Our Culture
The values that define how we work together and build products.
Ownership Mentality
Everyone acts like an owner because everyone is an owner. Take initiative, make decisions, and drive impact.
"If you see something broken, fix it."
Radical Transparency
We share context liberally. Weekly all-hands, open financials, and direct feedback. Information asymmetry slows us down.
"Default to public, not private."
Ship Fast, Learn Faster
We bias toward action. Perfect is the enemy of shipped. Get it in front of users and iterate based on real feedback.
"Move fast and build things."
Disagree and Commit
Healthy debate leads to better decisions. Once we decide, we commit fully. No politics, no undermining.
"Strong opinions, loosely held."
