OUR VALUES

• Kindness Matters. We show kindness and respect to all users, customers, and team members in every interaction (internal and external). Being kind compounds and strengthens our relationships.

• Craftsmanship Excellence. We deeply care about the quality of everything we create. Every contribution, regardless of size, must meet our high standards for excellence.

• Radical Transparency. We communicate openly and honestly with each other. Respectful candor is valued over comfortable silence, as we can't afford to miss insights due to fear of speaking up.

• Bias for Action. We believe action produces information. At no more than 20% completion of a project we must have a working prototype to test and iterate on.

• Speed with Purpose. We move with urgency and focus. Slow and expensive usually go together. Good, fast, and cheap outcomes are perfectly achievable through disciplined execution.

• Professional Integrity. We never speak negatively about competitors, partners, vendors, or others. Such behavior reflects insecurity and provides no value.

• Creative Problem-Solving. We value innovative thinking that challenges conventions. The best solution aligns with the task at hand, not necessarily with how things have always been done.

• Team Over Ego. We share both successes and failures collectively. No individual's ego should surpass our commitment to the product and its impact.

• Results Over Hierarchy. We do not care about titles in this company. No politics, no hierarchy. All we care about is winning together.
