Executive Assistant, Ghost

With retailers wasting around $500 billion a year on excess inventory, demand for solutions like Ghost's is sky-high. The company has also made good on this demand, emerging from stealth mode in 2022 and about $38 million in funding to date. Ghost, which functions in much the same way as eBay, has benefited hugely from its founder's prior experience in the apparel industry.

Ghost's clear focus on sustainability and discretion has broad market appeal, especially for large-scale retailers looking to reduce waste and improve their public image. If Ghost can continue to attract such clients, it could scale at an impressive pace in the coming years.
