A pioneer in the online consignment space, Julie Wainwright’s luxury resale platform The RealReal has emerged as one of the most influential fashion startups.

Over nearly a decade in business, the company has earned a cult following that browse the marketplace daily for deals on highly coveted apparel and accessories by brands like J Brand, Frame and Paige, which are authenticated in-house.

After helming tech standouts like Reel.com and Pets.com earlier in her career, Wainwright used her e-commerce acumen to bring the world of consignment—once dominated by brick-and-mortar boutiques—to the online masses. The RealReal has helped democratize the world of luxury, making premium goods more attainable.

It has also promoted sustainability through resale, keeping clothing, shoes, accessories and denim in circulation longer.

With roughly 1,800 gallons of water used, on average, in the production of one pair of jeans, The RealReal estimates that to date, denim consignments on its platform have saved 89 million liters of water and counting.
