Story and founders
The name ‘Belledonne′ originated from the name of a mountain range in the northern French Alps, near the city of Grenoble. Grenoble is sometimes referred to as the ‘French Silicon Valley′ due to the presence of many highly qualified engineers and a wide range of companies of different sizes working in the domains of electronics, nano-technologies and software services.
Belledonne Communications was founded in 2010 by Simon Morlat, the original author of Linphone, and Jehan Monnier, who worked for nine and ten years, respectively, in the telecom division of Hewlett Packard.
