KevJumba

Wu began uploading videos onto Youtube during his junior year of high school.[14] On February 26, 2008, the Los Angeles Times compared the web series Quarterlife's viewership to Wu's. At the time Wu was a "semi-well known YouTube blogger" and had received 450,000 views for a video describing how he broke his shin. Quarterlife, which had been picked up by NBC, had received only 100,000 views on MySpace and 50,000 views on YouTube.[15] By May 29, 2008, Wu had become one of three East Asians under the age of 21 to be in the top five of YouTube's all-time most subscribed users with 187,000 subscribers and more than 5.9 million views.[16] By June 5, 2008, he had become the number one subscribed comedian on YouTube, and third most subscribed uploader overall.[2] Wu's videos have received replies from Ella Koon,[17] Jessica Alba, and Baron Davis.[18]

In 2008, Davis created a "longest stare" contest for ibeatyou.com, a site that he and Alba's husband Cash Warren co-founded. The contest began with Davis challenging Wu, who then challenged Alba, who responded to the challenge.[19][20][21] In 2011, Wu began performing with Yesterday, Today, Forever (YTF) along with other YouTube personalities.[22] The group performed their first concert on October 9, 2011 in Honolulu, Hawaii.[23] In June 2012, Wu began starring in YouTube videos on a new channel called YOMYOMF. He stars in his own series titled KevJumba Takes All.[24]

As of September 27, 2013, KevJumba has remained inactive with no new uploads to the channel. As of August 2014, Wu had more than 3,000,000 subscribers and more than 350 million combined views on the videos in his main channel.[25] His combined video views total over 343.9 million. In early 2016, Wu privatized his videos on the KevJumba account, disabling all content to the public. However, the 35 videos on Wu's JumbaFund channel are still public. The privatized videos were later released again back to the public. He eventually uploaded two new videos titled "Hope." and "YOUTH REPRESENT" LIVE (Internet Power!)" in March 2017.

The web series Funemployed, launched in the summer of 2010, stars Wu and Philip Wang of Wong Fu Productions and includes other notable YouTube stars such as Nigahiga, David Choi, Kina Grannis, and Chester See. With the large number of fans, this series quickly took off and became a hit, reaching 500,000 viewers in only a few weeks. The series focuses on two good friends named Kyle (Wu) and Jason (Philip Wang), and how they are dealing with unemployment after Jason is laid off at work. Kyle is characterized as the typical laid back guy, who comes off as somewhat of a slacker, while Jason is characterized as the more studious hard worker of the two. The two eventually come up with an idea of how to make money, believing that YouTube is the key, an allusion to Wu's and Wang's real life success with YouTube videos. Funemployed eventually came to an end on July 27, 2010, with their last episode entitled, "Gave it a Shot". There were a total of eleven episodes.[26]

Wu launched the JumbaFund Youtube channel in 2009 with the mission of donating all of its earnings to a charity that viewers suggested.[14] Wu mentions this in his video and always records himself donating all the profits to the charity in order to show the viewers that his JumbaFund charity is not used for anything but to donate to the needy.

In 2011, Wu was invited by the nonprofit The Supply to teach English in Nairobi, Kenya. Wu uploaded the videos from his trip onto the Jumbafund channel upon his return to the US and donated over $5,000 in ad revenue to The Supply. The nonprofit in turn used the funds to finance the construction of the then titled "Jumba Lenana Academy" secondary school in the Lenana neighborhood where Wu volunteered. Jumbafund, up until this point, donated to various charities, such as the Red Cross and St. Jude Children's Research Hospital. However, in February 2012, Wu has stated that he will dedicate the channel's annual revenue entirely to completing the Jumba Lenana Academy. The school was finished in 2013 and renamed "KevJumba High School". Jumbafund ended up donating more than $50,000 to the construction of the school and Wu has expressed his intent to continue covering the facility's operational costs.[5][27][28]

On April 21, 2016, Wu resurfaced on social media after an almost three-year absence as he made a blog titled "Monk.College". Wu said on his blog that he left YouTube so he could meditate (having taken an interest in transcendental meditation) and go to college.[29] According to his blog, Wu currently resides in Houston, Texas. In August 2016, Wu privatized "Monk.College" for unspecified reasons.[8] In March 2017, Wu made his first public appearance at Youth Represent the World Concert in Stafford, Texas, and opened up about his car accident to the public for the first time. After another three-year hiatus, Wu started streaming on Twitch.

In May and June 2010, Wu participated with his father in filming for the 17th season of The Amazing Race, an American reality television game show. Upon this announcement, it was also the first time his dad's name, Michael, was revealed, which was kept anonymous since his debut. Wu officially announced his participation on Facebook on September 1, and on YouTube a week later.[39] The season premiered on September 26, 2010. Michael and Kevin's best placement was a third-place finish in Leg 2 and Leg 6. Their worst placement was a last place finish (9th) in Leg 3, a non-elimination leg. They ended up in seventh place and were eliminated in Leg 7 after being issued two 30-minute penalties for using a cab to travel between tasks on the leg when they were instructed to walk; another team had also issued a similar penalty and checked in after them, but only had one half-hour penalty, resulting in Kevin and Michael's elimination.

Wu began working on a film with Dante Basco and Kinetic Films LLC in late 2011. In December 2012, Wu released his first full-length feature film, Hang Loose.

Hang Loose is a comedy in which Wu, who stars as himself, goes to Hawaii for his sister's wedding but finds himself on a misadventure with his future brother-in-law (played by Dante Basco) that changes his life.[40] Other notable actors in the film include frequent collaborator Justin Chon as the main antagonist, BJ.[40]
