Our values tell the story of Tyk – here’s how:

  • It’s ok to screw up!

We’ve found that it’s often the ‘stupid’ or unexpected ideas that turn out to be the successful ones – so try it, at least we can say we have!

  • The only stupid idea, is the untested one!

It’s in our DNA – starting a business with founders 12 hours apart, giving our gateway away for free – sure, we did that, and we’d do it again!

  • Trust starts with you – make it count!

Trust is a two-way street – instill it from day one!

  • Assume best intent!

We have each other’s back – we’re all on the same team. Think before you speak or act.

  • Make things, better!

Always try to leave things better than when you found them – change is constant, inevitable and embraced! Be that change we want to see.
