Thrifter

Thrifter is a swipe-based secondhand fashion marketplace for iPhone built by Sachin Muralidhar and operated through A Fish N Sea LLC.¹ Buyers swipe right on items they want and left to skip; sellers can send binding offers, including on multi-item bundles, and the marketing site advertises "no buyer fees" as a headline feature.² Thrifter is part of the Canopy Spring 2026 cohort at Founders, Inc.

Origins

Muralidhar is based in the San Francisco Bay Area and previously shipped buzz, a location-based group-chat app published under the same Apple developer account.⁵ His LinkedIn profile lists the University of Virginia as his education.⁴ The Thrifter App Store listing first drew user reviews on January 9, 2025, when the app was running an earlier interface centered on curated daily looks and image-based thrift search.¹

The pitch on the App Store frames the product as a generational reset on resale software: "most resale apps were built for your grandpa — thrifter is built for us."¹ In an October 16, 2025 LinkedIn post, Muralidhar described the prior nine months as "pivoting, iterating, and navigating the complexities of the secondhand market" before he launched the "Tinder for Thrifting" interface "a couple of weeks ago" and crossed 100,000 swipes in the following three days.³

Product

The core interaction is a vertical card stack: buyers swipe right to like an item and left to skip, building a personalized feed that the algorithm weights toward active sellers.¹ Sellers can send binding offers, including binding offers on bundles of multiple items.¹ Tapping an image opens additional photos without leaving the feed, keeping the swipe loop intact.¹

The fee model is the second pitch on the marketing site, alongside the swipe UI: the homepage lists "no buyer fees" and "binding offers" as the two headline features.² A separate fee-breakdown page documents the seller-side fee and shipping structure.⁶

The app requires iOS 15.6 or later, is 151.8 MB, and is rated 13+ for messaging and user-generated content.¹ As of April 17, 2026 it has a 4.9 average across 345 ratings on the U.S. App Store.¹ Apple Wallet is supported.¹

Founder and operations

The legal entity behind Thrifter is A Fish N Sea LLC, copyrighted 2025 on the App Store listing.¹ The developer record on Apple's store remains under Sachin Muralidhar's individual name rather than the LLC.⁵ One reviewer, ahan.mp4, wrote on July 10, 2025 that "the founder has even sent me personal messages for feedback and how to improve his app," and reviewer Abbas M O reported in April 2026 that the developer reached out and issued a full refund after a seller failed to ship.¹

Release notes show a near-daily ship cadence. Between March 16 and April 9, 2026, Thrifter pushed at least eleven point releases — bug fixes, a new make-offer UI, a bundle banner, conversation pinning, and an inbox cleanup among them.¹ A March 24 release credited user @fleegles_finds for advanced seller features, and a March 28 release rebuilt the recommendation algorithm with a heavier weighting on seller activity.¹ One mid-April release note flagged that a previous day's update had "almost melted the database" under load from new signups.¹

Mission

Thrifter's stated mission, repeated across the App Store description and the homepage, is to "end fast fashion" by making resale faster than buying new.¹² Muralidhar's App Store copy argues that secondhand commerce is growing but that fast fashion is growing faster: "if resale is not easier and more efficient, we fall behind."¹
