Team
Cohesion and trust
Our culture is rooted in transparency, so we are open with each other - with a strong bond as a result.
Who we are
- We are small and we like it that way.
- We choose to do one thing and do it right.
- We apply Occam’s Razor in all our solutions.
- We do something because it makes sense.
- We treat others like we want them to treat us.
If all else fails, we flip a coin.
