Kate Sullivan, 26, is the founder of The Sage Vintage, a handmade jewelry company that creates pieces using vintage charms and chains. The company, which brought in over $500,000 in revenue in 2024, began as a side hustle after Sullivan dropped out of college.

The chunky charm necklaces have been worn by SZA and Gigi Hadid, and are sold on Anthropologie’s website.
