Learning through an overseas placement
Quek studied business administration at NUS, where the university identifies him with the Class of 2012. Its founder account links him, Marcus Tan and Lucas Ngoo to a year-long NUS Overseas Colleges placement in Silicon Valley. Exposure to startups helped them consider entrepreneurship as a practical route after university.
The problem they chose was close to their own experience. Selling unused gadgets and books through existing channels felt cumbersome. They proposed a mobile-first marketplace that reduced the work needed to create a listing and contact a buyer.

A three-person founding team
The team took its concept to Startup Weekend Singapore in March 2012 and won. Carousell launched in August that year. In a 2017 company interview, Quek recalled that the idea had nearly failed to make the selection stages; the event helped turn it into a workable proposition.
The same interview describes a division of labour. Quek concentrated on product priorities, Marcus Tan on design and Lucas Ngoo on coding. Their early work used wireframes to decide which functions mattered before implementing the service. This is a shared founding story, not evidence that Quek personally wrote the entire application.
From incubation to regional organisation
The founders worked from BLOCK 71, where an office and a community of other entrepreneurs provided a place to develop the service. The company account describes conversations with experienced founders and the practical discipline of working together. Product design was joined by the less visible work of building a team and finding users.
A later transaction changed the scale of that task. On 21 November 2019 Carousell announced an agreement to merge with Telenor’s 701Search classifieds businesses. The regional team was to be integrated, while Mudah, Cho Tot and OneKyat retained their names and platforms in Malaysia, Vietnam and Myanmar. The announcement identified Quek as the executive to whom those businesses would report.
Moving beyond a listing service
In the later NUS conversation, the founders describe a move towards recommerce: helping people transact in secondhand goods with additional services, rather than merely hosting advertisements. Payments, shipping and authentication-related services addressed convenience and trust concerns. Their purpose was to make participation easier for people who otherwise hesitated to buy or sell.
This account remains a participant explanation of the business model, not a guarantee that every transaction is safe or a measured environmental saving. The career’s concrete contribution lies in the product and organisational choices: simplifying the listing process, sharing work across three founders, building regional teams and extending the services around secondhand exchange.
