What is the BigBlueButton?

BigBlueButton is completely open-source and was created by a community of dedicated developers passionate about helping improve online learning. It is constantly evolving and improving through a dedicated, growing international user and developer community. To date, there have been more than a dozen releases of the core product, and each new release has seen the development of new features, testing, and documentation as well as improved community support. Our focus is singular: support teaching with improved, online tools that allow teachers to connect with students in ways that are synchronized, collaborative and fun.
Built for online learning, BigBlueButton was born out of the Technology Innovation Management (TIM) program at Carleton University’s Institute for Technology Entrepreneurship and Commercialization in Ottawa, Canada, and was launched externally in 2007.
BigBlueButton is built for teachers.

In the future, we hope to have our interactive app and online learning platform under our name if we need further expansion of our small business.
Founded last January 2021, and the main office is in New York City, USA. Thank you.
