Investors are an essential part of a startup. Without funding, it can be very hard to scale faster than any other company out there.

Over the past three months, I've been pitching my startup to countless investors. I've learned a few hard lessons along the way. First, not every investor is created equal. Second, just because someone's an investor doesn't mean he or she is right for your company. Third, your pitch deck title can make or break getting an investor's attention. Fourth, securing investment is possible in today's market.

Luckily for you, I've created a list of some of the investors I have found to be key in Silicon Valley. These are some of the top and most well-known investors not only in Silicon Valley but the world. I present them in alphabetical order (by first name).
