U.S.-Slovak start-up Tachyum (Rado Danilák) is developing a high-performance chip for data centers. The chip has just obtained engineering proof (i.e., it can be produced). The next phase will be software development in a new center it opened in Bratislava this summer. Danilák has sold his two previous firms, Sandforce and Skyera, and his multi-million euros exit is partly funding the new firm. It needs €30m for further development. Its investor is British-Slovak company IPM.
