Why Kitt?

The world of work has shifted forever. As people everywhere prioritise purpose over their paychecks, company culture has been thrown into the spotlight. But the problem is, too many companies are showing up to work in bland, cookie-cutter offices. We’re leading this change.

Real company culture can only be built in-person, in the real world – and for it to be authentic it needs its very own, personalised space. That’s why we create offices as unique as the brands and the people who work there. We’re long-term culture partners to our clients long after they've signed the lease and chosen the paint colours.

We’re disrupting an industry that has long needed a shake up, and with our sights set on helping every brand find their dream home, the future of office space and culture is in very good hands.
