What Seller Assistant does

Seller Assistant is an all-in-one Amazon seller software platform built for wholesale and online arbitrage merchants, operated by the US LLC Linen Art and founded in 2019. The product combines a browser extension (available on Chrome, Firefox, and Microsoft Edge), a web application, and a public API into a single sourcing workflow organized into four stages — Discover, Analyze, Source, and List — with corresponding tools such as the Brand Analyzer, Seller Spy, Price List Analyzer, Bulk Restriction Checker (handling up to 20,000 ASINs per pass), AI Supplier Finder, Purchase Orders, Suppliers, Warehouses, Lister, FBA Shipments, and SKUs. A standalone IP-Alert extension provides automated intellectual property complaint monitoring, and a complementary VPN extension supports privacy during competitive research. The platform integrates natively with Amazon Seller Central, Zapier, Make, n8n, Google Sheets, Airtable, and third-party prep centers, and the company holds verified Amazon Software Partner status.

The technology stack is browser-first SaaS with workflow-automation hooks, designed to eliminate tab switching between Amazon, Keepa, and supplier sites by overlaying margin, Buy Box, IP risk, and competitor data directly on Amazon and supplier pages. Proprietary IP-complaint data collection and 1M+ monthly ASIN analyses feed risk and product intelligence features that the company describes as differentiated versus competing Amazon seller tools.

The business model is primarily subscription SaaS, accessed via a 14-day free trial with a self-serve product-led growth motion, supplemented by free tools (ASIN/IP-Alert/UPC/EAN converters) for top-of-funnel acquisition and an affiliate program for partner referrals. A sales-assisted motion via a /demo route targets agencies and enterprise accounts, and sub-account provisioning supports virtual-assistant delegation. The customer base is a long tail of SMB Amazon sellers doing $10K–$500K+/month in revenue, plus a growing Amazon seller agency segment; the company is founder-led, bootstrapped, privately held, and headquartered in San Diego, California.
