Industrial designer Andrea Leggitt started SaltyandSweet + OTTI in 2008, as she made mobiles to keep her mind and hands busy while undergoing cancer treatments. At that very same moment in time, Etsy was incubating and poised to completely revolutionize the handmade market. Leggitt listed one mobile on the website shortly after Etsy launched, it sold immediately, and a business was born.

Drawing from her experience as an industrial designer who grew up in a family of architects, all OTTI designs are heavily influenced by architectural design while maintaining a focus on wearability and deliberate use of lightweight materials.
