Rolling Square

Rolling Square is a Swiss tech brand that began in 2014 as an Indiegogo project by two brothers, Lorenzo and Carlo Ferraris, then 24 and 18, who made a tiny charging cable designed to snap magnetically onto a keychain. The campaign for inCharge drew more than 30,000 backers and over $500,000, and the product became a global bestseller.

The company is based in Switzerland, at an address in Chiasso, and works with Italian product designers on a catalogue that now covers keyring cables, GaN chargers, Bluetooth trackers and travel accessories. Many of its products are patented, and the brand describes its method as finding a problem first and shaping the object afterwards, under the line of the lifehackers company.
