From https://en.wikipedia.org/wiki/Santa_Clara%2C_California
“Santa Clara is located in the center of Silicon Valley and is home to the headquarters of companies such as Intel, Advanced Micro Devices, and Nvidia.”
So I think you shouldn’t try to convey the idea of “startup” with the metonym “Silicon Valley”. More generally, I’d guess that you don’t really want to write for a tiny audience of people whose cultural references exactly match your own.
