Sigfox is the world's leading provider of connectivity for the Internet of Things (IoT) that has built a global network to connect billions of devices to the Internet while consuming as little energy as possible, as simply as possible.

Sigfox's unique approach to device-to-cloud communications addresses the three greatest barriers to global IoT adoption: cost, energy consumption, and global scalability.

Sigfox was founded in 2009 by Ludovic Le Moan and Christophe Fourtet. The company is headquartered in Labège near Toulouse, France’s “IoT Valley” with additional offices in Paris, Madrid, Munich, Boston, San Francisco, Dubai and Singapore.

Sigfox empowers companies to create new innovations on the IoT with millions of objects connected and a rapidly growing partner ecosystem.

Sigfox has partnered with a number of firms in the LPWAN industry such as Texas Instruments, Silicon Labs and ON Semiconductor. The ISM radio bands support limited bidirectional communication.

Sigfox employs the differential binary phase-shift keying (DBPSK) and the Gaussian frequency shift keying (GFSK) that enables communication using the Industrial, Scientific and Medical ISM radio band which uses 868MHz in Europe and 902MHz in the US. It utilizes a wide-reaching signal that passes freely through solid objects, called "Ultra Narrowband" and requires little energy, being termed "Low-power Wide-area network (LPWAN)".

Sigfox's investors include Khazanah Nasional, Salesforce Ventures, Bpifrance, & Total Energy Ventures among others.
