Why we exist: On a mission to transform public procurement with AI
Do you want to gain invaluable experience at a cutting-edge tech startup while improving the inner workings of society? Then you’ve come to the right place.

We want to help ensure taxpayers get better value for their money. It’s a bold mission and a tough challenge, which is why we're seeking top talent to join our skilled team and help us make a real difference.
