Dan Leahy
Dan Leahy is the co-founder and CEO of MakerSights, a San Francisco consumer-insights platform that helps apparel, footwear, and accessories brands decide what to make before they make it. His pitch is blunt: the fashion industry still builds product the way it did in the 1980s, guessing at what shoppers want and burning through unsold inventory in the process. MakerSights collects consumer feedback at scale and ties it to real sales data so brands like Ralph Lauren, New Balance, Everlane, and Madewell can produce less waste and more of what people actually buy. Before MakerSights, Leahy founded Savored, a restaurant yield-management startup acquired by Groupon, and cut his teeth in finance at Silver Lake and Brown Brothers Harriman. A Maine kid who once mailed handwritten letters to NBA stars begging for autographs, he built a career on the same stubborn premise: ask enough people for what you want, and enough of them say yes.
Yidi Campbell
Yidi Campbell is the founder and CEO of Indyx, a San Francisco connected-wardrobe platform that lets people catalog, style, and resell the clothes they already own. A Georgetown business graduate, she moved from investment banking at Credit Suisse to corporate development at Gap Inc. and strategy at Athleta before launching Indyx in 2021 to fight fashion overconsumption from the closet outward.
Hana Kajimura
Hana Kajimura is the CEO of Trellis Group, the climate media-and-events company behind GreenBiz, Circularity and Trellis Impact. Before running the room, she built it: as Allbirds' first full-time sustainability hire she stamped a carbon footprint on every shoe, open-sourced the methodology so rival brands could copy it, and authored the 'Flight Plan' to halve the company's per-product emissions. A Stanford environmental scientist who chose business over activism because companies 'move much more swiftly,' she now runs the largest gathering of sustainability professionals in North America.
Emily Gittins
Emily Gittins is the Co-founder and CEO of Archive, a B2B SaaS platform that powers branded resale programs for 50+ global fashion companies including The North Face, New Balance, and Oscar de la Renta. A Cambridge mathematics graduate turned Stanford MBA, Gittins built Archive after stints at BCG, Google X, and the Global Fashion Agenda, channeling her technical background and sustainability conviction into a company that has raised $76.9M - including a $30M Series B in February 2025 - and been named one of Fast Company's Most Innovative Companies of 2024.
