About Closo — Sell on Every Marketplace

AI Agents for Resale — Source, Price, List & Liquidate Automatically Smarter decisions. Less work. More profit — AI that runs your resale business. Free Tools (Onboard & Operate) - List & Crosslist instantly: Use AI autofill to post on eBay, Poshmark, Mercari, Depop, Shopify—no manual copy-paste. - Share & Send Offers Smartly: Agents schedule shares at peak times and send offers based on demand signals. - Bulk Relist / Delist / Manage: Control status toggles or restock actions in bulk from one dashboard. AI Agents (Your Autopilot Team) - Sourcing Agent: Spots trending, high-demand items before they spike and auto-lists them in your store. - Crosslisting Agent: Posts your inventory across marketplaces with channel-optimized listings. - Promotion Agent: Shares and offers your listings at the highest-conversion windows. - Optimization Agent: Continuously runs dynamic pricing models, keyword tweaks, and automated markdowns to capture demand. - Liquidation Agent: Detects slow-moving stock, applies markdown cadence, and routes inventory to secondary channels to recover capital. - Trend Spotting Agent: Monitors live markets to give you early signals on what to stock. Liquidate & Recover Capital - Automated Markdowns & Clearance Pricing: Set rules (percentage, time-based, floors) and the system will safely lower prices gradually without you needing to monitor each SKU. - Channel-based Liquidation: For underperforming items, Closo’s agents select which secondary marketplace or resale network is most likely to move inventory—and auto-list there. - Maximize ROI on Dead Stock: Minimize waste and loss; Closo helps you salvage margins from aging inventory. Source, Stay Ahead - Zero-Risk Sourcing: Pick from curated returns, overstock, brand excess—only pay when item sells. - Supply Meets Demand: The platform matches what is trending with what you can sell, keeping your store fresh and aligned. Why Closo Works - AI-first Automation: Instead of doing repetitive tasks, let agents act—while you override or approve as needed. - Free to Start: Core tools come without fees — begin listing, sharing, analyzing at no cost. - From Individual Sellers to SMBs: Whether you're managing one SKU or thousands, Closo scales with your workflow. - Data-Driven Profit Focus: Every decision (price move, markdown, liquidation) is laser-guided by market data and ROI thinking. Our vision: At Closo, we believe the future of reselling isn’t about working harder — it’s about working smarter with AI. While most crosslisters like Vendoo, List Perfectly, or PrimeLister help you post faster, Closo goes further — it thinks for you. Our mission is to give every seller and SMB the same power as a full-scale e-commerce team: sourcing profitable inventory, pricing it dynamically, and liquidating unsold stock automatically. We’re building an ecosystem of AI Agents that understand real market behavior — analyzing sell-through data, competition, and seasonality — and turning those insights into actions: crosslisting, markdowns, repricing, sourcing and liquidation unsold inventory. Whether you sell on eBay, Poshmark, or Shopify, Closo helps you manage your entire resale cycle — from first listing to final sale — in one place. We’re building the AI resale infrastructure of the future — a platform that learns from the market, acts for you, and helps sellers thrive in the new era of intelligent commerce.
