Crolles is known to host the biggest semiconducting fab of France (4,000 people, for a total investment of 3 billions euros). First founded by STMicroelectronics in the 1980s, the recent development (Crolles 2, 2003) results from a joint-venture with Philips (today NXP semiconductors) and Motorola.

Crolles is also the birthplace of Petzl, the leading company of safety equipment for mountaineering, caving and vertical safety in civil engineering, which still has its headquarters there.
