Vendoo
Vendoo is a crosslisting and inventory-management platform for online resellers. From one dashboard, sellers post a single item to 10+ marketplaces - eBay, Poshmark, Etsy, Mercari, Depop, Facebook Marketplace, Grailed, Vinted and more - and the software handles the repetitive parts: detecting a sale and auto-delisting the item everywhere else, tracking inventory, sending offers, and calculating fees and profit. Founded in 2017 and part of Y Combinator's Winter 2022 batch, Vendoo says it serves more than 81,000 resellers who have created over 26 million listings on the platform.
Flyp
Flyp is a San Francisco software company that builds affordable, all-in-one tools for online resellers. Its Crosslister moves a single listing across Poshmark, eBay, Mercari, Depop, Etsy and Facebook Marketplace, while its Poshmark bot automates closet sharing, offers to likers, follow/unfollow and CAPTCHA solving. Founded in 2018 by James Kawas and Dani Arnaout, Flyp positions itself as the enterprise-grade toolkit for the roughly hundreds of thousands of 'power resellers' who move used goods for a living - at $9/month after a long free trial, undercutting rivals that charge $100+.

It builds and operates customized secondhand storefronts for fashion and lifestyle brands - including The North Face, New Balance, Oscar de la Renta and Dr. Martens - so they can keep products in circulation, capture a new revenue stream, and meet customers who increasingly refuse to buy new.
