Justin Sung is a learning coach and former medical doctor who teaches study and learning techniques. He studied medicine at the University of Auckland and worked as a doctor after graduating, according to a University of Auckland news article from February 22, 2023. The same article says he founded two social enterprises while at the university: Foster our Future, a mentoring program for high school students, and JTT, which offered career guidance and academic support to aspiring healthcare professionals in New Zealand. His YouTube channel lists New Zealand as its country.
He is co-founder, chief product officer and Head of Learning at iCanStudy, alongside co-founders Michael Tsai (CEO) and Ashton Sheares (CFO), according to the company's team page. The company behind the program is iCanStudy Pty Ltd, an Australian private company (ACN 644 853 967) registered as active since October 5, 2020, with a Victoria address, per the Australian Business Register. The company's terms state they are governed by the laws of Victoria, Australia.
He publishes on YouTube as @JustinSung, a channel created on March 19, 2020, which had 2.24 million subscribers, 888 videos and about 128.5 million views when read on September 13, 2026. The channel links to the iCanStudy program and to the Instagram account @drjustinsung. The company also runs a second YouTube channel, @icanstudystudent (194,000 subscribers on the same date). He gave a TEDxUOA talk titled "Stop Studying. Start Learning", which is listed on ted.com.
What he sells is the iCanStudy program, a self-paced online curriculum. According to the official website, it includes a diagnostic assessment, 104 video lessons (more than 50 hours), quizzes and drills, monthly live workshops with Sung, a workshop archive and coaching support with feedback. The published price is $399 billed yearly or $169 billed every four months, in US dollars per the terms and conditions, with a 30-day refund for new customers. The help center says the videos are not sold separately because the program requires coaching and feedback, and that personalized coaching with Sung normally starts at $1,000 per week with a waitlist of two to ten months. A financial hardship scholarship offers 15% or 30% off the subscription for applicants who meet documented criteria.
The company's own materials describe him as a certified teacher, researcher, top 1% TEDx speaker and guest lecturer at Monash University, and claim more than 30,000 learners; the University of Auckland article cited more than 10,000 learners in 120 countries in 2023. These figures come from iCanStudy or from material based on it, and no independent source for them was found.
On reputation: no FTC or ACCC action under his name or iCanStudy's was found in site searches of ftc.gov and accc.gov.au on September 13, 2026. No independent press coverage beyond the University of Auckland's own news article was located. His age or year of birth was not found in a reliable public source, and his current city of residence is not confirmed.
