David Perozo is a native of San Francisco who has been at the heart of the tech and venture capital industries for over 25 years.

"This story...dives into the wild eccentricities of the tech scene in the San Francisco Bay Area...and weaves in some genuinely thought-provoking philosophical questions. On top of all that, it’s simply a wildly entertaining romp that makes for a fun read."
