Tachyum has been in the news time and again over the years, swinging wild promises that its Prodigy chip would leap over every existing design. The claims sparked all sorts of discussion, but Tachyum has a marginally more immediate inconvenience: not having an R&D center, after reportedly being kicked out of its Bratislava offices in the Slovakia over unpaid rent.

The firm's debts purportedly also extend to workers' wages and even social security plus health insurance, to the tune of 150,000 € ($178,000) on January 22. Tachyum reportedly owed 73,000 € already in December 2025. That was barely a month after it once again re-specced its Prodigy processor. This event followed a $220 million investment from an unspecified entity and a $500m purchase order from an unknown buyer.

According to Denník N news, despite the setback, the firm insists that it's still negotiating with investors and will eventually have resources to pay its debts, though it did not announce where it would move its operations to, if at all. As for the landlords and former employees, they'll reportedly be seeking legal action.

As the Bratislava offices were supposed to be the company's R&D department, it's now left with very little in the way of physical presence, seeing as its Las Vegas location is a virtual office, the Sunnyvale address is a shared space, and the Taiwan spot is likewise a virtual rental.

In a 2020 press release (archive link) that seems to have been selectively removed from its website in the past six months — as all other 2020 press releases still exist — Tachyum had said that the space was "7,000 sq. ft. of modern Class-A offices capable of accommodating 50 people, an internal datacenter, laboratory, Q&A; infrastructure and a supercomputer reference design site."

The company's Prodigy chip was announced in May 2018 for a tape-out the following year, but was the subject of repeated delays, ever-shifting specifications, and essentially a yearly revision of its release date and characteristics. Tachyum's performance and power efficiency promises are not modest. As of this writing, Tachyum's website still proudly claims its Prodigy will deliver a 21x speedup over Nvidia Rubin Ultra.
