Our Story

WATTI is a family startup from Helsinki.

Our founder Joni Gefwert has run the biggest cyclorama studio in Finland since 2016. Working on large-scale productions with creative teams on a tight schedule is full of variables and random events. The same applies to modern everyday life. Creative chaos can be a thrill at its best – but only if the technology works flawlessly.

Durability is sustainability. Watti is made to last.

To us, sustainability is not only a noble value to muse about. We’re committed to respecting our environment in everyday action. Our products are multi-purpose and sturdy. We use premium materials to make hard-wearing devices and tangle-free cables. Our packaging is zero-plastic.
