What OneShop does
OneShop is a mobile-first, subscription-based cross-listing platform built for individual online resellers who sell secondhand goods across multiple marketplaces simultaneously. The platform allows users to draft a listing once and publish it to 12+ supported marketplaces, including Poshmark, Mercari, Depop, eBay, Etsy, Grailed, Kidizen, Facebook Marketplace, Tradesy, Vinted, Vestiaire Collective, and The RealReal. Automated bots handle repetitive seller workflows such as relisting, bumping, and sharing, and items are automatically delisted from other marketplaces when sold, preventing double-selling. Smart autofill and description templates reduce per-listing time, and a unified sales dashboard provides goal-setting and peer benchmarking against other OneShop users.
The product is delivered via a mobile app and web interface using a self-serve, product-led growth model — users sign up with a phone number and complete setup in under three minutes, with a 7-day free trial preceding conversion. OneShop monetizes through a single subscription tier, OneShop Premium, priced at $45 per month, providing full access to all cross-listing, automation, and analytics features. The company was founded in 2021, is headquartered in New York with support operations in San Francisco, operates as Inventory Systems Inc., and is a Y Combinator Summer 2021 graduate that has raised undisclosed funding led by General Catalyst. Distribution is entirely direct-to-consumer and global, with no channel partners, and customer acquisition is driven by an SEO-optimized content marketing engine spanning 100+ blog articles and a multi-platform social media presence.

OneShop competitors and assessment
Company assessmentEmerging players
- ResellMate: Emerging cross-listing and automation tool targeting online resellers with partial overlap on supported marketplaces and automation features. Smaller-scale entrant compared to OneShop.
- Zibbet: Multichannel platform for handmade and vintage sellers that integrates with several marketplaces and provides listing management. Overlaps with OneShop in cross-listing mechanics for a niche of independent sellers.
Direct peers
- Flyp: Reseller tool focused on cross-listing and selling across multiple marketplaces, with comparable automation and listing management features. Targets the same individual reseller segment as OneShop.
- List Perfectly: Direct cross-listing competitor for online resellers across Poshmark, Mercari, eBay, and other marketplaces. List Perfectly is named on OneShop's own website as a competing trademark and offers a very similar cross-listing and automation feature set.
- Vendoo: Direct cross-listing competitor for resellers, also named on OneShop's website as a competing trademark. Vendoo provides multi-marketplace listing, automation, and analytics tools aimed at the same individual reseller customer.
- Crosslist: Cross-listing tool for resellers that lists inventory to multiple marketplaces from a single interface. Competes head-to-head with OneShop on cross-listing speed, automation, and marketplace coverage for individual sellers.
Broad incumbents
- Sellbrite: Established multichannel listing and inventory platform focused more on SMB and brand sellers across major marketplaces like Amazon, eBay, and Shopify. Overlaps with OneShop on cross-listing but serves a different, more business-oriented segment.
- LitCommerce: Multichannel commerce platform that lists and syncs inventory across e-commerce channels. Shares the cross-listing and inventory-sync DNA with OneShop but targets broader retail and brand use cases beyond secondhand resellers.
- ChannelEngine: Enterprise multichannel commerce and marketplace integration platform. Comparable in marketplace-connectivity mechanics but aimed at larger brands and retailers rather than individual resellers.
- SelluSeller: Multichannel listing and order management tool for sellers across multiple marketplaces. Adjacent to OneShop in cross-listing capability, but positioned for broader e-commerce sellers.
