Startup for RISC-V?

I think I'm in a good position to start a startup. I have a family member that is good with business management stuff and legal aspects of all of this, I'm very young (19), have some disposable income but I would need to get some more for a startup and I have no expenses (living with family).

SiFive has been pretty successful but I it's not a realistic goal to compete with them. Is there something involving RISC-V that could be made profitable without an upfront investment that is > 100'000 EUR? From what I understand, Mikrotik, a company from my home country Latvia, became successful because they didn't limit their devices behind a license. I just don't know how to find opportunities like that to take advantage of. Why I'm asking about RISC-V specifically? Because it's something that interests me, the benefits of that ISA look promising and I assume there's less competition.

In summary, how do I find problems that could be solved by or technologies, services that could be improved upon by using RISC-V?
