iSize Team

We are a team of 5 PhDs in video signal processing, machine learning and advanced networking systems, including two members who are University Professors in these areas. Advanced machine learning is now beginning to disrupt content delivery (albeit at its very nascent stages at the moment), and we believe we are the right team to allow for such advanced technologies to enter the market in a manner that is backward compatible to existing video encoding and transport standards. The CEO has an extensive background in finance, investments and business development.

We managed to deliver current technology with a very compact yet experienced team that includes a good mixture of very senior research and development staff with international experience and junior developers who have commitment to fast delivery.
