The bottom line

We are 60+ passionate, diverse, fun-loving and data-driven people. We are humble, embrace differences, and have a strict “no assholes” policy.

Haven't fallen for us yet?

  • Cool stuff at the office!

    Oh yeah that's right, in Sweden we've built a nice (but small) gym that's free to use for all employees! After the gym, please take a rest in our Zen Room. There's also a ping-pong table and a dart board in UK. There's a lot of cool stuff happening at the Karma offices - like yoga every Wednesday!

  • Early bird or night owl?

    We got you covered! Come early and join our weekly breakfast and/or stay late to play video games and have some snacks!

  • Celebration time!

    Karmazing After Work or a Swedish fika? We always find creative ways to celebrate ourselves and our wins.
