What Deja Vu does

多抓鱼 (Deja Vu / Duozhuayu) is a Beijing-headquartered for-profit company founded in 2017 that operates a C2B2C circular-economy marketplace for second-hand goods in China. The core product is an online platform at duozhuayu.com, accessible via web and WeChat, where consumers can sell pre-owned items — primarily books, and increasingly clothing and electronics (smartphones, e-readers, tablets, gaming consoles) — by scanning barcodes for instant pricing or listing items manually. The platform then resells these items to other users after curation, cleaning, and condition grading, capturing a transaction commission on each sale.

The product surface is layered: the second-hand book marketplace (图书交易平台) remains the flagship, supplemented by dedicated clothing (服饰交易) and electronics (电子产品交易) verticals, plus a proprietary DEJAVU-branded original-merchandise line of upcycled apparel and accessories. Distribution is omnichannel — the website and WeChat official account form the digital backbone, while five physical retail locations in Shanghai (Hongqiao Tiandi B1, Anfu Road 300), Beijing (Langyuan Vintage 18c), Shenzhen (Wanxiang City), and a Yangzhou pop-up (Guangling Road 276) provide offline browsing and pickup. Discovery and engagement are driven by editorial curation — book reviews ("别人的鱼"), the "鲜鱼榜" (Fresh Fish List), and user-generated ratings — distributed across categories spanning literature, social science, children's books, and over 60 other classifications.

The revenue model is a take-rate on successful transactions; items range from approximately ¥3.40 for common used books to ¥420.50 for rare editions, with no subscription or membership fees disclosed. The company has raised approximately $10.67M across three early-stage rounds (2017-01 K2VC, 2017-12 K2VC + Matrix Partners China + Next Capital, 2018-05 Tencent), and its platform has facilitated a cumulative circulation of 54,946,306 second-hand items. Headcount is reported at 101-250 employees, with the company legally registered in Beijing under primary entity "多抓鱼 (Duozhuayu)".

Regional players

• The RealReal: US-based online marketplace for authenticated luxury consignment with strong authentication and condition standards. Comparable to Duozhuayu's curated/quality-controlled resale approach with trust and authentication as a category moat.
• thredUP: US-based online resale platform focused on used clothing and accessories with circular-economy positioning. Comparable to Duozhuayu's clothing resale vertical and demonstrates scaled circular resale economics in a different geography.
• Mercari: Japan-origin C2C marketplace for second-hand goods with marketplace model similar to Deja Vu. Comparable in product breadth and self-serve listing model, though Mercari operates in Japan and the US while Deja Vu is China-only.

Direct peers

• Xianyu (闲鱼): Alibaba's dominant consumer-to-consumer second-hand marketplace in China with broad category coverage spanning books, clothing, electronics, and more. Directly competes with Deja Vu across virtually all verticals but with vastly greater scale and platform-embedded discovery.
• Zhuanzhuan (转转): Tencent-backed second-hand marketplace with strong vertical focus on used electronics and general second-hand goods. Direct competitor on electronics trade-in (smartphones, tablets) and general second-hand transactions in China, sharing WeChat distribution advantages.
• Aihuishou (爱回收): China's leading used electronics trade-in and resale platform with device buyback, refurbishment, and resale capabilities. Direct competitor for Deja Vu's electronics vertical (smartphones, tablets, e-readers, gaming consoles).
• Kongfz (孔夫子旧书网): China's largest dedicated used and out-of-print book marketplace, founded in 2002 and long-established. Direct competitor in the used books space that Duozhuayu's core platform primarily addresses, though Kongfz skews more toward rare and antiquarian titles.

Broad incumbents

• JD Paipai Used (拍拍二手): JD.com's used and refurbished goods platform leveraging JD's logistics, authentication, and consumer trust for second-hand commerce across electronics and general categories. Broad incumbent competing across Deja Vu's verticals with established retail infrastructure.
