Our Operating Principles:

Extreme Ownership

We take full responsibility for our work outcomes and team success. No excuses no blame-shifting if something needs fixing we own it and make it better. This means stepping up even when its not your job. If a ball is dropped we pick it up. If a customer is unhappy we fix it. If a process is broken we redesign it. We dont wait for someone else to solve it we lead with accountability and expect the same from those around us.

Craftsmanship

Putting care and intention into every task striving for excellence and taking deep ownership of the quality and outcome of your work. Craftsmanship means never settling for just fine. We sweat the details because details compound. Whether its a product feature an internal doc or a sales call we treat it as a reflection of our standards. We aim to deliver jaw-dropping customer experiences by being curious meticulous and proud of what we build even when nobodys watching.

We are majos
Be friendly & have fun with your coworkers. Always be genuine & honest but kind. Majo is our way of saying: be a good human. Be approachable helpful and warm. Were building something ambitious and its easier (and more fun) when we enjoy the ride together. We give feedback with kindness challenge each other with respect and celebrate wins together without ego.

Urgency with Focus
Create the highest impact in the shortest amount of time. Move fast but in the right direction. We operate with speed because time is our most limited resource. But speed without focus is chaos. We prioritize ruthlessly act decisively and stay aligned. We aim for high leverage: the biggest results from the simplest smartest actions. Were running a high-speed marathon not a sprint with no strategy.

Talent Density and Meritocracy
Hire only people who can raise the average; exceptional performance is the passing grade. Ability trumps seniority. We believe the best teams are built on talent density every hire should raise the bar. We reward contribution not titles or tenure. We give ownership to those who earn it and we all hold each other to a high standard. A-players want to work with other A-players thats how we win.

First-Principles Thinking
Strip a problem to physics-level facts ignore industry dogma rebuild the solution from scratch. We dont copy-paste solutions. We go back to basics ask why things are the way they are and rebuild from the ground up if needed. This mindset pushes us to innovate challenge stale assumptions and move faster than incumbents. Its how we build what others think is impossible.
