Semiconductor startup Tachyum has been forced to close its research and development office in Bratislava, Czech Republic, due to unpaid rent, wages, and taxes totaling over $178,000. Despite this setback, the company maintains it is still negotiating with investors and will eventually have the resources to pay its debts, though it has not announced where it will relocate its operations.
Why it matters
Tachyum has made bold claims about the performance of its upcoming Prodigy processor, promising a 21x speed advantage over Nvidia's Rubin Ultra. The closure of its R&D center casts doubt on the company's ability to deliver on these promises and raises questions about its long-term viability.
The details
According to reports, Tachyum owed 150,000 € ($178,000) in unpaid rent, worker wages, social security, and health insurance as of January 22, 2026. This followed an earlier debt of 73,000 € in December 2025, just a month after the company revised the specifications of its Prodigy chip. The company's other office locations, including in Las Vegas, Sunnyvale, and Taiwan, are either virtual or shared spaces, leaving Tachyum with limited physical presence.
- In December 2025, Tachyum reportedly owed 73,000 € in unpaid debts.
