FounderFinder Sidebar

Auto-detects Amazon brand and seller, searches Google for LinkedIn founders, scores results, caches per listing.

FounderFinder Sidebar is a Chrome extension built for Amazon agencies, brand researchers, ecommerce professionals, virtual assistants and e-commerce investors who need to quickly identify the founder, owner, or CEO behind any Amazon brand or seller store. What it does Open any Amazon product listing and FounderFinder Sidebar automatically extracts the brand name and seller name from the page. It then runs targeted Google searches in the background — using advanced boolean queries like site:linkedin.com/in "Brand Name" founder OR owner OR CEO — and scores every LinkedIn result from 0 to 100 based on how likely the person is the actual brand founder. Only high-confidence matches are shown.
