Silicon Valley is extremely expensive. You'll burn through a large chunk of your $100k on moving costs and rent and waste a ton of time -- Changing your home continent takes several weeks of preparation and can take several more weeks of toll in energy and post-move management).
IMHO, from your post it doesn't sound like you have the cash to afford this and found your startup. Don't do it; you don't have to, that'll give you a huge advantage.
