Former Google executive and billionaire Silicon Valley venture capitalist Chris Sacca, best known for being among the earliest and largest investors in companies such as Twitter, Uber, Instagram and Kickstarter, returns to the Tank as a guest shark. A husband and wife team from Palo Alto, CA has a device for babies to stay on track and parents to stay sane; entrepreneurial twins from Denver, CO have an online business that can ease the pain of paying for college; and a man from San Francisco has a tech solution to the dreaded parking ticket. Plus, a follow up on Rugged Races, the events company founded by Boston-based Brad Scudder and Rob Dickens, in which Mark Cuban invested during Season Five.
