Simon began his career co‑founding the Zomba Group of music companies (including record label Jive Records) in the 1970s, building it into the world’s leading independent music and music publishing company. In the early 90s, he came to the USA and established a media company in Silicon Valley. In the mid 90s he was appointed Executive Vice President of Capitol Records and Blue Note Records in Hollywood and built Capitol Records & EMI’s emerging new media business into a successful and significant global enterprise that established new business models for the record and music publishing industry. He is known for discovering Will Smith and publishing YMCA.

In 1997, Simon correctly predicted that mobile phones would become the indispensable voice/social networking‑and‑music companion for consumers and their increasingly mobile lifestyles. He created a start‑up called Yourmobile and persuaded US and UK music publishers to embrace this new mobile medium by granting what would become the very first ring tone rights. Yourmobile became the first commercial ring tone company in the Americas, Europe, UK, Australia, and Africa, and spurred a new and international mobile entertainment industry. By 2003, Vivendi Universal purchased Yourmobile, renaming it Moviso, where Simon remained as an advisor. Today, Simon is popularly known as the ‘Father of the Ring tone.’

Between 2005 and 2009, Simon served as the mobile producer for three of the highest-profile, live global broadcast events in recent history. Live 8, Bono and Sir Bob Geldof’s nine‑city global concert, brought mobile connectivity to nine capital cities and an international television audience of over 800,000,000 viewers. This enormous people‑powered call‑to‑action resulted in the G8 countries reducing the debt of the world’s poorest nations. He was also the Mobile Producer of Al Gore’s Live Earth, the world’s first eco-centric global impact event that spanned 10 countries and brought the vital message and visibility of global climate change to a worldwide audience of over 500,000,000 television viewers and online participants. In 2009, Simon was the Mobile Producer for the TED.com’s Prize-winning project, Pangea Day, a global multi-platform broadcast featuring short films from international filmmakers, from around the world. By integrating a mobile/SMS layer to all these worldwide events, Simon helped set the standard for integrating mobile technology as an essential element in global television and major global event broadcasting.

The influential trade publication Mobile Entertainment magazine named Simon as one of the world’s Top 50 Executives in Mobile Entertainment for 2005, 2006, 2008 and 2010, and in 2007, he received its special award for Outstanding Contribution to the Global Mobile Entertainment Industry.

In early 2014 Mobilium Africa, its pan‑Africa subsidiary launched the first comprehensive, pan‑African and Africa‑specific mobile health delivery network known as the Smart Health Hub. With one billion Africans and some 800 million African mobile subscribers, Africa has the deep potential for mobile device growth across all sectors playing a key role in the development of the global mobile industry. Mobilium Africa has worked with The Global Fund for AIDS, TB and Malaria & the World Health Organisation (WHO), the official participants in Smart Health Consortium, as is SafePoint Single‑Use Syringes, and the support of the World Health Organization Maternal & Newborn Health arm (PMCNH). Smart Health Hub is part of a wider range of mobile commerce, software and innovation that Mobilium has begun to bring to the entire African continent embodying mobile health, mobile wallet technology, mobile payment systems and new ways of using mobile gamification, mobile social messaging, mobile social music and mobile social lifestyle research into creating better lives for digital citizens everywhere.

Simon also works closely providing high‑level mobile media and content guidance and counsel to global thought leaders, media companies, media properties, and creative artists to identify global mobile revenue opportunities and shape their mobile strategies worldwide. In addition, he works closely with the GSM Association, the global governing body of the international mobile phone industry. The GSMA organises the annual Mobile World Congress in Barcelona – 106,000 attendees and over 170 Ministerial delegations.
