Corporate culture

“We want to inspire people with our values”

Family tradition

SIGA was founded in 1966 by Paul and Trudy Sieber-Gadient. Their sons Reto and Marco Sieber have been focusing on globalising SIGA since 1990. In the third generation, their five children want to further develop the family business.

Team management

Since 2014, operational management has been in the hands of a team of six specialists led by CEO Patrick Stalder (right).


The 500-strong SIGA team worldwide together with several thousand craftsman customers are passionate about realising the SIGA vision. 

Develop talents

Our young talent is the key to global growth. 90% of our executives come from within our own ranks.

Unique products

Our research and development team “camps out” on the building site until we have understood everything we need to know. This is how we develop unique products. We build the system for production ourselves.

Continuous improvement

Our employees are the best business consultants. For 9 days, all work to the company standards during which time staff identify two improvements. On the 10th working day, everything comes to a halt to implement the improvements.

Mistakes are treasures

We learn from mistakes. If someone at SIGA makes a mistake, they make it known to everyone. There will be applause instead of blame. Because the recognition of errors saves the company later from more cost-intensive corrections.

Latest technologies

We are curious. We test and use the latest technologies, such as robotics, driverless transport systems, 3D printing, Business Intelligence, Internet of Things, Virtual Reality, Augmented Reality, Artificial Intelligence, etc.
