ISO, LF & WTB: how neighbors post “wanted” in the South Bay

One place for demand-led asks — whether you write ISO, LF (looking for), or WTB (want to buy). Find what you're looking for. The reverse marketplace where your ISO comes to you.

Same neighborhood energy: ISO, LF, or WTB—clear asks help the right people notice you faster.

Same intent, different slang

On ISO App, an ISO is simply a wanted post: you set the item, condition, budget, and optional hashtags so neighbors can respond. People also say LF(“looking for”) or WTB(“want to buy”) on forums and marketplaces — we welcome that language in titles and descriptions. The product is built around the reverse marketplace idea: your ask leads, supply follows.

Neighbor gifts & free asks (new on Browse)

We recently made neighbor givingeasier without a separate “charity” silo: optional hashtags #buynothing, #donation, #gift, and #freemark posts where you're open to gifts, hand-me-downs, or Buy Nothing–style handoffs. They live in the same public feed as every other ISO so dignity stays in the main experience. On Browse, use the Neighbor gifts pill to filter those asks — built for neighbors who love to give.

High-intent categories neighbors search for

Across social and local marketplaces, collectibles and trading cards (including Pokémonand related TCGs) consistently rank among the loudest “wanted” categories — people hunt specific sets, grades, and characters. ISO App is a natural fit: post the exact card or product you want, your budget, and condition, and let nearby collectors reply.

The same pattern works for family and kids (strollers, car seats, bikes), students and renters (desks, chairs, mini-fridges), furniture, electronics, and everyday free or low-cost asks. Hashtags like #kids, #furniture, #electronics help the right neighbors find you faster.

South Bay beta

ISO App is in private betafocused on the South Bay. Browse without an account; sign up to post an ISO, save listings, and message neighbors. We're intentionally small so quality and safety stay ahead of raw scale.
