Wendy Liu was born in China and moved to Singapore at 17. She studied electrical and electronics engineering at Nanyang Technological University, graduating with first-class honours and a business minor. She later earned a master's degree in industrial and systems engineering at the National University of Singapore.
Early in her career she worked full time while studying part time for the master's degree. She joined the team behind 65daigou, a buy-for-me service that bought Chinese goods for shoppers in Singapore. It began in 2010 in He Jian's apartment.
The service was renamed ezbuy in 2016. It raised a Series A in April 2015, a $20 million Series B in 2016 and a $17.6 million pre-Series C round in May 2018. By 2018 Liu was the CEO of ezbuy.
In 2018 the Nasdaq-traded LightInTheBox acquired ezbuy, and He Jian became that company's CEO.
