The most important pillars of our culture are: Be transparent, honest, and objective. This is what it means to be “clinical” Empathize with customers, partners, and each other Learn from mistakes and share the knowledge The way feedback is delivered to one another matters as much as the feedback itself Good work-life balance is the key to sustained productivity The measure of a team member’s effectiveness is how well the rest of the team operates in their unexpected absence No such thing as a million dollar idea, only million dollar execution Out-innovate our previous selves Check out our (work-in-progress) longform culture document.
