Be well sourced with enough runway to become part of the local eco-system. Come prepared so you start ahead. Focus on the one goal you want to achieve. Forget about “fundraising by tourism”. People are not waiting for you with bags full of cash. Everybody is in the Startup/ VC/ Technology / Biotech and related services in Silicon Valley. You will meet folks randomly who might prove pivotal to your business. The more you network, the more you will benefit. There are multiple meetups per week/day in the area that are relevant to interest groups and ideal for networking. Organic is the best way to find contacts/partners/investors. Any imaginable leisure activity is a short drive around: hiking, horseback riding, parasailing, skiing, surfing, kayaking, swimming, pubs, restaurants. Great for networking.
