About us

Our founder, Thomas Issler

Self-taught in fluid mechanics, our founder Thomas Issler started working on two-phase technology in 2013 to develop a water-saving device.

In 2017, the Paris Fire Brigade contacted him to work on adapting the Zelup technology to fire hoses. Since then, he has filed several patents. Always looking for new innovations, Thomas is working on a number of projects to improve firefighter safety and save one of our planet’s vital resources: water.
