Description
Tango is a successful, market leader, a live-streaming Platform with 450+ Million registered users, in an industry projected to reach $240 BILLION in the next couple of years.
The B2C platform, based on the best-quality global video technology, allows millions of talented people around the world to create their own live content, engage with their fans and monetize their talents.
Tango live stream was founded in 2018 and is powered by 350+ global employees operating in a culture of growth, learning, and success!
The Tango team is a vigorous cocktail of hard workers, creative brains, energizers, geeks, overachievers, athletes, and more. We push the limits to bring our app from “one of the top” to “the leader”.
The best way to describe Tango's work style is not to use the word “impossible”. And we believe that success is a thorny path that runs on sleepless nights, corporate parties, tough releases, and of course our users' smiles (and as we are a LIVE app, we truly get to see our users all around the world smiling right in front of us in real-time!).
