About THEO Technologies

THEO is a fast growing scale-up on a mission to change the way the world streams video over the internet. We empower the world’s leading media and entertainment companies to deliver cutting-edge video services, efficiently and on any device. Our flagship product is THEOplayer which simplifies video streaming with a universal video player across different devices and platforms (browser, Android, iOS, Roku, ...) offering a variety of features like content protection, advertisements, analytics, and so on. Next to THEOplayer we work on the future of streaming with some innovative technologies like our own ultra low-latency streaming protocol HESP (High Efficiency Streaming Protocol).

In our industry it’s not the big fish eating the small but the fast fish eating the slow. Therefore we have a bias for action with a culture that is built on high performance and self-development. We believe a great workplace is stunning colleagues working together and inspiring each other to learn and grow.
