# Sharelum > Sharelum is a peer-to-peer review exchange. Members hand their products to real people, who use them and write what they honestly found; a moderator checks every review before it counts. Most members are both sellers and testers. It is open on Amazon (all products) and as Sharelum Books, a hub for authors and readers; other marketplaces are coming soon. ## How it works 1. A seller posts a request (one review or a campaign of up to fifty) and pays in points upfront, so every slot is funded. 2. A tester claims a request they would genuinely use and is paid in points when they claim. 3. The tester uses the product, then leaves a 1–5 rating and an honest review on the marketplace. Digital products need no delivery (instant access, review within the 24–72 hours the seller picks); physical products must arrive and be used first, so testers get 30 days. 4. A moderator verifies the review, sends it back for changes, or rejects it. Rejected or abandoned tests return the points and the slot. ## Founding 100 - 100 founding spots, 12 months free with no card, 1,600 starter points, then $5 a month for life. - Join the waitlist; invites go out in batches.
