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.
