Momox

What Momox does

Momox SE is a Berlin-headquartered European recommerce company that buys used books, media articles (CDs, DVDs, Blu-rays, games), and clothing from private individuals at fixed, algorithm-generated prices and resells them through its own e-commerce storefronts (medimops for books and media, momox fashion for apparel) and via Amazon and eBay, where it is the world's largest retailer of used goods and third-largest, respectively. The operating model is built on a proprietary pricing algorithm refined over 20 years and more than 400 million transactions, combined with systematic quality grading, brand authentication for fashion, and dedicated logistics centers in Leipzig (books and media, over 100,000 m²) and Szczecin, Poland (fashion, photography, authentication).

The technology stack centers on a mobile scanning app that delivers instant buyback quotes, an integrated recommerce platform linking intake, grading, and resale, and computer-vision-supported photography workflows for fashion listings. Momox processes up to 149,000 items per day and serves more than 50 million customers across markets including Germany, Poland, France, Italy, Spain, and Austria, with an eight-person management team overseeing Books & Media, Fashion, technology, growth, and operations.

Revenue is generated from the margin between buyback price and resale price across millions of long-tail SKUs, distributed across owned storefronts and third-party marketplaces, supported by approximately 1,700 employees and a 114,000 m² logistics footprint. The company reported €393.5 million in annual turnover for 2025 and emphasizes profitable operation as a core value, with no disclosed private equity or venture capital majority ownership.

Core offering

momox SE buys used books, media articles (CDs, DVDs, Blu-rays, games), and clothing from private individuals at fixed prices. After systematic quality control and, for fashion, brand authenticity verification, the items are resold through the company's own e-commerce storefronts (medimops for books and media, momox fashion for clothing) and through major third-party marketplaces (Amazon and eBay). A proprietary mobile app allows sellers to scan items and receive instant fixed-price offers.

Product overview

Momox SE operates a unified recommerce platform with three consumer-facing brands: momox (the selling/buying platform for used books, media, and clothing), medimops (the retail channel for second-hand books and media), and momox fashion (the fashion retail channel). The ecosystem is supported by a proprietary mobile app for instant valuations, two large-scale logistics operations in Leipzig (books/media) and Szczecin (fashion with photography studio), and quality control processes that assess, categorize, and authenticate items before resale. The company is the world's largest retailer of used goods on Amazon and third on eBay.

Direct peers

• WeBuyBooks: UK app-based platform offering instant fixed-price buyback for used books and media — directly analogous to momox's mobile-app scanning and instant pricing experience for sellers.
• Music Magpie: UK-based recommerce platform that buys and resells used CDs, DVDs, games, books, and tech devices from consumers — a near-identical business model to momox's books and media division, but serving the UK market.
• World of Books: UK's largest seller of second-hand books, buying used titles from consumers and reselling through its own site and marketplaces including Amazon — directly comparable to momox's medimops business.
• Rebuy: German recommerce company that purchases used books, media, and electronics from consumers for online resale — overlaps with momox on geography (Germany), supply model (consumer buyback), and core product categories.
• Ziffit: UK-based media buyback service that purchases used books, CDs, DVDs, and games from consumers for resale — competes with momox's media buyback model in an adjacent European geography.
• Vinted: Lithuanian-headquartered peer-to-peer second-hand fashion marketplace operating across Europe; directly competes with momox fashion for both buyers and sellers of used clothing.
• Sellpy: H&M-owned managed-model second-hand fashion resale service — competes with momox fashion through a similar managed-supply, quality-controlled resale approach rather than peer-to-peer listings.

Broad incumbents

• ThredUp: US-listed managed-model second-hand fashion platform operating at greater scale than momox fashion; competes in the same category though primarily in North America.
• Amazon: Amazon's used and refurbished goods marketplace is both momox's largest external distribution channel and a broader competitor, as Amazon itself retails used books and media alongside momox's listings.
• eBay: Global online marketplace for used goods and momox's second-largest third-party channel; functions as both a key distribution partner and an indirect competitor for second-hand buyers and sellers.
