How ISO hunts

Post once. Sellers come to you.

Instead of hunting across a dozen tabs yourself, tell us what you're in search of and let ISO's agents do the legwork.

1. Post your request. Describe what you want: item, grade, year, condition, budget, in plain language. ISO's agents turn it into a live hunt the moment you post.
2. Sellers are notified. Only sellers whose inventory lines up with your ISO get the alert: grade, set, condition window, and price range, not just a loose keyword.
3. Responses come to you. Sellers who have what you're after respond directly inside ISO: photos, certification numbers, condition notes, and price. Everything stays on ISO so you can actually compare.
4. Compare and decide. Review responses side-by-side. Message sellers directly through ISO's on-platform chat. Ask for additional photos, negotiate price, or request alternate grades, without sharing personal contact info.
5. Close on-platform. Payment and shipping are handled through ISO, and every step is tracked on-platform so nothing gets lost between you and the seller.

Your inventory, working while you sleep.

Connect your catalog once. ISO monitors every incoming request and surfaces the ones you can actually fill.

1. Catalog matched. Upload your inventory, individually or in bulk. ISO reads each item's set, year, grade, and condition. Your catalog becomes a live hunting ground for buyer ISOs.
2. Request alert. When a buyer's ISO lines up with something you have, you get a direct notification with their budget signal and preferred grade range, so you can respond competitively.
3. Respond and close. Respond with photos and any relevant certs. If the buyer moves forward, ISO handles the conversation and transaction on-platform. No back-and-forth outside it.

What ISO considers when making a match

Finding the right seller isn't a keyword lookup. ISO weighs multiple signals to surface the right seller for each ISO, and the right ISO for each seller.

• Item details. Grade, year, set name, variant, and condition are read and normalized from both the ISO and the seller's listing.
• Budget signals. Buyers set a price range. ISO checks it against the seller's asking price before surfacing the match.
• Match quality. ISO tracks which matches lead to successful conversations and uses that signal to improve future matches over time.
• Response speed. Sellers who respond to alerts quickly are prioritized in the match queue.
