Launched Grabbit publicly today. Grabbit is a search engine for secondhand marketplaces. It lets users search Facebook Marketplace, Craigslist, OfferUp, Depop, Mercari, and more in one place, then open the original listing when they want to buy or message the seller. The biggest thing I learned while building it is that aggregation alone is not enough. Search quality, speed, alerts, and pricing context matter just as much. I also launched GrabScore, which helps users judge whether a listing looks like a strong deal, fair value, or overpriced based on similar listings, plus saved search alerts for new matching listings. Now the focus shifts from building to distribution and figuring out which part of the product is most compelling to lead with. Would love feedback from other founders on positioning: Should this be framed primarily as a search product, a deals product, or a broader secondhand shopping tool? grabbit.app
