We're guided by a set of principles that are foundational to our work and drive every decision:
User-first: We build things that people want. We invest time to understand our users and focus on adding value instead of extracting value.
High agency, high ownership: We're responsible for the pieces we own, end-to-end. We own every mistake, figure out what went wrong, and fix it. We don't blame anyone or anything else.
Urgency: This is a once-in-a-lifetime opportunity. We prioritize well, find ways to increase leverage, and move at an inspirational pace.
