of the most closely watched products in Silicon Valley. His estimated net worth is around $19 billion, much of it tied up in those two companies, Business Insider reported. He owns roughly half of Figure AI outright.

The $700 million will be spent on compute, hiring, and bringing Hark first multimodal models to market this summer, followed by purpose-built hardware devices, TechCrunch reported. The company has 70 employees and runs a data center powered by Nvidia B200 GPUs. Abidur Chowdhury, the former lead designer for the iPhone at Apple who most recently introduced the iPhone Air, leads design, BusinessWire reported.

The product vision is familiar in form: a personal AI platform that knows you, anticipates your needs, and operates across speech, text, and vision. But the distribution strategy is not. Most AI hardware startups launch a product and hope customers come. Adcock built the customer first, in a company he controls, then raised capital against that demand.

That matters for the broader AI hardware race. Hark is competing not just with OpenAI, which is building its own device family with former iPhone designer Jony Ive, but with Apple, Google, and Meta, all of which are developing AI gadgets, Business Insider noted. If Figure AI humanoid robots validate Hark models for real-world physical AI tasks, it is a proof point that no other AI hardware startup has yet produced. If they do not, the $6 billion valuation has no anchor except Adcock reputation.

Summer 2026 is the test. Hark models are supposed to ship then. Until they do, the $100 million Adcock put in is the most honest thing about this company.
