SiFive was founded by the creators of the free and open RISC-V architecture as a reaction to the end of conventional transistor scaling and escalating chip design costs.


We believe that by bringing the power of open-source and agile hardware design to the semiconductor industry, SiFive reduces the cost to harness the performance and energy-efficiency of custom silicon to the smallest company, inventor, or maker, enabling a whole new range of applications.
