What if technology could make us safer in the real world? That's the problem Andrew Frame, founder of Citizen, set out to solve. The Citizen app, which combines location information with 911 intelligence, is now used by over seven million people across 25 cities. Andrew is a serial entrepreneur and tech whiz who is creating a fundamentally new category: safety. Andrew shares why he considers Citizen a mission instead of a product, how he approaches the burden of responsibility for building tech that impacts our psychology, and why he opts for poetry and philosophy over business books.
