The SUMM Cultural Manifesto

This is our own SUMM Cultural Manifesto. We don't just create it for our clients, but also - very much - for ourselves. Building strong cultures starts with how you shape your own.

Who we are, how we work and what we stand for: all laid out in this manifesto.

At SUMM, it’s all about culture. Not as a buzzword, but as the tangible force that drives how people collaborate, grow, and achieve.

In this manifesto, you’ll discover who we are, where we started, and what fuels us. We share our mission, our Cultural DNA, the rituals that give us rhythm, and the principles that guide us. No grand theories or jargon - just how we shape culture ourselves, every single day.

This manifesto isn’t just for clients; it’s for us, too. As a compass. As a touchstone. Because you can’t build culture for others unless you live it yourself, first.
