In this blog post we're going to look at the top tech companies and startups in Silicon Valley by amount of money raised. We'll then slice and dice to see the top startups for each funding round stage like Series A, Series B etc. We're not going to include companies that have been acquired by other companies or companies that have satellite offices in the Silicon Valley area. The companies on these lists all have their headquarters in Silicon Valley.
It's worth noting that "Silicon Valley" isn't a real geographic place. Despite literally the most heavily traffic'd post on Employbl being "map of silicon valley companies" Silicon Valley is only a geographic term in the loosest sense. The term originates from the microchip days when defense spending poured into the area to make many in San Francisco very wealthy. This term originated before the internet but especially took off in the 90s. For the purposes of this post we're going to define Silicon Valley as existing in the following cities: Menlo Park, Mountain View, Palo Alto, Cupertino, Redwood City, San Bruno, San Jose, San Mateo, Santa Clara and Sunnyvale. Please note this completely excludes San Francisco. If you're interested in learning about the history of Silicon Valley, both the place and the term I recommend reading Margaret O'Mara's book called The Code. Without further ado let's look at the full list of top startups headquartered in Silicon Valley..

Series B companies headquartered in Silicon Valley
I feel like "Series B" stage companies aren't really startups anymore. The institutional finance is in. There will be leadership changes. Things will get "more legit".
