October is conference season here in San Francisco and one of our favorite can’t-miss events is Rakuten Optimism. Held at the Bill Graham Civic Auditorium on October 23, Rakuten gathered 3,000 attendees to hear talks from the likes of Rent the Runway Co-Founder and Jetblack CEO Jennifer Fleiss, Google Chief Evangelist of Brand Marketing Gopi Kallayil, and many others to discuss the newest trends in digital innovation.
