The group went head-to-head against three other acts in the final of the corporate entertainment competition, organised by Sternberg Clarke, at east London venue Troxy.
Beatvox competed against stand-up comedian and hip-hop improviser Chris Turner, pirate-themed music and comedy duo Jollyboat and impressionist Mikey Bharj.
Acts were given a brief ahead of the final to tailor their performances for an awards ceremony and dinner event.
After all performances the audience were asked to vote for their favourite act on Twitter by using a dedicated hashtag for each contestant. Beatvox claimed more than 65% of the overall votes.
Adam Sternberg, director at Sternberg Clarke, told Event: "I thought the competition showed off a huge variety of talented but unknown acts and demonstrated that these acts are very able to adapt themselves to a given brief, in such a way that they could clearly be used as a method to communicate a message about a product, service or launch and not just be seen as the ‘fluffy’ bit at the end of a gala dinner.
"Beatvox was amazing. It had it all. Very funny, great voices and the most amazing beatboxer."
