Haley Lieberman
Director, Network & Industry, North America
Ellen MacArthur Foundation
Haley works with the Ellen MacArthur Foundation’s corporate network partners to align strategy and steward key relationships that accelerate circular economy implementation across the Foundation’s three mission areas: critical minerals, fashion and textiles, and plastics and packaging.
For more than a decade, Haley built and scaled technology-driven circular solutions. She began in the fashion and textile space, founding a venture-backed resale marketplace that was later acquired, and launching additional fashion recommerce ventures. She has also supported climate technology startups across renewable energy, carbon capture and utilization and advanced materials.
Haley served as Director of Marketing and Community at ClimateHaven, the Yale-backed climate tech incubator, where she led partnerships, marketing, programming and the cross-sector network. She holds advisory roles in climate-tech startups, with Moving the Needle, an initiative of Yale’s Center for Business and the Environment, and with Sustainable Westport.
