About us

Sy&Se SA specializes in assembling glasses with metals and ceramics – for all kinds of domains and applications.

Our History

Sy&Se (pronounced [saɪ] [ænd] [siː]) was founded in 2017 as a spin-off company from Haute-Ecole Arc Ingénierie (HE-Arc, which belongs to the HES-SO, the Universities of Applied Sciences of Western Switzerland), and specializes in assembling glasses with metals and ceramics.

The company is an outcome of an Innosuisse (formerly CTI) project between the Haute-Ecole Arc (HE-Arc) and a leading high-end watchmaking company. This collaborative project was focussing on assembly processes, an essential step in most industrial manufacturing processes as it contributes to obtaining high-performance and high-quality end products. ICB, the so called Impulse Current Bonding process based on a major scientific discovery, came out of this development and sparked the creation of Sy&Se.

In 2020, the company’s legal form evolved from an sàrl to an SA with its own Board of Directors. To support its growth, the company moved early 2023 from La Chaux-de-Fonds to Saint-Blaise, near Neuchâtel, into more spacious premises tailored to its industrial activities.
