According to Zhao Bin, founder and CEO of Agora, the backbone of the platform is the software-defined real-time network, which is the world's first and largest real-time audio and video network.

Agora is an application programming interface-powered company that allows customers to embed real-time video and voice abilities in their applications.

Lei Jun, founding partner and chairman of Shunwei Capital, said: "As the first round of leading investors in Agora, we not only see the important opportunity of real-time engagement on platform as a service that it has seized, but also the great ability of the founding team.

"The latest data showed that Agora gained a sales revenue of $64.43 million last year, which was a 41.6 percent increase year-on-year.

Shanghai-based Agora is a strong supporter of online education firm VipKid and Xueersi, a subsidiary of education giant TAL Education Group, as well as major intelligent sound bar firms.

By offering real-time communication networks, Agora is powering education firms to provide video, audio and livestreaming classes.

Clear and smooth cross-border communication is the first step," said Tao Siming, co-founder and chief technology officer of Agora.

Agora is just one example of a company offering services and cutting-edge technologies to companies and institutions in the flourishing education sector.
