- Medical, dental, and vision insurance - Coverage worldwide.
- Paid time off - Love the slopes or the sea? Enjoy them with 25 vacation days, plus an extra loyalty day each year, capped at 5 years (30 days total), on top of your local public holidays.

- Paid sick leave - Feeling ill? Take time off to fully recover without having to worry about your finances.
- Parental leave - Paid 16 weeks for birthing parents, 8 weeks for non-birthing parents. If your country gives more, that’s your baseline. If it gives less, we top it up. Take your leave all at once or split it across the first year for maximum flexibility. After paid leave, your local statutory rules apply.
- Annual fluffle building - We're remote, but not distant! Once a year, we meet in a sunny location where virtual high-fives turn into real ones.
