- Ask for forgiveness, not permission: We are building a category-defining company, and that requires speed, boldness, and ownership. If you see something that needs doing, do it. Don’t wait. Own it. If it goes wrong, learn fast and fix it. Celebrate initiative. Mistakes are feedback, not failure.
- Discomfort is where growth happens: Growth doesn’t come from playing it safe. It comes from stretching beyond what you already know. Embrace change, seek new challenges, push your boundaries. We reward those who are brave enough to try, fail, and learn.
- Stay hungry, ditch the ego: Spartans are ambitious - but for the mission, not for the politics. Leave your ego at the door. Titles don’t matter. Results do. Focus on what drives real outcomes, not what makes you look good. Ambition fuels progress, and humility keeps us grounded.
- Fall in love with the problem: We exist to solve real customer problems - not to push our ideas. Always start with their needs, not our assumptions. Everything else is noise.
- Challenge openly, support fully: We grow through truth, not silence. Feedback is a gift - but only when it’s shared with courage and care. Radical candour builds trust. We embrace diverse debate, but once a decision is made, we align and wholeheartedly commit.
