Kimber Lockhart - CTO / One Medical at SaaStr Annual 2018 Big mistakes, little mistakes, costly mistakes, and strategic mistakes. This session will explore mistakes I made and those I narrowly avoided during my time scaling enterprise subscription products and services at Box and One Medical. We'll explore classic challenges like how to decide to build customer-specific functionality, how to let customers opt-out of changes and when to create process around interactions between sales and engineering teams.
