Unlimited, flexible PTO Flexible work schedule Company laptop and allowance for any necessary home equipment Two company-paid off-sites per year 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.
