Carousell – A Mobile-First Marketplace

Founded in 2012, Carousell is a Singapore-based tech startup that provides a mobile-first platform for buying and selling second-hand goods. The app allows users to list items quickly with photos and descriptions, creating a fast, intuitive, and social marketplace.

Carousell’s mission is to make selling and buying anything simple, fun, and accessible, promoting a circular economy and reducing waste. The platform has become one of Southeast Asia’s leading consumer marketplaces, with millions of users across the region.

Founding Story

Carousell was co-founded by Quek Siu Rui and Lucas Ngoo, two Singapore Management University alumni. Frustrated by the cumbersome process of traditional online classifieds, they envisioned a mobile-first solution that would allow anyone to sell items in minutes.

The founders started with a simple idea: a camera and a smartphone should be enough to sell an item. They built the first version of Carousell in a small office in Singapore, focusing on usability, social sharing, and speed. Word-of-mouth growth helped the app quickly gain traction among students and young professionals.

Funding and Growth Milestones

Carousell’s expansion has been fueled by strategic funding and regional adoption:

• 2012: Seed funding of $100,000 from angel investors, enabling the initial app launch in Singapore.
• 2013: Series A funding of $1.5 million to improve technology and expand user base.
• 2015: Series B funding of $6 million, growing to multiple Southeast Asian markets, including Malaysia and Indonesia.
• 2016: Raised $35 million in Series C to acquire competitors and enhance platform features.
• 2018: Series D funding of $85 million, bringing valuation to over $400 million and solidifying its position as a regional leader.
• 2021: Merged with 701Search (Carousell’s parent company) to become SEA’s largest classifieds marketplace, with millions of active users.

Carousell has successfully scaled across Southeast Asia, creating a thriving mobile-first ecosystem for second-hand goods.
