Strategic Consultants

Madeleine Danzberger grew up in her mother's consignment store, and she has been working on what happens to clothes after someone buys them ever since. She leads product and go-to-market at Turnstyle, an early-stage platform that turns a luxury wardrobe into a managed collection that's easier to care for, repair, and resell. She likes problems that need both good technology and good relationships to solve.

Before Turnstyle, Madeleine spent three years on the sustainability team at Steve Madden. She built the strategy for the company's corporate foundation and managed its roughly $1M in annual giving, led ESG and CDP reporting, and ran circularity programs that kept more than 60,000 pounds of sample waste out of landfill. She launched a resale partnership with ThredUp across Steve Madden, Betsey Johnson, and Dolce Vita, and worked with EarthDNA and the MIT Media Lab on research into footwear circularity.

Madeleine co-founded Water Emissaries, a nonprofit where she oversaw programming and operations. She scaled its water and climate education program, which taught college students to use their majors as tools for advocacy. She is also a co-founder of The Key, the community arm of Ankh Impact Ventures, which supports early-stage female founders and fund managers. She is the youngest member of the Goodwill NYNJ board and was named a 2024 Aspen Institute Future Leader. She holds a BS in Environmental Science, with a minor in Art History, from American University, where she received the Frederick Douglass Distinguished Scholarship for her work in sustainability and social impact. Originally from Minnesota, she lives in New York.
