Lorenzo Filiberto Ferraris

Co-founder at Rolling Square

12 years designing compact tech accessories · 4× CES Innovation Awards · 3× Red Dot Design Awards · 2.2M+ products shipped to 122+ countries

Lorenzo co-founded Rolling Square in 2014 in Chiasso, Switzerland, the company that invented the keyring charging cable category. For over a decade he has designed and tested compact everyday-carry tech: the inCharge® keyring cables, the TAU® keychain power banks, the AirCard® and AirNotch® dual-network trackers, and the Supertiny GaN chargers.

His design philosophy is the one Rolling Square is built on: shrink the kit. The best gear is the gear you cannot forget, so every product he works on has one fixed home, on your keys, in your wallet, or on your bag, and replaces more than one thing you used to carry.

The work he has been part of has earned Rolling Square 4 CES Innovation Awards (2020, 2021, 2023, 2024), 3 Red Dot Design Awards (2021-2023) and 10+ patents, with 2.2M+ products delivered to 122+ countries and 164,000+ crowdfunding backers across 10 campaigns.
