SiFive has raised a total funding of $366M over 6 rounds and 9 years, which has been enough to give them leadership in the RISC-V ecosystem and a product range spanning virtually the entire range ARM's does -- from equivalents for Cortex-M0 (in fact lower) up to Cortex-X3 (and POWER9) for their latest core announced in October (P870, 18 SPECInt2l6/GHz).
