Soon after the video went viral, Max Sidorov, a Ukrainian immigrant living in Toronto who says he had been a victim of bullying as a child, started a campaign at fundraising site Indiegogo with a goal of $5,000, to help give Klein a vacation and posted it to reddit.[14][15] Within a few days of its creation, the fund had surpassed half a million dollars, and by June 25, over $650,000.[16] An Indiegogo spokesperson stated that the website was in touch with Klein, who would receive the money raised by the scheduled end of the fundraiser on July 20, 2012.[17] When the campaign ended on July 20, Klein's campaign had received a total of $703,833.[18] Klein stated that she planned to use $100,000 of the earnings to establish the Karen Klein Anti-Bullying Foundation, as part of the GiveBack Foundation.[18]

On July 27, 2012, Klein announced that she planned to retire as a bus monitor, calling it "a tough decision".[19]
