Carousell is a mobile lifestyle marketplace that enables people to buy and sell items, with sellers able to create a free listing in 30 seconds. Its founders, Siu Rui Quek, Lucas Ngoo and Marcus Tan (pictured), all spent a year in Silicon Valley as part of their National University of Singapore overseas college programme and left inspired to use technology to solve problems on a large scale.

Launched in Singapore, the company has over 35 million new and second-hand items listed for sale, at up to 80% below retail prices. The business was started in 2012 and now has a presence in 13 cities around the world.

In 2014, the company raised $6m (£4.1m) in funding led by Sequoia Capital, backers of Apple and Google, and it is looking to raise an additional $50m (£34.68m) to expand its reach across Asia. In January 2016, the company announced its Carousell Groups feature, enabling people to discover and join groups.
