• 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.
