Their value proposition is basically that you can get to market with a costum chip cheaper then with anybody. They argue that their chips are lower energy then use less space. They are more configurable, and the RISC-V tooling is build around this as well. They do seem to quite a few costumers but their current growth is VC funded. There is nice stuff coming down the pipe as well, the RISC-V Vector extension and hopefully finally some linux boards. RISC-V SoC with FPGA is going to be a product. But hardware product cycles are just long and a takes a while.
