Dr. Mehmet Unsoy, Partner at Cartagena Capital and Former Chief Architect of Mobile Operator mmO2, Brings High-Level Experience to the Roundbox Brain Trust

Florham Park, NJ, January 16, 2006 – Roundbox, a provider of innovative software products for the mobile broadcast market, today announced that Dr. Mehmet Unsoy has joined the company as a technical advisor. Dr. Unsoy will add his 30 years of experience as a telecommunications technology executive/strategist of major corporations and start-ups in the data, IP and wireless industries to the growing roster of Roundbox thought leaders.

We are especially pleased to have an experienced veteran like Dr. Unsoy as a technical advisor, said Jim Nelson, founder and co-chairman of Roundbox. He has a valuable knowledge base given his deep understanding of deployment challenges, carrier-grade requirements and the next-generation operator network vision.

Dr. Unsoy will help guide Roundbox as it continues to be at the forefront of the mobile broadcast/ multicast market – delivering services leveraging multiple broadcast technologies. Part of what attracted Dr. Unsoy to Roundbox is the company's understanding of the entire mobile broadcast value chain – from content providers, operators and handset manufacturers to the end user experience. This knowledge gives the company a distinct advantage in this rapidly evolving market.

Roundbox has a powerful leadership team with seasoned entrepreneurs who know not only how to build software for the wireless industry, but who are thought leaders in developing compelling converged applications, said Dr. Mehmet Unsoy, partner of Cartagena Capital and former chief architect of mmO2. The company's vision is one which I believe is an essential path for mobile operators who plan on offering a diverse broadcast services portfolio. Roundbox's solutions will enable an entirely new class of services that go beyond video, revolutionizing the way people interact with their mobile devices.

Prior to joining Cartagena Capital as partner, Dr. Unsoy was vice president of technology and chief architect responsible for the mobile operator mmO2 in the UK, Germany, Ireland and The Netherlands; vice president Mobile Multimedia Architecture, British Telecom; former director Wireless Internet, Nortel Networks – Asia/Pacific US and Global; and former R&D director at Bell-Northern Research, Canada.
