Hark, an AI hardware startup founded by Brett Adcock, raises more than $700 million in a new funding round that values the company at about $6 billion. Multiple outlets report the round as Hark’s Series A, announced on May 21. The company describes its goal as pairing its foundation models with hardware to build what it calls a “universal interface between humans and machines.” TechCrunch and other coverage characterize Hark as operating on an AI chip-and-model approach, positioning it to connect model capabilities with specialized hardware. Bloomberg reports the valuation includes the newly raised funds. TNW notes that the company has been preparing its effort out of stealth and has developed a chip-and-model stack, with the funding round matching that direction. Across the reports, there is agreement on the core figures—over $700 million raised and a $6 billion valuation—and on the company’s stated focus on connecting foundation models to hardware for an interface concept.
