In January of 2018, Hadar Kaly developed the flu and began binge watching Great British Bake Off. They decided to try out baking various types of breads and discovered that they loved it. They had worked at Bluestockings Bookstore since 2014, and upon returning to work, pitched the idea of selling their baked goods in the cafe at the bookstore, which had not had a consistent vendor since 2015. On January 31st, 2018, Tivoni Treats officially opened at Bluestockings Bookstore in the Lower East Side of Manhattan.
In August of 2019, Hadar graduated from Chef's Training Program at Natural Gourmet Institute in Manhattan, a plant-based and health supportive culinary school. The same month, they began as a line cook at Avant Garden in the East Village.
